1.1 Objective
The overall objectives of the PTW system are:
• to ensure that all necessary measures are taken to provide a safe working environment by
identifying the potential hazards and risks ahead of starting work;
• to ensure that everyone involved in the work is fully aware of the content of the work, any potential
hazards and the controls for the hazards identified and any recovery measures necessary should
control or controls fail;
• to prevent incidents that may lead to harm to People, Environment, Asset or Reputation (PEAR).
Meeting the objectives:
To ensure that these objectives are met, all elements of the PTW system must be operated effectively. It
is important to understand that the system is not just completion of the permit forms, certificates and
safety checklists, but requires the proper application of the following:
Audit
Authorisation
A process to verify that the requirements of the Permit to Work Procedures are being
met and identify that common standards are being applied.
Authorisation, both before work starts and restarts after a significant break, confirms
that all controls have been checked as being in place and that the worksite is properly
prepared for work to start or restart.
Communication Full communication between AS/AA/WSS is necessary at all stages in the life cycle of
the permit.
Competence
Co-ordination
Housekeeping
Planning
Controls
Supervision
Toolbox Talks
Training
Demonstration by AS/AA/WSS/AGT of having the necessary knowledge, experience
and application skills to fulfill their role in the system. Competence is assessed during
training, appointment and audit.
The process designed to ensure that any work that would conflict with other work is
not authorised to proceed at the same time and at the same location.
Ensuring that the worksite is properly prepared, clean, clear, safe and free from
obstructions whilst the work is progressing, when it is complete and when the
worksite is unattended.
The process that ensures work is properly prepared, including the completion of the
appropriate job hazard analysis and certificates or method statement required.
The process that ensures the conditions under which work can proceed.
The process of preparation of each worksite, and the responsibility of supervising
activities at the worksite to ensure compliance with the controls specified on the
Permit to Work.
The process of discussion at the worksite to inform all those involved in the work of its
content, how it will be carried out, allocating individual responsibilities and identifying
the necessary controls and recovery measures that should be in place before the work
starts.
Formal instruction prior to appointment to provide adequate understanding of the
system.
Work Description A clear and detailed description of the proposed work.
The PTW System will only meet its objectives if everyone involved carries out their role within it
effectively. These roles are described in Section 1.3 of this procedure.
Permit to Work Procedure – Rev. 4.2 Page 11 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
For all work covered by a permit, everyone associated with the job:
UNDERSTANDS
The work and how it will be carried out;
The work environment and any problems associated with it;
The potential hazards, and the controls that are required;
Their own responsibilities;
Any recovery measures that may be necessary should control fail.
COMPLIES
REMEMBER
with all of the controls on the permit, to ensure the continued safety of those doing
the work and the installation on which it is being done.
THE ISSUE OF A PERMIT DOES NOT GUARANTEE THAT NO INCIDENTS MAY
OCCUR AT A WORKSITE. TO PREVENT INCIDENTS OCCURRING, THE HAZARD
AND EFFECT MANAGEMENT PROCESS IN WHICH THE HAZARDS HAVE BEEN
IDENTIFIED, ASSESSED AND CONTROLS PUT IN PLACE MUST BE COMPLIED
WITH THROUGHOUT THE DURATION OF THE WORK.

identified in the Work Description to commence or re-commence during their period of duty. The AA
must have successfully completed the appropriate PTW courses (PTW-2, 3 & 4 or PTW-5 when expired)
and have been formally appointed. The AA must comply to the requirements of Box 2 of the permit
should it require them to be continuously present at the worksite.
1.3.7 Permit Issue Point Coordinator (PIP Coordinator)
The PIP Coordinator is a person who has successfully completed the appropriate PTW courses (PTW-2,
3 and 4 or 5 when expired) and been formally appointed by the relevant AU Appointing Authority to be in
charge of and responsible for managing the PIP daily activities associated with the PTW process
maintaining visibility at all times of the current status of all permits. The PIP Coordinator is
responsible for overseeing the PTW activities within their area to ensure compliance is maintained
through constant communication with those responsible for applying it.

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
The PIP Coordinator will:
• Ensure the PIP location board information is kept up-to-date especially the plot plan layout.
• Ensure up-to-date filing of EPI & FSR variations are maintained and make site visits to the location
to ensure site isolation tags for EPI are still readable and in good condition.
• Maintain an up-date list of appointed WSS, AS, AA and Gas Testers for their respective areas.
• Be competent in applying the PTW Procedure (Module 03).
• Be responsible for overseeing the PTW process from Application to Cancellation of permits and
subsequent archiving.
• Check all permits at application to ensure that the HEMP process has been properly conducted and
all authorised permits to ensure controls required are complied with.
• Discuss with the relevant Supervisor proposed permits to minimise disruption to operational
activities due to PTW delays.
• Prepare PTW audit schedules for Levels 4, 3 and 2, ensure action items are inputted in FOUNTAIN
and ensure the necessary action is taken by the relevant action parties.
• Organise & update Portable Gas Detectors inventory.
• Check and ensure PTW documents are correctly filled-in and completed prior to archiving.
• Keep a set of master isolation certificates of each platform or area under their responsibility.
• Provide coaching where necessary.
1.4 Documentation Storage
When a permit and the associated certificates have been cancelled, they are removed from the permit
rack together with the accompanying check lists or hazard analysis. These plus any tags that may have
been used and/or certificates are stored in the PIP. Permits are stored by type initially for a period of 1
month for immediate access. After 1 month, they can be put into bulk storage and remain there for 6
months. They can then be disposed of using the BSP approved Waste Disposal Process UNLESS they are
linked to an incident.

Restrictions on Number of Concurrent Hot Work Activities
For each installation, the SOS is to set a limit on the number of Hot Work Permits that may be
authorised at any one time. This limit should also take into consideration whether the installation is
live (SIMOPS) or shutdown and during night time or hours of darkness and has containment. The
limit should be determined by the weekly cumulative risk assessment (BSP-02-Guideline-022,
HAZID), and must be formally recorded at all times in the PIP.
Work Incompatible with Hot Work
Hot work in progress, other than in pressurised non-hazardous areas (habitat) is to be stopped if any
of the following activities are to take place on the same platform or jacket offshore or within 15
meters radius onshore.
a) Flammable liquids are to be transferred.
b) Spray Painting.
c) Hydrocarbons are or may be, released by bleeding down a process system, breaking containment,

This chapter describes in detail the steps required to complete and process a Permit To Work Application
Form .
Note: For Electrical Permit applications please refer to BSP-02-Standard-1629 (Module 10).
3.1 Completing a Cold Work, Hot Work and Equipment Disjointing Permit
For details of the permit forms, reference is made to Appendix 4.
3.1.1 Box 1 - The Work Description
The person applying for a permit should be the WSS.
The WSS must complete Box 1 of the permit, entering:
• the work description
• the installation and worksite
• the planned start and finish dates and times for the work
• previous permit number, if applicable
• his name, signature, the date, the BSP dept. or contractor he works for and the BSP contact tel.
no.
• identify in the YES/NO box if electrical isolation is required.
• The number of the appropriate certificate in Box 4 (if applicable) to make the link.
Additionally, on a HOT WORK permit, justification for the hot work must be given and an indication of
whether the task to be performed is hot work on a live production facility.
When Box 1 is complete the WSS attaches any supporting documents, for example certificates on
which he has completed the ‘Application’ section, to the permit.
The WSS must ensure that:
• the installation and work descriptions are clear.
• the work described does not begin until the permit has been approved, accepted and authorised.
NO WORK shall be carried out without the required signatures on the permit.
• there is a WSS for all periods when work is carried out under the permit.
• the permit passes through each stage of the permit process until it is cancelled when the work is
complete, the permit is suspended or re-authorised.
He then submits all copies of the permit and the supporting documents to the Authorised Signatory for
review and approval.
Permit to Work Procedure – Rev. 4.2 Page 20 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
3.1.2 Box 2 - Protective Equipment and Worksite Supervision, and Task Box
The AS has to ensure that the Task and No Box is completed, and complete Box 2 following discussion
with the WSS. During this discussion he will ensure he understands the work planned and therefore
the protective equipment and level of supervision attention necessary.
Continuous attendance of a WSS is mandatory for all hotwork activities, work must stop when the
supervisor is not at the worksite.
The hazardous area classification must be identified and the AS must ensure that the WSS
understands the significance of the entry.
If there is a need to temporarily re-classify the Area Classification drawing, the area affected
should be highlighted on the drawing and attached to the permit.
3.1.3 Box 3 - Hazard Identification and Special Precautions
Before completing Box 3 the AS must discuss and agree with the WSS the possible hazards and the
special precautions necessary to perform the work safely. PTW Application is to be supported by a
Hazard Checklist, Hazard Identification Plan or both.
The identified relevant controls listed in box 2 in the HCL should be transferred to the Permit, and
worksite controls identified in box 10 of the SCL should reviewed by the AS together with the WSS.
In addition the AS should check if there are any other controls identified in Part 5 of the HSE Case that
may be applicable to the work.
The information included in Box 3 must be clear and specific. Entries like ‘Follow HSE Standards’ and
‘Refer to attached’ are not acceptable. The specific standard and the appropriate part of it must be
identified,
In addition, for a HOT WORK permit, the AS enters the precautions necessary to minimise the risk of
fire and the gas testing frequency. Precautions will be indicated by ticks in the ‘Required’ boxes. The
‘Check’ boxes remain blank at this stage.
Standard precautions, e.g. obey platform alarms, need not be included.
If the AS does not require any special precautions to be taken, and there are no potential hazards, he
is to write ‘NONE’ in Box 3.
The AS is responsible for:
• agreeing in principle that the work may take place on the equipment concerned.
• ensuring that the work description is clear, complete and correct.
• agreeing worksite hazards, worksite preparations, control and recovery measures.
Permit to Work Procedure – Rev. 4.2 Page 21 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
Where there are potential hazards of which the persons undertaking the work might be unaware, work
on adjacent sites, chemical hazards, pressurised equipment adjacent to the worksite, overhead
electrical power lines for example, the Authorised Signatory is to list them in Box 3.
3.1.4 Box 4 - Supporting Documents and Certificates
The AS also completes Box 4. The AS must discuss and agree with the WSS whether additional
supporting documents and/or certificates are required.
The AS ticks the appropriate columns to indicate those required. The AS is to ensure that the WSS
completes the application section of any certificates required but not already attached to the permit.
If electrical isolation is identified in Box 1, the AS must discuss and agree the appropriate electrical
documentation required with the SAEP or AEP who raises and approves the electrical documentation.
The AS is to ensure that the numbers of all certificates are entered in Box 4 and that all necessary
certificates are attached to the permit.
The ‘Initial Checked’ column will be left blank at this stage.
When the Hazard Checklist (or Method Statement / HIP if checklist is not available) is attached to the
permit, the AS is to ensure that he is satisfied with the contents.
It is occasionally necessary to issue more than one permit for work on equipment which has been
isolated, either Electrically or Mechanically, for example to carry out separate maintenance activities
on a pump and motor set where an Isolation / De-isolation Certificate (Electrical) and / or an Isolation
/ De-isolation Certificate (Mechanical) has been issued. In these cases the multiple permits shall be
treated as separate elements of the same task and the additional procedure described in Chapter 4,
para. 4.2 shall be used.
Where there is a requirement to ‘Break the integrity of a system’ an Equipment Disjointing Permit is to
be raised prior to the Hot or Cold Work Permit being approved in Box 5a).
The AS is responsible for ensuring that all necessary preparations such as isolations, depressurising,
purging, cleaning, scaffolding or the provision of special equipment have been identified and included
on the permit and associated certificates.
The Performing Authority (PA) must ensure that the personnel who sign permits on their behalf
are competent to discuss the contents of the permit with the Authorised Signatory. If the Asset
Holder is not satisfied with the performance of a PA, they may replace the PA concerned.
Permit to Work Procedure – Rev. 4.2 Page 22 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
3.1.5 Box 5 - Approval of the Permit
The term ‘Approval’ means that the information in Boxes 1, 2, 3 and 4 has been checked and accepted
by the AS and that the work is agreed in principle. It does not mean that the work identified in the
‘Work Description’ can start.
Preparation of the worksite for the intended work may not start until the permit has the Approval of the
AS at Box 5a. Worksite preparations may include most items necessary in order to make the site safe
for the intended work, including erection of barriers, valve isolations, sealing of drains, etc. Breaking of
containment and / or the insertion of spades are NOT permitted as worksite preparation without the
issue of an Equipment Disjointing Permit (see para. 3.1.2)
The AS indicates the maximum period for which the permit will be valid.
approved for periods longer than is necessary to complete the work.
Permits should not be
- COLD WORK PERMIT ≤ 14 days;
- HOT WORK PERMIT ≤ 7 days:
- EQUIPMENT DISJOINTING PERMIT ≤ 9 days
- DIVING OPERATION PERMIT ≤ 5 days
The AS will refer to the planned work schedule in Box 1 to when setting the validity period.
The AS communicates with any other departments or work groups whose actions may be affected by, or
have an effect on, the proposed work.
If electrical isolation is identified in Box 1 the Responsible Person Electrical (RPE) will also sign in Box 5
to agree the electrical isolation and documentation required.
To ensure that all hazards are identified and precautions and mitigations are in place, the AA must
visit the worksite, together with the WSS, to plan the work before authorising the permit.
All 3 copies of the permit are held in the ‘PLANNED’ section of the permit issue point rack until the
permit is required to be authorised by the AA.
3.1.6 Box 5b - Release by Asset Custodian
It may occasionally be necessary for work to be carried out on an asset where the Asset Holder
representative is not an appropriate person to accept responsibility for supervision of the works. This
usually occurs where the works are of a specialist nature, or are outside the competencies of the Asset
Holder. In these circumstances the Asset Holder representative may temporarily release all or part of
the asset to the PA, who then accepts supervisory responsibility for the works as a temporary Asset
Holder. The Asset Holder releases their assets for the work specified by signing box 5b.
Permit to Work Procedure – Rev. 4.2 Page 23 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
3.1.7 Box 5c - Acceptance by Temporary Asset Holder
The temporary Asset Holder signs Box 5c as formal acceptance for the duration of the work. This
agreement is terminated by completion of Box 9 of the permit
3.2 Completing an Equipment Disjointing Permit
Where there is a requirement to ‘break the containment integrity of a system’, disjoint plant or
equipment, an Equipment Disjointing Permit is to be raised prior to the Hot or Cold Work Permit being
approved in Box 5a.
3.2.1 Box 1 - The Work Description of Equipment to be Disjointed
Box 1a - Description and Location of Equipment
The applicant describes accurately the equipment to be disjointed and the exact location. Unique
identification numbers must be quoted when these exist and reference to the associated Hot or Cold
Work Permit must be included. A site plan may also be attached.
All the information required to enable unique identification must be entered clearly on the permit
including time schedule giving details of planned time and date of commencement and finish.
Box 1b - Description and Location of Disjointing
This box must identify the type of disjointing required (spading, blanking, line removal and blanking, for
example) and its exact location.
A sketch will often be helpful. If provided, it should be identified in this box.
When Boxes 1a and 1b have been completed, the applicant submits all copies of the permit to the
Authorised Signatory for review and approval.
3.2.2 Box 2 - Protective Equipment and Worksite Supervision
The AS is to complete Box 2. The AS will tick the appropriate boxes to indicate the requirements for
Personal Protective Equipment and other equipment required at the worksite. When a continuous
worksite presence by a representative of the Asset Holder or the WSS is required, this is to be identified.
Where continuous attendance of a WSS or Asset Holder representative is required, work must stop
when that identified supervision is not available at the worksite.
Permit to Work Procedure – Rev. 4.2 Page 24 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
Where continuous presence is not required the WSS or the Asset Holder is to satisfy themselves that the
worksite is safe, but they may leave the worksite to perform other duties. The WSS must visit the
worksite as frequently as is necessary to ensure that the controls established by the permit are being
complied with. The Asset Holder's representative (normally represented by the AA) should make such
visits to the site, as they considers necessary, depending on the potential hazards associated with the
work.
3.2.3 Box 3 - Hazard Identification and Special Precautions
The AS completes Box 3 indicating the last proven condition of the system, the hazards involved and the
special precautions necessary to control them.
Standard precautions, obey platform alarms for example, need not be included.
Where there are any potential hazards of which the persons undertaking disjointing should be aware,
the AS is to list them in Box 3. This might include the release of high-pressure fluid when the flange is
broken, any special care needed when unbolting, additional protective equipment required and
preparedness for any ensuing spills.
The authorised signatory enters that the EQUIPMENT HAS CONTAINED AT
°C AND BARG.
3.2.4 Box 4– Precaution Taken and Supporting Documents
The AS is to:
• identify and agree the hazards.
• identify in the YES/NO Box controls required.
• identify in the YES/NO Box controls taken.
• tick in the Reqd column certificates required.
• ensure the certificate number is entered on the Equipment Disjointing Permit.
• attach associated documents to the Equipment Disjointing Permit.
3.2.5 Box 5 - Approval of the Permit
The AS signs that they agree that worksite preparations for example valve isolations can begin. Their
signature here does not allow the disjointing work to proceed.
Permit to Work Procedure – Rev. 4.2 Page 25 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
3.3 Worksite Preparations for Cold, Hot and Equipment Disjointing Permits
The next stage in the process is to carry out all preparations required to make the worksite safe for the
work to start. The original copy of the permit, with its supporting documents attached is removed from
the ‘Planned’ section of the permit rack and displayed at the proposed worksite. This stage involves
physical preparations such as providing fire fighting equipment and barriers, and immediately before
hot work or confined space entry commences, gas/oxygen testing.
Whilst worksite preparations are in progress the green and white copies of the permit are kept in the
‘Planned’ section of the permit rack.
3.3.1 Isolations
For a detailed procedure on mechanical and electrical isolations, see Chapter 5.
3.3.2 Recording Worksite Preparations
When the requirements of each certificate covering worksite preparations are met, the ‘Initial checked’
section in Box 4 on the Hot or Cold Work Permit is completed by the AA.
For an Equipment Disjointing Permit, all ‘YES/NO’ pairs must be completed by the AA.
Where valve isolation or equipment disjointing is required at a location remote from the work, and
under the control of a different Asset Holder, the AA of that area obtains a copy, which may be faxed,
of the Isolation Certificate or Equipment Disjointing Permit, certifying that the other relevant isolation
or disjointing is complete. These are kept together with the permit documentation at the permit issue
point. The original of this isolation certificate is retained at the permit issue point controlling the area
where the isolation was carried out.
3.4 Gas Testing Requirements
3.4.1 The Authorised Gas Tester
Authorised Gas Testers (AGT) are appointed as described in Appendix 2. Before and during hot work,
entry to confined spaces or excavations, an AGT must:
• carry out gas tests as specified on the Permit or Confined Space Entry certificate, or when
required by permit signatories.
• sign all copies of the permit or certificate after carrying out a test indicating "SAFE" or "UNSAFE",
with name, time and date.
3.4.2 Box 11a – Initial Gas Testing
An initial gas test shall be carried out in the area affected by the proposed work, IMMEDIATELY prior
to permit acceptance.
Permit to Work Procedure – Rev. 4.2 Page 26 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
The AGT carries out gas tests under the direction of the relevant AA, who is responsible for
authorising the permit.
THE GAS TESTER MUST ENSURE THAT HIS INSTRUMENTS ARE VALID, CALIBRATED AND
FUNCTIONING CORRECTLY BEFORE CARRYING OUT THE TESTS.
3.4.3 Procedure if Flammable Gas is Found When Testing for Hot Work
If gas or other potentially explosive / flammable concentrations are found then the WSS and the AA,
are informed. No source of ignition is to be allowed to enter the affected area.
Both the pink and green copies of the Hot Work Permit are to be handed back to the Area Authority
who determines the cause and arranges to take whatever action is necessary to make the facility safe.
All copies of the permit are returned to the planned section of its permit rack and repeat gas tests are
performed until the area is considered safe for work.
Only when the Gas Tester and AA are satisfied that the area is safe for hot work, shall permit copies be
removed from the planned section of the permit rack.
Work is not to proceed unless the permit has been accepted by the WSS and authorised by the AA.
3.4.4 Box 11b - Record of Additional Gas tests.
The AA must ensure that gas testing is carried out by an Authorised Gas Tester at the frequency
stated on the permit and that these tests are recorded in Box 11b of the worksite copy of the Hot Work
Permit. Gas tests are to be carried out after each break and whenever the worksite is unattended for
over 1 hour and as required by Box 3.
If the gas tests are not carried out in accordance with the requirements of Boxes 3, 11a and 11b of the
Hot Work Permit the WSS is to suspend all work and return the permit to the AA.
If gas testing indicates it is not safe to work, the Authorised Gas Tester must IMMEDIATELY instruct
the WSS to stop work, tick the ‘UNSAFE’ box and enter the time and result of the test and return the
permit to the AA so that the permit can be suspended.
If a hazardous atmosphere is found at any time the permit must be suspended as described in para.
3.1.11.
Further space for recording gas test results is provided on the reverse side of the worksite copy of the
Hot Work Permit.
Permit to Work Procedure – Rev. 4.2 Page 27 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
3.4.5 Initial Gas/Oxygen Testing for Confined Space Entry
Refer to BSP-02-Standard-1645 (Module 07).
When the permit includes confined space entry the work area is to be tested to ensure that it is free
from flammable/toxic vapours, and is within required limits for oxygen concentration, IMMEDIATELY
prior to acceptance of the permit.
If oxygen deficiency or unacceptable concentrations of other hazardous gases are found, the AA and
the WSS of the team due to enter the confined space must be informed.
Both pink, blue and green copies of the work permit, including certificates, will be handed back to the
AA who must take the necessary action to make the facility safe for the proposed entry.
All permit documentation will be returned to the planned section of the permit rack and repeat gas
tests taken until the confined space is safe for entry.
When the Gas Tester and AA are satisfied the confined space is safe for entry, both the pink, blue and
green copies of the work permit, including certificates, are to be removed from the planned section of
the permit rack.
The Authorised Gas Tester will enter the result in Box 3 of the Confined Space Entry certificate, with
the time of the test and their signature.
The permit must be accepted by the WSS and authorised by the AA before personnel can enter the
confined space.
If the gas tests are not carried out in accordance with the requirements of Box 3 of the Confined Space
Entry certificate, the WSS must suspend all work and return the permit to the AA.
3.4.6 Gas Tests
Additional gas test records and re-validation for confined space entry must be recorded on the reverse
side of a Confined Space Entry certificate.
If flammable or toxic gases or oxygen outside the prescribed limits are found at any stage, the Permit
and Confined Space Entry certificate must be SUSPENDED (refer to operational Module 07, Confined
Space Entry).

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
3.5 Acceptance and Authorisation of Cold, Hot and Equipment Disjointing Permits
3.5.1 Box 6 - Acceptance by the Worksite Supervisor
By accepting the permit, the WSS confirms that:
• they fully understands the work and all worksite controls given on the Hazard Check List are in
place, signed off and worksite controls understood;
• everyone engaged in the work (including shift / crew changes) is fully briefed about the work and
precautions necessary.
• all precautions, including those on any associated certificates, will be observed.
• gas testing (as requested) has been completed in Box 11a
• the permit is displayed at the worksite whenever work is in progress.
• no work takes place unless the permit is authorised for that working period by the Area
Authority.
• the worksite and equipment affected by the work have been left in a safe condition at each shift
change. On completion or suspension of work, he will sign Box 8c of the permit to confirm this.
• they will stop work if the gas test required in Box 3 of the Hot Work Permit and/or the Confined
Space Entry certificate are not carried out.
• They will return the permit and any associated certificates are returned to the permit issue point
whenever work stops for more than 4 hours and inform the AA of his action.
The WSS is to be at the worksite at all times.
By signing Box 6 in the presence of the AA, the WSS accepts responsibility to maintain the worksite in
a safe condition during the proposed work.
The WSS must not sign the permit acceptance unless he is satisfied that the worksite is safe.
3.5.2 Box 7 - Authorisation by Area Authority (Hot/Cold Work and Equipment Disjointing Permit)
For onshore work under the control of departments other than those in the operations function, the
AA will be provided by the department carrying out the activity.
Where the AA is provided by the department responsible for executing the work, Boxes 5b and 5c will
be completed to transfer the asset temporarily to that department.
Prior to Authorisaton of the permit the AA must visit the proposed worksite, together with the WSS to
verify that:
• all the controls and instructions listed on the permit have been carried out to his complete
satisfaction.
• all disjointing permits and valve isolations are in place and holding.
• all certificates and isolation tags are attached to the appropriate copies of the permit and have
been completed correctly. They initial the ‘Check’ column on the work permit in Box 4 to indicate
this.
• no other hazards have become evident or further precautions needed. If so they must amend the
conditions on the permit or delay authorisation until the additional hazards have been controlled.

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
• any required gas testing has been carried out with satisfactory results, and has been recorded in
Box 11a of the Hot Work Permit and, if required, on the Confined Space Entry certificate.
A WORKSITE SUPERVISOR MAY NOT SELF AUTHORISE A PERMIT - IT MUST BE AUTHORISED
BY AN INDEPENDENT AREA AUTHORITY i.e. BOXES 6 AND 7 MUST BE SIGNED BY DIFFERENT
PERSONS.
Once the AA is satisfied that the worksite is safe for the work to commence AFTER formal acceptance
by the WSS, they will complete Box 7 of the permit and specify the period for which the first
authorisation is valid. This period must be no longer than 12 hours.
NO WORK MAY TAKE PLACE UNDER THE PERMIT UNTIL IT HAS BEEN ACCEPTED BY THE
WORKSITE SUPERVISOR AND AUTHORISED BY THE AREA AUTHORITY.
3.5.3 Actions After Authorisation
When the permit has been signed by both the AA and the WSS the top worksite copy is handed to the
WSS together with the worksite copy of any associated certificates and the accompanied Hazard
Checklist. The WSS is responsible for ensuring a proper TBT (see Section 3.11) will be held and the 3-
whats (see Appendix 12) risk assessment will be carried out. The WSS has to ensure that the permit is
displayed in a permit holder, at a prominent, safe position at the worksite. It remains there whilst
work is being carried out.
NO WORK IS TO BE CARRIED OUT UNLESS AN AUTHORISED PERMIT IS CLEARLY DISPLAYED
AT THE WORKSITE.
The remaining copies of the permit, any accompanied documents and any associated certificates, will
be placed in the AUTHORISED section of the permit rack, at the permit issue point (PIP).

3.6 Box 8 - Permit Re-Authorisation
3.6.1 Box 8a - Permit Re-accepted, Re-Authorisation
When PTW’s are handed over to oncoming WSS & AS eg. at shift changes, the permit responsibilities
are transferred to the oncoming WSS & AS who MUST sign as the respective new WSS & AA.
AS accept responsibility for all the permits at their formal shift change handover.
Box 8a - Acceptance by Worksite Supervisor (Hot and Cold Work Permits)
The oncoming ( eg. after shift change, crew change, etc) WSS will satisfy themselves that the worksite
is safe and that all safety controls stated on the permit are in place before signing to accept the permit.
The WSS acceptance signature will be provided on both the worksite and permit rack copies of the
permit.
The WSS will display the worksite copy in a permit holder at a prominent place at the worksite. The
permit rack copy will be placed in the AUTHORISED section of the permit rack.

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
3.6.2 Box 8b - Re-Authorisation by Asset Holder (Hot and Cold Work Permits)
At the start of each new shift, an AA must re-authorise any permits required for that shift. He will do
this by signing Box 8b of the PINK/BLUE and GREEN copies of the permit.
The AA will specify in Box 8b of the permit form the period for which the re-authorisation is valid.
This period must be no longer than 12 hours, or the end of the shift worked by the AA, whichever is
the sooner.
Before signing the permit to re-authorise it the AA is to carry out an inspection of the worksite.
3.7 Permit Suspension
A permit must be suspended if :
• an unsafe condition develops which requires that the work is stopped (e.g. gas/oil leak, platform
alarm occurs, reportable incident occurs, etc).
• the work is delayed or interrupted for more that 4 hours.
• the authorisation period expires.
• the work needs to be stopped to allow conflicting work of a higher priority to proceed.
• the gas test confirms that it is not safe to work
• the asset holder intervenes to interrupt work or withdraw a permit before completion.
• For testing of electrical equipment.
Suspension of work must always be carried out in accordance with the procedure outlined below.
Verbal communication is not acceptable except in the event of an emergency.
Permit to Work Procedure – Rev. 4.2 Page 32 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
3.7.1 Box 8c - Permit Suspension
To suspend a permit the WSS takes the following actions:
• check that the worksite and equipment affected by the work have been left in a safe condition.
• take the permit to the permit issue point for retention until work is to re-start.
• sign Box 8c of the PINK/BLUE and GREEN copies of the permit to confirm that work has been
suspended.
In areas where it is not possible to return the worksite copy of the permit to the permit issue point, the
WSS is to sign Box 8c of the PINK/BLUE copy only. The WSS will place this in a secure location and
notify the permit issue point by fax or radio that the work has been suspended and where he has left
the permit.
All copies of the permit together with associated certificates are to be placed in the SUSPENDED
section of the permit rack.
If work is to be suspended beyond the permit validity period given by the AS in box 5a, the permit
must be cancelled. When a permit is SUSPENDED, no work covered by the permit may be carried out
until it has been re-authorised. Worksite and permit issue point copies of all suspended permits are to
be retained in the permit rack by the Asset Holder.
3.8 Remarks Box
A remarks box is provided on the reverse of the worksite copy of the Hot and Cold Work Permits. This
may be used by the WSS to record the state of work on the completion of a working period for use by
themselves and the AA.
3.9 Permit Cancellation
A permit is cancelled when any of the following conditions are satisfied:
• the work is complete.
• the work is to be suspended, and it is known that work will not re-start until a date outside the
permit validity period.
• the permit has reached the end of its validity period given for the work.
• the content of the work is found to be different from that covered by the work description at Box 1,
when a new permit will be raised.

3.10 Completing a Diving Operations Permit
3.10.1 Box 1 - Application and Description of the Work
For a Diving Permit the Performing Authority (PA) may be either the CSR or the Diving Supervisor
provided they have completed the appropriate courses PTW 2, 3 and 4 and been appointed.
Prior to applying for the Diving Operations Permit the scope of the work has to be discussed and
agreed between the Diving Supervisor or Company Site Representative (CSR) and the Operations
Supervisor (FOS, COS or SOS).
The Performing Authority (PA)
The Diving Supervisor or CSR where appropriate applies for the permit. They complete the first two
sections and submit the permit to the AS responsible for the area in which the diving and/or ROV
work will take place. This should be done by fax for standard operation or in person for non-standard
operation.
If the application is by fax the AS will accept the faxed application by raising a new diving permit (from
the details on the fax). They will cross-reference the new Diving Permit with the faxed application by
entering the faxed number in Box 1 of the permit.

3.10.2 Box 2 - Description of the Work
The Applicant must specify the type of diving operations to be carried out. There are two types of
diving operations, Routine and Non-Routine.
“Routine Diving Operations” covers Underwater Inspection (DUI) using a ROV and/or diving personnel.
Leak investigation using ROVs (but not divers in the water) is also considered a routine operation.
Examples of Standard Diving Operations:
• Structural Integrity Survey
• Investigation on sub-sea pipeline for leaks by ROV
“Non Routine Diving Operations” cover all other diving activities. For such activities the CSR or
Diving Supervisor must discuss with the AS the work proposed and agrees the controls necessary in
order to complete the Diving Permit. Diving Permits do not only authorise divers to dive, but also carry
out the activities described in Box 2 of the permit. Hot or Cold Work permits to perform work
underwater are not required as they are covered by the Diving Permit but an EDP may be necessary in
the event of mechanical isolation.
Examples of Non Routine Diving Operations:
• Underwater Construction Work
• Anode replacement
• High pressure water jetting
• Pipeline and riser repairs
• High Voltage Cable surveys or replacement
• Underwater inspection of Vent Jackets or Damaged structures
• Diving near to Flares
Note that: Some tasks may start as routine diving activities and then become non routine. E.g. Leak
Investigation is initially a routine diving operation, but once a leak is verified and located then the leak
repair will become a non-routine diving operation. In this case an EDP may be required in addition to
the Diving Permit.

3.10.3 Box 3 - Safety Precautions during Diving Activities
The AS, following discussions with the CSR/Diving Supervisor, identifies in Box 3 all safety controls
required during the diving work. The AS ticks in the appropriate column to identify mechanical or
electrical isolations required and/or other supporting documents. The AA initials ‘Initial Checked’
column is to be left blank at this stage.
If the application is by fax, and an Isolation/De-isolation Certificate (Electrical) is required, then the
RPE who will ensure the electrical isolation is made will complete the application section of the
Isolation/De-isolation Certificate (Electrical). The procedure is described in Section 4.2.3.
3. SAFETY PRECAUTIONS DURING DIVING ACTIVITIES (BSP-71.3.1.3.206.1)
ACTIONS PRIOR TO DIVING OPERATIONS:
1. Confirm requirements of BSP-71.3.1.3.206.1 are fully complied with.
2. Sump to be cleared of all chemical waste prior to the start of operations
and then cleared daily prior to re-validation of this permit.
3. DIVERS DOWN boards to be placed at all access points to the platform
(Main manned Complex only).
4. No additional permit to be issued on the diving complex during diving
operations, without discussion between C.S.R and Authorised Signatory.
5. STL to be informed that no. boats are to approach within 500 metres of the

CSR/Diving Supervisor, the AS is to list them in Box 4.
4. HAZARD IDENTIFICATION AND SPECIAL PRECAUTIONS
3.10.4 Box 5 - Approval of the Permit
The permit requires the APPROVAL of the AS in Box 5 before worksite preparations can proceed.
The term ‘Approval’ means the information in Boxes 1, 2, 3 and 4 has been checked and accepted by
the AS. It does not mean that work can proceed.
When satisfied with the work description and precautions, the AS signs Box 5 to approve the work and
to indicate the period for which the diving work is valid.
If the application is by fax, the AS is to attach the fax to the permit and all copies of the permit are to
be held in the PLANNED section of the permit rack during worksite preparation until the Area

3.11 Briefing of the Workforce - "Toolbox Talk (TBT)"
Safe working requires that both the worksite, and those who will work there have been properly
prepared. Before work starts, the WSS must ensure that those involved with the work are fully aware
of the work content, the potential hazards and the controls in place to prevent their release and their
own responsibilities. This will be done by delivering a Toolbox Talk at the worksite.
Toolbox talks are mandatory for all work. The WSS is to keep written records of toolbox talks
consisting of the date, time, location, permit number for the work, those present and the items
discussed. For more information see BSP-02-Guideline-020 - Toolbox Talks Best Practices.
Topics normally covered in a Toolbox Talk are:
General Worksite Requirements
• outline of activities of others in the area and any resulting hazard(s)
• occasional reminder of access and escape routes, mustering instructions, ESD’s, kill knobs
Specific Worksite Requirements
• objective of the job, targets to be achieved
• permit requirements, precautions, worksite preparations, isolations, gas tests and specific
controls identified on the Hazard Check List
• plan and methods, (equipment and tools) including review of Method Statement or HIP/JSA
• discussion of specific hazards and their controls and recovery measures, encourage open
discussion and questions from the team
• agreement of individual roles and responsibilities
• asking open ended questions (what, who, when, why, where, how) to ensure understanding
• any HSE newsflash or incident relevant to the task
The WSS will use the 3-whats (Appendix 12) concept for a risk assessment as part of the TBT, and is
meant to be carried out before starting any job.
3.12 Supervision of the Worksite
Throughout the work the WSS remains responsible for ensuring that the controls on the permit are
complied with.
Continuous attendance by the WSS at the worksite is required, to ensure that the controls established
by the permit are being maintained. The work must stop when the WSS is not at the worksite. The AA
should make such visits to the site as they considered necessary depending on the potential hazards
associated with the work and depending on the output of the weekly cumulative risk assessment.
When gas testing is required during the course of the work, the AA is to ensure that the Gas Tester is
fully briefed on the work content and controls in place. The Authorised Gas Tester (AGT) has been
appointed by the Asset Holder to carry out gas testing ensure that the controls of the permit are
complied with at all times.

4.1 PTW Certificates
Certificates are attached to the Permit to Work together with the Hazard Check List and other
necessary documents to obtain permission from the AS for preparation(s) required in order to carry
out the work described in Box 1 of the permit e.g. Mechanical/Electrical Isolation/Confined Space
Entry/Hot Work on Live Production Facility.
The certificate is NOT a permit to work and cannot be used without the permit.
The certificates used in the PTW system are listed in Appendix 4.
The colours of certificate copies are:
Worksite - Yellow
Permit Issue Point - Green
Note: An Electrical Isolation Certificate has a white copy that is retained by the SAEP/AEP when
electrical isolations are made.
4.2 Use of Certificates
4.2.1 Multiple Work Permits issued Under a Single Isolation Certificate
It may be necessary to issue more than one permit for work on equipment that has been isolated
either Electrically or Mechanically, for example to carry out separate maintenance work on a pump
and motor set where an Isolation/De-isolation Certificate (Electrical) and/or an Isolation/De-isolation
Certificate (Mechanical) has been issued. In these cases all permits shall be considered as part of the
same work. The following procedure shall be complied with:
1. The initial isolations shall be applied for, carried out and a padlock and electrical caution tag
shall be applied at points of electrical isolation and chain and valve or spade isolation tags
applied at the point of mechanical isolation, and the Isolation/De-isolation Certificates and
Permit shall be issued as appropriate. Refer to Section 3 of this document and Sections 3.5 and
8.9 of BSP-02-Standard-1629 (Module 10) - Electrical Safety Rules.
2. Before the issue of a second or subsequent permit, a second padlock and electrical caution tag
and/or mechanical isolation tag shall be fixed at the points of isolation made for the first permit.
Every permit issued under the authority of an Isolation/De-isolation Certificate shall be
represented at a point of isolation by electrical isolation padlocks and caution tags and/or the
mechanical isolation tags, as appropriate. Where it is not possible to apply a second padlock, a
multiple hasp or other similar device shall be used.
3. The second or subsequent permits are given the same number as that in the task box of the
initial permit. The PIP copy of the Isolation/De-isolation Certificate(s) shall be given the numbers
of all additional permits issued together with copies of all permits attached to the Isolation/Deisolation
Certificate(s) and inserted together into the same slot in the PIP as the original permit.
4. On completion of each individual permit in Box 9a, the electrical isolation padlock and caution
tag and/or chain and mechanical isolation tag associated with the task shall be removed from the
points of isolation and the related permit detached from the PIP copy of the Isolation/De-isolation
Certificates.
5. The physical electrical and/or mechanical isolations shall not be removed until all permits
associated with the relevant Isolation/De-isolation Certificate have been returned to the PIP,
cancelled in Box 9a and removed from attachment to the relevant certificates.

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
4.2.2 Isolation / De-Isolation Certificate (Mechanical)
The Isolation/De-Isolation Certificate (M) is used when any valve or spade isolation is required by the
permit. (Refer to Appendix 4, Figure 7).
BOX 1 - APPLICATION
The WSS completes Box 1 of the Isolation/De-Isolation Certificate (M) entering:
• their name, their contractor/dept., their signature and date of application.
• the installation
• worksite
• equipment to be isolated.
• the number of the originating work permit.
• the number of the Equipment Disjointing Permit if applicable.
The box marked‚ “Work continuing on permit no.” is to be used when a permit validity period has
expired but work is not complete. The certificate can then be transferred to a new permit and the new
permit number entered in the box.
BOX 2 - REASONS FOR ISOLATION
The WSS is to enter the reason for an isolation being required.
The Permit and the Isolation/De-isolation Certificate (M) must then be submitted to the AS.
BOX 3 - DETAILS OF ISOLATION/DE-ISOLATION
The AA is to list all points of isolation, indicating whether a valve is to be opened or closed. The AS also
indicates in Box 3 the location of all points of spade/blank isolation if necessary.
At de-isolation, the AA is to list all points of de-isolation indicating removal of spades/blanks and reinstatement
of valves is necessary.
BOX 4 - ISOLATION
When the permit has been approved, the AS is to authorise the certificate by signing Box 4a.
The AA is responsible for ensuring that the isolations are carried out correctly, using coloured plastic
chain and tie-wraps to hold the chain in place. Each isolation requires an isolation tag to be attached.
These are individually numbered and the AA is to enter the tag number in the relevant column of Box 3.
When the isolations are complete, the AA is to sign Box 4b confirming that the equipment has been
isolated and the isolations are holding. The AA is to initial the ‘Initial checked’ column in Box 4 of the
work permit to confirm isolation have been made.
IF BLEEDING OFF, DRAINING DOWN, VENTING OR ANY OTHER RELEASE OF HYDROCARBON TO
ATMOSPHERE IS REQUIRED THIS MUST BE COMPLETED AND VARIFIED BEFORE AN
EQUIPMENT DISJOINTING PERMIT IS RAISED. ANY CONFLICTING ACTIVITY MUST BE
SUSPENDED PRIOR TO BLEEDING OFF, DRAINING DOWN, VENTING OR ANY OTHER RELEASE
OF HYDROCARBON TO ATMOSPHERE.
The AA is responsible for ensuring that spade tags are written and secured to spade/blanked disjointed
isolation points. When isolation is complete, the WSS signs Box 4c of the certificate.
BOX 5 - DE-ISOLATION
When the WSS has completed the work as described in Box 1 of the Hot/Cold Work Permit that
originated the EDP, and the permit(s) have been cancelled by signatures in Boxes 9a and 9b, the
associated EDP is to be re-accepted and re-authorised providing it remains within the validity period set
by the AS in Box 5. If not, a new EDP must be applied for before disjointing commences.
Box 5a of the Isolation/De-isolation Certificate (M) must be signed by the AS before the WSS can carry
out spade de-isolation.
Permit to Work Procedure – Rev. 4.2 Page 43 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
When all spade de-isolations are complete the WSS is to sign Box 5b. The AA is responsible for
ensuring that the spade isolation tags are returned to the permit issue point and match with the tag
stubs and that the status of the de-isolation is as defined in Box 3, ‘Spade De-Isolated’ column. When
satisfied that spade de-isolation is complete and the disturbed flanges have been pressure tested the AA
is to cancel the Equipment Disjointing Permit as described in Section 3.9.1.
The AA may then remove the valve isolation tags and de-isolate the valves and return the tag stubs to
the permit issue point and match the stubs with the isolation tags and sign Box 5c of the Isolation/De-
Isolation Certificate.
BOX 6 - EXTENDED PERIOD ISOLATION (EPI)
If the WSS is not able to complete the work, and the equipment is to be left isolated, the permit is to be
cancelled using Box 10 and the certificate, isolations and the permit are to be placed in the EPI slot in
the permit rack. The AA is to check to ensure all isolations and tags remain in place.
The AS is to take the certificate to the Senior Operations Supervisor (SOS) who will use Box 6 of the
certificate to confirm the EPI giving the reason and entering the number of the cancelled permit together
with their name, signature, time and the date at which the EPI is implemented.
The worksite and permit issue point certificate(s) are to be placed in the permit rack under EPI together
with the permit to which they are linked.
In order to ensure the EPI remains valid, if the isolation period exceeds 6 months and the isolation is
still required a new Isolation/De-isolation Certificate (Mechanical) shall be issued after confirmation
that all safety controls and notices remain in place.
When the WSS wants to restart the work they are to apply for a new permit. The AS will request the
SOS is to recover the two copies of the original certificate from the EPI slot of the permit rack and reauthorise
the certificate by taking off the EPI by writing in the number of the new permit and giving
their name, signature, time and the date that the EPI has been removed. The AS is to then attach the
certificate to the new permit, and work may proceed once the permit has been approved, accepted and
authorised.
4.2.3 Isolation/De-Isolation Certificate (Electrical)
An Isolation/De-isolation Certificate (E) shall be used as follows:
• where electrical isolation is required as a preparation for work as described in the Box 1 of the
permit
• for long term isolation of electrical circuits.
For further information, refer to BSP-02-Standard-1629 (Module 10) - Electrical Safety Rules (for copy
of certificate reference is made to Appendix 4, Figure 8).
Note: Normally an Isolation/De-isolation certificate (E) is attached to a PTW, however where a
long-term electrical isolation is required but no work controlled by a permit is necessary then
the Electrical Isolation/De-isolation Certificate may be used as a stand-alone document.
In order to ensure the Electrical Isolation remains valid, if the isolation period exceeds 6 months and
the isolation is still required a new Isolation/De-isolation Certificate (Electrical) shall be issued after
confirmation that all safety controls and notices remain in place.

4.2.8 Certificate History Sheet
This certificate (see Appendix 4, Figure 16) is to be attached to a permit when the number of
certificates in use with that permit exceeds the space provided in Box 4 of the permit.
4.2.9 Hot Work on Live Production Facility
This certificate (see Appendix 4, Figure 17) must be used in conjunction with a Hot Work Permit for
Category 1 hot work and must be verified by the AOS. This certification can also be used for
Category 2 and is at SOS discretion.
The number of hot work activities should be determined by the AOS on a case-by-case basis, by
using the RAM and cumulative risk assessment output, i.e. BSP-02-Guideline-022 (HAZID). For each
installation, the SOS is to set a limit on the number of Hot Work Permits that may be authorised at
any one time. This limit should also take into consideration whether the installation is live (SIMOPS)
or shutdown and during night time or hours of darkness and has containment. The limit should be
determined by the weekly cumulative risk assessment, and must be formally recorded at all times in
the PIP.
Work Incompatible with Hot Work
Hot work tasks being undertaken, other than in pressurised non-hazardous areas (habitats), are to
be stopped if any of the following activities are to take place on the same jacket as the hot work site
offshore, or WITHIN 15 METERS ONSHORE.
• Flammable liquids are to be transferred.
Permit to Work Procedure – Rev. 4.2 Page 50 of 133

depressurising Hydrocarbons, breaking containment, pressure testing, pig launching/receiving
etc.
• Any other tasks considered by the AOS to be incompatible with hot work.
4.2.10 Scaffolding
This certificate (see Appendix 4, Figure 18) must be used to approve the erection or dismantling of
multiple scaffolds on one level of an offshore platform, or multiple scaffolds within a defined area
onshore.
4.2.11 Hazard Check List
The electronic BSP PTW Hazard Check List is designed as a Job Hazard Analysis for most work
covered by a permit. Each checklist identifies the hazards and permit controls and provides a check
list for worksite controls that need to be in place. The Hazard Check Lists are provided for two
reasons:
• to ensure that the correct controls are identified for frequently carried out, potentially
hazardous work covered by a permit.
• to provide a means for the WSS/AA/AS to ensure that the correct controls are applied for the
hazards identified and any necessary recovery measures are available should a control(s) failed.
A Hazard Check List is not itself a permit, and cannot be used without being attached to one.
4.2.12 Completing A Hazard Check List
The HCL forms can be downloaded from the HSE/Fountain/Safety Check Page.
• The HCL should be provided by the AS when a permit is to be approved.
BOX 1
In discussion with the WSS, the AS completes Box 1 by striking out those hazards not thought to be
present during the work leaving a list of potential hazards identified.
BOX 2
The AS completes Box 2 by indicating the appropriate Risk Assessment: Low, Medium or High. In
case of Medium or High Risk, the WSS has to attach a method of statement of Hazard identification,
e.g. JSA, HIP, HAZID, etc.
BOX 3
The AS completes Box 3 and transfers appropriate controls from the check list to the attached
permit. Controls not necessary are deleted.
BOX 4
The AS refers to Box 4 and specifies on the attached permit any additional items of PPE identified in
Box 4. PPE not necessary is deleted.
BOX 5
The WSS completes Box 5, the Minimum Health Management Standards - First Aid requirements by
indicating the type of Medical Emergency Response required for the proposed work, in terms of Tier
0, Tier 1 or Tier 2.
BOX 6
The WSS completes Box 6 by verifying the controls indicated in Box 6 at the Worksite. WSS to
confirm controls by putting an initial in the boxes or delete if not applicable.

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
The WSS indicates if any other hazards are present on the location of the proposed work. If
additional hazards are present, the appropriate HCL has to be used and additional controls have to
be added to the permit by the AS.
BOX 7
The AS signs Box 7 of the HCL confirming the discussion has been held with WSS and the Boxes 1,
2, 3, 4, 5 and 6 are completed accordingly.
BOX 8
The WSS will confirm in Box 8 that a TBT will be given to those carrying out the work before it
commences.

5.1 Planning Safe Isolation Boundaries
5.1.1 Purpose of Isolations
The purpose of an isolation is to ensure that a physical barrier is placed between a source of energy
and a place of work. This applies irrespective of the type of work or the nature of the energy. It may
therefore be necessary for mechanical process work to require isolation of electrical power supplies to
pump motors as well as physical isolation by closing of valves and insertion of blinds. It may also be
necessary for electrical work, e.g. repairs to a pump motor, to require mechanical isolation of
equipment potentially hazardous to the person carrying out the work. In order to ensure that energy
sources of all types are prevented from posing a hazard to the place of work, it is necessary first to
plan the establishment of an ‘Isolation Boundary’ between the sources of energy and the work.
It is occasionally necessary to issue more than one permit for work on equipment which has been
isolated, either Electrically or Mechanically, for example to carry out separate maintenance activities
on a pump and motor set where an Isolation/De-isolation Certificate (Electrical) and/or an
Isolation/De-isolation Certificate (Mechanical) has been issued. In these cases the multiple permits
shall be treated as separate work and the additional procedure in Section 4, para.4.2.1 shall be
applied.
5.1.2 Confined Space Entry
Where entry to a process vessel, storage tank or similar confined space is necessary, entry shall not be
authorised until the vessel has been mechanically and if necessary electrically isolated in accordance
with the methods detailed in Confined Spaces i.e. BSP-02-Standard-1645 (Module 07) and Electrical
Safety Rules i.e. BSP-02-Standard-1629 (Module 10).
5.1.3 Work on Process Systems
For work on process systems, isolation in preparation for the work, is to be provided by equipment
disjointing and/or blanking of pipe ends, or by a double block and bleed isolation. Where isolation are
by double block and bleed or by a single valve written approval must be obtained from the Asset
Custodian.
ISOLATION BY EQUIPMENT DISJOINTING
Equipment Disjointing involves the removal of spool pieces, valves etc., the insertion of spades where
possible and the blanking of open flanges if necessary so that the section of the process system to be
worked on is physically separated from other parts of the system. This requires an Equipment
Disjointing Permit to be raised to cover the disjointing.
Blanks fitted to piping, and spades inserted into piping, must be to the same specification and
pressure rating of the piping in which they are fitted.
DOUBLE BLOCK AND BLEED ISOLATION
This requires two separate valves with a bleed connection in between. This is less secure than
isolation by equipment disjointing and spading etc. must be approved by the Asset Custodian.
The block valves must be of a positive closing type such as gate or ball valves. Butterfly or control
valves must not be used for this purpose.
Motor or hydraulically operated valves should be immobilised by isolating their motive power supply.
Check valves of any type must not be used for isolation, they should be removed and blanks fitted if
isolation is required where they are installed.
Permit to Work Procedure – Rev. 4.2 Page 53 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
The isolation valves shall be proven against upstream pressure, with the bleed valves closed, by
observing and noting the build up of pressure between the block valves for one hour using a calibrated
pressure gauge of the correct range. Once the isolation has been proven, the block valves shall be
completely immobilised by chain link so that they cannot be operated without the approval of the
appropriate AS. Bleed lines shall be led to an appropriate location although it must still be possible to
monitor the bleed for leakage.
5.1.4 Work on Non Process Systems
Work on utility systems, e.g. fire mains, domestic gas lines, etc., may be carried out under a single
proven isolation, provided that the system conditions do not exceed 1,000 kPA or 50°C, should the
system conditions exceed 1,000 kPA or 50°C, isolation either by equipment disjointing or double block
and bleed is required.
5.1.5 Work on Systems Involving Electrical Power
Work on electrical systems requires electrical isolation in accordance with either BSP-02-Standard-
1629 (Module 10) - Electrical Safety Rules or BSP-02-Standard-1630 (Module 13) - General Electrical
Safety as appropriate.
Mechanical work on systems to which an electrical supply is connected or present requires electrical
isolation in accordance with the above requirements.
5.2 Recording of Isolations
5.2.1 Requirement for Certificates
MECHANICAL
Isolation/De-Isolation Certificates (M) are to be raised to cover ALL isolations with the exception of the
following:
An isolation certificate is not required if BOTH of the following conditions are met:
• The isolation is to be carried out by a competent person nominated by an AS, for the purpose of
calibration or minor repair/replacement work. Minor repair/replacement work is limited to work
that can be completed without the person doing the work needing to leave the worksite while the
work is being carried out.
• The isolation must not be left in place at the end of the working period.
ELECTRICAL
An Isolation/De-Isolation Certificate (E) is required for all electrical isolation for non-electrical Work.
See Section 4, para. 4.2.3.
Where electrical isolation and/or earthing is required for electrical work of 1,000 volts ac or 1,500 dc
or above an Electrical Work Permit is to be used, see Electrical Safety Rules i.e. BSP-02-Standard-
1629 (Module 10).
5.2.2 Recording at Permit Issue Point
Whenever an Isolation Certificate (E) is used without being attached to a permit, the electrical isolation
is to be identified on the Permit Location Board in the Permit Issue Point, as described in Section 4,
para. 4.2.3.
5.3 Authorisation of Isolations
5.3.1 Mechanical Isolation
Mechanical isolations shall not be carried out unless they have been approved by the appropriate AS.
Permit to Work Procedure – Rev. 4.2 Page 54 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
5.3.2 Electrical Isolation
Electrical isolations shall not be carried out unless they have been approved by an SAEP/AEP.
5.4 Securing of Isolations
5.4.1 Valve Isolation
When a valve or similar device is used as part of an isolation boundary and does not have an internal
valve lock, it is to be secured in the required position by the use of a high visibility plastic chain and
padlock.
5.4.2 Electrical Isolation
The procedure for the securing of electrical isolations is described in BSP-02-Standard-1629 (Module
10) - Electrical Safety Rules.
5.5 Tagging of Isolation Points
All points of isolation, except those that do not require Isolation Certificates (See Para 5.2.1), shall be
identified by the attachment of tags. Different types of tags are used for the isolation of valves, spades
and electrical equipment. Valve and Spade Tags are shown in Appendix 4 Figures 21 and 22,
Electrical Tags in Figure 23. The use of tags for electrical equipment is described in the HSE Standard
Module 10 - Electrical Safety Rules.
The stubs of the Spade and Valve Tags (i.e. the halves not attached to the points of physical isolation)
are to be attached to the Permit Issue Point copy of the Isolation Certificate. When the isolation is
removed, the two halves of each tag are to be compared to confirm that all isolations have been
removed. The stubs are not to leave the Permit Issue Point until the isolation has been removed and
the two halves of the tags checked to ensure de-isolation is complete.
A valve isolation tag label is completed by the AA indicating:
• the equipment isolated
• the isolation certificate number to which the tag(s) are linked
• the name of the AA carrying out the isolation
• the indicator of the AA carrying out the isolation
• the signature of the AA carrying out the isolation
• the date of the isolation
• the AA indicates in the Valve Open/Closed box whether the valve is open or closed by ticking the
relevant box
Where a single valve or other isolating device is used as an isolation for more than one isolation
boundary, a tag label linked to each Isolation Certificate attached to the relevant permit is to be
applied to the valve or device. In this situation it is not necessary to apply additional physical securing
for each Isolation Certificate, but the securing device fitted shall not be removed until the last isolation
applicable to the valve or spade is removed.
A spade isolation tag label is completed by the AA indicating:
• the equipment spade/isolated/blanked
• the isolation certificate number to which the tag(s) are linked
• the name of the AA attaching the spade isolation tag
• the signature of the AA attaching the spade isolation tag
• the date when the spade isolation tag is attached
Permit to Work Procedure – Rev. 4.2 Page 55 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
An electrical isolation tag label is completed by the relevant electrical person (SAEP/AEP) indicating:
• the equipment electrically isolated
• the permit number to which the tag(s) are linked
• the electrical isolation certificate to which the tag are linked
• the reason for isolation
• the number of the safety padlock used to make the isolation(s)
• the name of the SAEP/AEP carrying out the isolation
• the indicator of the SAEP/AEP carrying out the isolation
• the signature of the SAEP/AEP carrying out the isolation
• the date of isolation
• the time of isolation
• the telephone number of the SAEP/AEP who carried out the isolation
5.6 De-Isolation on Completion of Work
5.6.1 Mechanical
Where there is a requirement to remove spades or blanks or to replace spool pieces, and it is necessary
to break the System Integrity, an Equipment Disjointing Permit must be used. If the validity period of
the EDP used to insert the blinds has not been exceeded it may be re-accepted and re-authorised. If the
validity period has been exceeded, a new Equipment Disjointing Permit must be applied for.
Before de-isolation is approved, the AS must:
5.6.2 Electrical
• Ensure all work in connection with the Hot/Cold Work Permit, that required the insertion of
spades/blanks has been completed and the worksite is in a safe condition for de-isolation to
be carried out.
• Agree and identify with the WSS, the spades/blanks to be removed.
• Check the Permit Rack to ensure that de-isolation will not affect other work authorised.
• Check the Permit Location Board for approval.
• If a new EDP has been applied for approve or if the original EDP used validity period has not
been exceeded approve reacceptance and reauthorisation.
• When satisfied that the de-isolation can take place, after the permit has been accepted or reaccepted
by the WSS, the AA is to sign Box 7 or 8b of the Equipment Disjointing Permit,
authorising or re-authorising disjointing and de-isolation to proceed.
• After the de-isolation has been completed, the AA is to remove the Spade Isolation Tag(s), and
return them to the Permit Issue Point and ensure that all Tag stubs match. Should any tags
or tag stubs not be found the AA must confirm that de-isolation has been made by signing
Box 5c on the Mechanical De-isolation Certificate.
Final de-isolation shall not take place until the WSS has declared all the work covered by the electrical
isolation to be complete by signing Box 9a of the permit.
Insert the white copy of the Electrical Isolation Certificate is requested from the SAEP/AEP and the
certificate is re-assembled.
Prior to de-isolation, the WSS shall request clearance to have the electrical equipment de-isolated by
completing Box 7a of the Isolation/De-isolation Certificate.
The AS is then to carry out the following:
Permit to Work Procedure – Rev. 4.2 Page 56 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
a) Check the Permit Location Board to ensure that the removal of the isolation involved will not
affect the isolation boundary for any other work.
b) When satisfied that the work covered by the Electrical Isolation is complete, the AS shall sign
Box 7b of the Isolation/De-isolation Certificate to authorise de-isolation to take place.
The SAEP/AEP shall de-isolate the electrical equipment and complete Box 7c of the Isolation/Deisolation
Certificate and return the certificate to the WSS. The WSS shall return the certificate and the
permit to the permit issue point for cancellation by the AA, who will then complete Box 9b of the
Permit. The white copy of the certificate retained by the SAEP/AEP at isolation will now be reattached
to the worksite and PIP copies of the certificate.
Note: Where de-isolation is required at a remote location, under the control of another AA, a fax copy
of the isolation certificate confirming that the de-isolation is complete is to be sent.
5.6.3 De-isolation for Test
De-isolation of electrical equipment may take place, prior to completion of the work covered by the
electrical isolation for testing purposes only, see also 4.2.3..
Prior to de-isolation for testing:
a) The WSS shall ensure that the permit has been suspended in accordance with the procedure
in Section 3.7.1.
b) The WSS shall request clearance to have the electrical equipment de-isolated by completing
the application in Box 5a of the Isolation/De-isolation Certificate.
The AS shall:
c) Check the Permit Location Board to ensure that the removal of the isolation involved will not
affect the isolation boundary of any other work.
d) When satisfied that the testing work may proceed, the AS shall sign the Clearance Box 5b of
the Isolation/De-Isolation Certificate to approve de-isolation.
The SAEP/AEP shall de-isolate the electrical equipment and remain at the worksite throughout the
testing period until the testing is completed.
Further isolation and de-isolation of the electrical equipment may be carried out until the testing is
confirmed as complete provided that the permit remains suspended.
Once testing is confirmed as complete the SAEP/AEP shall isolate the equipment and complete the
declaration in Box 5c of the Isolation/De-isolation Certificate and return the certificate to the AA.
The permit to which the electrical isolation certificate is attached must be reaccepted and reauthorised
before any further work may commence.
5.7 Extended Period Isolations (EPIs)
5.7.1 Use of Extended Period Isolations
Extended Period Isolations are isolations that are required to remain in place although no work is
being carried out within their boundary. They may be required:
a) Where work has started but is, or is likely to be, suspended for a period exceeding the
Validity Period given by the AS in Box 5 (Cold Work EDP), 5a (Hot Work Permit) for example,
when awaiting spares for a repair.
b) Where an item of equipment becomes redundant and is to be isolated pending its removal or
the provision of a more permanent means of isolation.
Permit to Work Procedure – Rev. 4.2 Page 57 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
5.7.2 Approval of Extended Period Isolation
The procedure for authorising and documenting EPIs is as follows:
a) When work cannot be restarted within the Validity Period given by the AS in Box 5 (Cold Work
EDP), 5a (Hot Work Permit) or when it is decided that de-isolation will be of a permanent
nature the associated Hot Cold or EDP is to be cancelled by the WSS in Box 10a and the AA in
Box 10b.
b) The AA is to indicate in Box 10b of the permit that the work has not been completed, but the
isolation(s) is being retained under the relevant isolation certificate(s) writing in their
number(s).
c) The AS is to confirm an EPI by completing Box 6a of the relevant isolation certificate stating:
• the reason for the isolation.
• the type and number of the Permit being cancelled.
The AS is then to take the Isolation Certificate(s) to the SOS for signature for
confirmation of the EPI.
d) Both copies of the Isolation Certificate and the Isolation Tag Label stubs are to be retained in
the EPI section of the Permit Rack together with the cancelled permit, HCL, tag stubs and
other supporting documents if applicable for audit verification. For Electrical EPI’s, the
WHITE copy of the Electrical Isolation Certificate is to be retained by the SAEP.
e) The pegs on the Permit Location Board relating to the isolation that has been confirmed as an
EPI, are to be changed to GREEN to distinguish them from normal isolations.
f) For Electrical EPIs the keys for the padlocks used to make the isolation are to be retained by
the SAEP/AEP.
g) The PIP Coordinator or AA responsible for the area of the isolation will ensure the site tag(s)
are regularly checked and replaced if necessary if the information on the tag(s) becomes
illegible.
5.7.3 Re-Starting Work within an EPI Boundary
When it becomes possible for the work to restart again within the EPI boundary:
a) The WSS is to apply for a new Permit, entering the number of the Isolation Certificate relevant
to the EPI in Box 4 of the permit. The WSS is to enter the new Permit number in the Work
Continuing under permit number box in Box 1 of the certificate. The isolation certificate(s) is
then attached to the new permit and submitted to the AS for approval.
b) The AS on receiving the application enters the new permit number into Box 6b of the relevant
isolation certificate when referring the certificate to the SOS for signature for confirmation of
the removal of the EPI.
5.8 Master Isolations
5.8.1 Use of Master Isolations
A Master Isolation may be used to establish isolation boundaries for major shutdowns so that a
number of tasks can be undertaken within a single boundary. This reduces the complexity of isolation
documentation, but requires careful control to ensure that isolations are not removed prematurely.
The number of Master Isolations applied should be kept to a minimum to reduce the number of valves
forming part of more than one boundary, and hence requiring multiple tag labels.
Permit to Work Procedure – Rev. 4.2 Page 58 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
5.8.2 Master Isolations for Shutdowns
The process of carrying out Master Isolations for a shutdown is to be as follows:
1. Plan the Isolation
The required isolation boundary is to be planned and marked-up on appropriate Isolation drawings
and a Spading Plan developed. Each isolation point should be given a Unique Identifying Number.
2. Complete the Master Isolation Control Certificates and identify Valve Isolation Tags
A separate set of Master Isolation Control Certificates (see Section 4, para 4.2.4) is to be produced by
the PIP Coordinator for each Platform, or isolation boundary area. The set needed to cover all
isolation points for that Platform/Area are to be attached to the Work Permit. The top sheet of each set
is to be given an identifying number in the number box at the top right of the Certificate.
The isolations should be written on the Master Isolation Control Certificate Register in the order that
the isolations are to be carried out.
Valve Tags are to be written for all valve isolation points. Only the EQUIPMENT/ISOLATION
CERTIFICATE NUMBER/VALVE OPEN/VALVE CLOSED Sections are to be filled in at this time, the
information written on the Tag being as that detailed in Section 5.5.
The numbers of the Valve Tags are to be entered in the column provided on the Master Isolation
Control Certificate Register.
3. Authorise Master Isolation Process to Start
When satisfied that it is safe for the Master Isolation(s) to commence the AS is to approve the relevant
work permit(s).
NB: If there is a requirement to break the integrity of the System then an Equipment Disjointing Permit
is required. A separate Valve Isolation Certificate is not required for this operation.
4. Carry out Master Isolations (Valves)
Valve Isolation is now to be carried out in the sequence decided by the AS. As each isolation is made,
the AA is to:
• Sign and date the Valve Isolation Tag(s) and Tag Stub(s).
• Secure the Tag to the isolation point.
• Initial the ‘Area Authority Initial’ Box in the Valve Isolation column of the Master Isolation
Control Certificate to verify that isolation.
• On completion of Valve Isolation, return the Master Isolation Control Certificates and tag stub(s)
to the Permit Issue Point.
Where the isolation for a Platform or Area includes isolation points outside of that platform or area (e.g.
on another platform), these are to be included on the Master Isolation Control Certificate. The ‘Area
Authority Initial’ Box is to be initialled by the AA when a copy of the Isolation Certificate from the
remote area has been received stating that the isolation has been carried out. This may be sent from
the remote area by fax.
If a change to the isolation boundary is required, this may be approved by the AS writing the reason
for change in the ‘Description’ column against the appropriate isolation, and by signing it.
When the AA is satisfied that the isolation of all valves involved in the Master Isolation for an
individual Platform or Area is complete, the AA is to sign the ‘Valve Isolation Complete’ Box at the foot
of the Master Isolation Control Certificate.
The set of Master Isolation Control Certificates and tag stub(s), together with the Isolation Drawing(s),
is to be retained in the EPI Section of the Permit Rack for the relevant Platform or Area.
5. Plan Master Isolation (Spading)
Prior to installation of spades requiring breaking of containment, the AS and AA must:
Permit to Work Procedure – Rev. 4.2 Page 59 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
• Ensure all equipment has been drained down and depressurised.
• Ensure all valve isolations are in place and holding.
• Refer to the spading plan and decide the best method and sequence for insertion
spades/blanks.
• Discuss the chosen method with the WSS.
• Ensure an Equipment Disjointing Permit is applied for if the containment is flammable, toxic or
corrosive.
6. Prepare Spade Isolation Tags
Spade tags are to be written for all Spade Isolation points. Only the EQUIPMENT and ISOLATION
CERTIFICATE NUMBER Sections on the tags are to be filled in at this time completing:
• The Equipment Description and Unique Identifier Number for the blind/spade isolation.
NB: If a blind/spade is to be inserted to a valve next to a valve that has already been isolated as part
of the Master Isolation then the same unique identification number may be used.
If the spade is not to be fitted at the valve already isolated then a new unique identifier should be
given.
• The number given to the Master Isolation Control Certificate to be inserted as the ISOLATION
CERTIFICATE NUMBER.
• The numbers of the spade tags are to be entered into the column provided on the Master
Isolation Control Certificate.
7. Authorise Spade Isolation Process to Start
When satisfied that it is safe for the Spade Isolations to commence, the WSS is to accept the approved
Equipment Disjointing Permit in Box 6 and blank/spade isolation may proceed after the AA has
authorised the permit in Box 7.
8. Carry out Master Isolation (Spades)
Blank/spade Isolation is now to be carried out in the sequence decided and agreed by the AS and AA.
As each blank/spade is fitted the AA is to:
• Sign and date the Spade Isolation Tag and Tag Stub.
• Secure the Tag to the Isolation Point.
• Initial the ‘Area Authority Initial’ Box in the Spade Isolation column of the Master Isolation
Control Certificate.
• Sign the “Spade isolation complete”, the AA signs the “Spade Isolation complete” Box of the
Master Isolation Control Certificate and brings the Master Isolation Control Certificates and
Spading Tag Stub to the PIP on completion of the spade isolation.
The Equipment Disjointing Permit is cancelled in Boxes 9a by the WSS and 9b by the AA.
9. Spade De-Isolate after Shutdown
Before de-isolation can be authorised, the AA is to carry out the following:
• Check the Permit Rack with the PIP Coordinator or the person delegated to maintain the PLB
for the location to ensure that all work being carried out within the isolation boundary has been
completed, or is in a safe condition to allow the de-isolation to commence.
• Check the Permit Rack with the PIP Coordinator or the person delegated to maintain the PLB
for the location for work in other areas not within the isolation boundary to ensure that the deisolation
will not affect other work being carried out.
• Check that no part of the boundary to be de-isolated forms part of the boundary of an isolation
for another area (refer to Section 5, para. 5.5).
Permit to Work Procedure – Rev. 4.2 Page 60 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
The WSS will apply for an Equipment Disjointing Permit and enter the number of the Master Isolation
Control Certificate in Box 4 of the permit. De-isolation is the reverse of the procedure outlined in Steps
1 – 8 above.
When satisfied that the de-isolation process can commence the AS will approve de-isolation by
completing Box 5 of the Equipment Disjointing Permit.
De-isolation may then be carried out in a controlled manner following the sequence decided and agreed
between the AS and the AA. As each spade or blank is removed, the AA is to:
• Remove the Spade Isolation Tag from the isolation point.
• Initial the ‘Area Authority Initial’ Box in the Spade De-isolation column of the Master Isolation
Control Certificate to verify that de-isolation.
• Bring the Spade Tags and Master Isolation Control Certificates back to the Permit Issue Point
and match the tag with the appropriate stubs to confirm that all blanks/spades have been
removed.
• Confirm that the WSS has cancelled the EDP in Box 9a and complete the cancellation by filling
in the relevant details in Box 9b.
• Pressure test disturbed flanges.
When satisfied that the de-isolation(s) are complete, the AA is to initial the ‘Spade De-isolation’ Box of
the Master Isolation Control Certificate.
10. Valve De-Isolation Prior to Start Up
Before valve de-isolation can commence the AS and AA must agree the sequence to de-isolate in a
controlled and safe manner.
When satisfied, the AA may then:
• Remove the Valve Isolation Tag(s) from the Isolation point(s).
• Initial the ‘Area Authority Initial’ Box of the Valve De-isolation column of the Master Isolation
Control Certificate to verify de-isolation.
• Bring the Valve Isolation Tags and Master Isolation Control Certificates back to the Permit Issue
Point and match the tags with the appropriate stubs to confirm that all valves have been deisolated.
The YELLOW, worksite copy of the Master Isolation Control Certificates is to be archived with the
appropriate Permits in the Permit Archive. The GREEN PIP copy is to be retained as a Spade Register
by the PIP for future reference.

6.1 Permit Issue Point Control
There are 4 main types of Permit Issue Point.
Type Description / Comment Examples
1 These are the most straightforward, where the AS has
ready access to the AA and the Worksite.
2 This type requires the AS to either travel to the Worksite
to approve the permit and attached documents, or send
the permits and attached documents after approval with
the AA when the permit is to be accepted and authorised
for the first time.
Operational Assets
Offshore (normally
manned complexes),
Seria Terminal, New
Gas Compression
Plant (NGCP).
Operational Assets
Offshore Field Areas
and Onshore
Engineering Support
Because of the distance between the PIP and the
Worksite, and when the AA does not return directly to
the PIP after acceptance and authorisation of the work
for which the permit was issued, the white copy of the
permit is kept in the PIP Permit Rack to maintain
visibility of work underway. As the permit is accepted,
authorised and suspended at the worksite, the PIP is
informed and the white copy is moved to the appropriate
section of the rack.
3 This type delegates the responsibility for co-ordination of
permit work to the AA on site. As for all permits, the
approval is carried out by the AS. The permit is then
taken to the PIP controlling the area where the work is to
take place.
The permit is accepted and authorised at the site by the
WSS and AA. Further re-acceptance and reauthorisation
after suspension is carried out locally by
the WSS and the AA for the location at which the work is
taking place.

4 These are at the office of the department responsible for
the work. In order to coordinate a number of
simultaneous tasks, it is necessary to setup a PIP at a
site office to keep track of work underway at any
particular location. The PIP board displays the Plot Plan
of the location and the work is identified by the coloured
disc of the permit being applied.

6.2 Display of Permits and Isolations
BSP-02-Procedure-1622
A structured display showing the status of all Permits and Isolations for the area covered by the PIP
will be maintained within the PIP by the PIP Coordinator or a person delegated to do so.
The purpose of the display is:
a) To identify work under way clearly to AS(s) and AA(s) so that any potential conflicting work can be
avoided.
b) To identify to all users of the PIP what equipment is isolated and therefore not available for use.
c) Notification of variation control.
The Display is made up of two parts:
1) The Permit Rack.
2) Permit Location Board.
6.2.1 The Permit Rack
The permit rack has a number of sections, each one representing an area of an installation or a
platform in a complex. Each section of the rack is subdivided vertically into sections representing the
status of the permit. Into these sections are placed the appropriate copies of permits and supporting
documents. The depth of the rack sections is arranged so that the permit number, description of task
and permit type are visible without removing the complete permit from the rack.
The permit status sections are:
a) Planned Permits for work applied for by the WSS but not yet approved by
the AS.
Permits for work that have been approved by the AS awaiting
worksite preparations to commence.
b) Authorised Permits for which work is in progress.
c) Suspended Permits for which work has started but is not currently in
progress.
d) Extended Period Isolation Permits, Certificates and supporting documents for isolation(s)
retained for an extended period for justifiable reasons.
e) Expired Permits for which the validity period for the work has expired but
which have not yet been cancelled.
The colours of the permit copies visible in the racks provide confirmation of the permit status.
GREEN copy showing
BLUE or RED copy showing
WHITE copy showing
RED or BLUE copy is at the worksite and work is underway. The
permit is AUTHORISED.
The worksite copy is in the rack with the PIP and white copy (if
applicable) and no work is in progress. The work is either
PLANNED or SUSPENDED.
Both worksite and GREEN copies are at the worksite while
preparation are made before the permit can be accepted and
authorised. This gives an indication of possible conflicting work.
NB: A white copy may be used for information purposes if the PIP and worksite copy are at a remotely
located worksite (refer Section 6.1).
Whenever the permit changes status, the permit and its supporting documents are moved to the
appropriate section of the rack, e.g. from PLANNED to AUTHORISED to SUSPENDED, etc.
Permit to Work Procedure – Rev. 4.2 Page 63 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
To highlight when isolations or de-isolations are in progress, a BLUE separator labelled “ISOLATION IN
PROGRESS” and “DE-ISOLATION IN PROGRESS” may be inserted in front of the permit to warn
persons about to start work in the area that this activity is going on.
A similar BROWN separator may be used when “TESTING IS IN PROGRESS”.
6.2.2 The Permit Location Board (PLB/PIP)
Indication of Work Underway
Whenever a permit is authorised or re-authorised and the work is about to start, the exact location
of the worksite will be indicated by a numbered 20mm diameter magnetic disc placed on the Permit
Location Board.
RED
BLUE
PURPLE
for Hot Work

for Equipment Disjointing
Each disc will have its number clearly visible on it and this number will be written in the Task No.
box provided at the top of the permit by the PIP Coordinator or AS, at the first approval of the
permits. At each re-acceptance/re-authorisation, the number linked to the permit will be retained
until the permit is cancelled. The number then becomes re-available for use.
Indication of Plant or Equipment Isolated through Pegging
The Pegging System as described below is MANDATORY for all Permit Issue Points having PIP
Coordinators.
A hole is drilled in the symbol for each item of plant/equipment indicated in the Permit Location
Board, into which is inserted by the PIP Coordinator or AA or the person delegated a coloured peg
when the item is to be isolated or immobilised by an isolation in the system.
A marked-up PEFD must be attached the appropriate permit to indicate valves which require
isolation.
BLUE PEG Valve Isolation/De-isolation. This peg is inserted when the isolation has been
approved and is about to be carried out, AFTER a check has been made to confirm
that the isolation does not conflict with any other isolation already in place.
The blue peg remains in the board until all parts of the isolation are complete, i.e.
Electrical/Instrument/Mechanical.
On de-isolation the blue peg will replace a red peg when the blank/spade has been
removed if appropriate and/or remain in place until the de-isolation is complete.
RED PEG Spade Isolation. The peg is changed from blue to red when the blank/spade
isolations are in place and confirmed in Box 4c of the Mechanical Isolation
Certificate by the WSS.
On de-isolation, the red peg is replaced by the blue peg when the blank/spade is
removed as the first part of the de-isolation commences. Progress of the deisolation
can be readily obtained by reference to the Mechanical Isolation
Certificate in the appropriate section of the rack.
YELLOW PEG
GREEN PEG
Process Override. This peg is inserted at the appropriate location for the override.
Details of the override may be obtained by reference to the Safety System Override
Certificate attached to the relevant permit in the appropriate section of the rack.
Extended Period Isolation. The blue/red peg is changed to green when a permit is
cancelled but the isolation remained in place.

Safety and Emergency System Isolations/Override/Inhibits
When UV, smoke, gas or heat detectors and/or automatic fire suppression systems are isolated,
overridden or inhibited, the fact will be recorded on the Permit Location Board with the appropriate
pictorial marker placed at the location of the isolation/override/inhibit.
Other Displays on the Permit Location Board
Barriers
Scaffolding
Radiography/Testing
/Excavation
Diving
Variation
Wireline
Services/Wellhead
Maintenance
The position of barriers will be indicated by red and white magnetic
strips at the barrier location. This will alert those using the PIP to any
restriction of access and act as a reminder to remove barriers when they
are no longer required.
A pictorial marker is placed at the appropriate location on the Permit
Location Board whenever scaffolding is being erected or dismantled.
When the scaffold is complete and the attached Scafftag has its green
face showing, it is then considered to be part of the facility structure and
the marker may be removed from the Permit Location Board. The
pictorial marker will be displayed during the dismantling of the
scaffolding.
When radiography is in progress, pictorial markers are placed on the
location board to indicate the precise location. When testing of
equipment or excavation is in progress the appropriate pictorial markers
are placed on the affected areas on the location board so that no other
work that could be affected by them is allowed to proceed.
Whenever diving operations are authorised on an offshore platform, the
fact will be highlighted by a pictorial marker on the Permit Location
Board to indicate that platform systems have been isolated for diving in
accordance with the requirements of ROV Operations i.e. BSP-02-
Standard-1652 (Module 18).
Whenever there is a red anomaly highlighted in a Facility Status Report
(FSR), the Asset Holder needs to repair/resolve the anomaly or put a
positive containment in place within 7 days. If Variations are made to
allow for continuous operation, a Variation form is completed detailing
the method of operation of the equipment. A RED pictorial marker with
a ‘V’ is to be displayed on the Permit Location Board to indicate a
variation is in place requiring special controls to be put in place by all
work parties. A copy of the Variation Form including marked-up PEFDs,
Inspection Reports and all the containment measures such as isolation
tags, pictures etc. is displayed in the EPI section of the permit rack.
When routine Wireline or Wellhead Service work has been authorised by
the Asset Holder in accordance with the requirements of Work
Instruction BSP-71.3.1.3.242.0, a pictorial marker is placed on the
Permit Location Board at the location of the work.

7.1 Classification of Areas
7.1.1 Definitions of Hazardous Area Classification
All BSP operating areas have Hazardous Area Classification. The rules applying to hot work depend upon
the classification of the area in which the hot work is to take place.
Zone 0
Zone 1
Zone 0 classification applies to the internals of process vessels, storage tanks and
other similar closed containers. Any source of ignition in a Zone 0 area would,
have the potential to cause a fire or explosion.
Zone 1 classification applies in production areas around process vessels,
wellheads, open drains, vents etc. and in all areas where gas is used as the
pneumatic drive for instruments.
Zone 1 area is an area in which a hazardous atmosphere is likely to occur during
normal operating conditions.
Zone 2
Zone 2 area is an area in which a hazardous atmosphere is not likely to occur
during normal operations and if it does occur, will exist only for a short period.
Non Hazardous Zone All areas not classified as Zone 0, 1 or 2.
7.1.2 Zone 0 and Zone 1 Areas
Hot work (as defined in Section 2.2) is not allowed at any time in Zone 0 or Zone 1 areas. If all alternatives
to hot work as a means of carrying out work in a Zone 0 or Zone 1 area have been considered and ruled out
as impracticable, the following action must be taken:
a) The process system(s) which required the area being classified as Zone 0 or 1 must be shut down,
isolated, depressurised, and gas freed resulting in no hydrocarbon being present. The area may then be
reclassified as Zone 2 or non-hazardous as appropriate, for the duration of the work.
or
b) Where specifically approved in writing by the appropriate AS, a habitat may be used in order to create
an environment within a Zone 1 area, in which hot work may be carried out. The habitat shall be
constructed in such a way that the atmosphere maintained within it will be non-hazardous. This
requires internal pressurisation or other means of preventing gas entry and provision of gas detection
equipment. The entry into and exit from the habitat shall be controlled. A Hot Work Permit may then
be approved and the work carried out subject to the necessary controls specified on the permit.
For offshore work, the controls specified in Work Instruction BSP-71.3.1.3.205.1. Precautions during
Hot Work on Hydrocarbon Production or Processing areas must be taken, including the use of a Hot
Work on Live Production Facility Certificate, where appropriate for Hot Work Category One work.
When re-classifying an area to allow hot work, in order to make the re-classification visible for audit
purposes, the AS should complete Box 2 of the Hot Work Permit as follows:
Put a line through the original classification. Indicate the re-classification by ticking in the appropriate
box and initialling alongside it.
1.
Zone 1
Zone 2
(Initial)
Non-Haz
2. Describe in Box 3 the method of re-classification.
Permit to Work Procedure – Rev. 4.2 Page 67 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
3. Attach the appropriate HAC drawing to the permit and enter the number of the drawing into Box 4
of the permit as a supporting document.
NB: When the permit for the work is cancelled in Box 9a and 9b the temporary re-classification of
the area ceases and the area reverts to its original classification.
7.1.3 Zone 2 Areas
Hot work may be carried out in Zone 2 areas without shutting down production facilities, subject to
the approval of the Asset Custodian. The hot work shall only be approved by the AS when no
alternative means of carrying out essential work are available and stringent controls must be put in
place.
For offshore work, the controls listed in Work Instruction BSP-72-G-007 must be in place, including a
Hot Work on Live Production Facility Certificate where appropriate.
7.2 Hazardous Area Classification Drawings
These detailed drawings show the boundaries of the different zones in each specific operating area.
The drawings are the responsibility of SEN/4 who hold the master copies and arranges periodic review
and updating. Copies of appropriate Hazardous Area Classification Drawings shall be held at each
Permit Issue Point.
When hot work is to be carried out in an area normally classified as Zone 0 or Zone 1 the appropriate
Hazardous Area Classification Drawing must be approved by the AOS. The drawing will be marked-up
to indicate the temporary re-classification of the zones for the duration of the proposed work by the
AS.
In the event of a permanent change of the Hazardous Area Classification Drawing being necessary
approval by SEN/3 is required.

8.1 Actions Following a General Alarm
8.1.1 Stoppage of Work
ALL PERMITS ARE SUSPENDED IMMEDIATELY IN THE EVENT OF A REPORTABLE INCIDENT
All work is to cease immediately following a General Alarm in any facility. The WSS or a person
delegated by the WSS must check to ensure that the worksite has been left in a safe condition, and
take the worksite copy of the permit to the muster point or wherever decided by the installation. The
WSS is to report to the muster checker the fact that they have stopped work and made the worksite
safe.
Where work is such that unplanned stoppage may cause a hazardous condition, the permit is to state
what actions must be taken in the event of an alarm in Box 3.
8.1.2 Re-Starting Work
When the all clear has been given and normal conditions have been re-established, the AOS or SOS or
equivalent will confirm whether or not permits have been suspended as a result of incident. If such an
announcement is made, all permits must be suspended and then re-accepted and re-authorised at the
worksite before work may re-commence.
8.2 Changes to Permits to Work
Once a permit has been authorised, the only change that may be made by AS/AA/WSS are additions
to the controls in the event of extra controls being found necessary during the course of the work.
The additional controls must be written on all copies of the permit.
8.3 Testing After Maintenance
Where work has affected the integrity of a system containing pressurised hazardous gases or liquids, a
pressure test is to be carried out to ensure that the system is safe to be put back into service. The
tests shall be carried out by competent personnel to the satisfaction of the Asset Custodian.
A separate Cold Work Permit is to be applied for approved, accepted and authorised to cover such
pressure testing.
Testing of electrical equipment is to follow the requirements laid down in Electrical Safety Rules i.e.
BSP-02-Standard-1629 (Module 10) and Section 5.6.3.
8.4 Preparation for Equipment Disjointing
If bleeding off, draining down, venting or any other release of hydrocarbon to atmosphere is required
this must be completed and verified before an equipment disjointing permit is raised. Any conflicting
activity must be suspended prior to bleeding off, draining down, venting or any other release of
hydrocarbon to atmosphere. This preparation must be completed before AA approves an EDP.
8.5 Interfaces between Drilling Rigs and Tenders and Fixed Offshore Installations
(Reference is made to the TMS 0004 – Policy and Procedures for Concurrent and Rig Activities,
Sections 6.1 and 6.2)
8.5.1 Manned Platforms
When drilling work is taking place on a manned platform, the well being worked on is handed over to
TSW. TSW must apply to the AS responsible for the Drilling Platform for all work, other than that
related directly to the well.
Permit to Work Procedure – Rev. 4.2 Page 69 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
If any other work is planned on the same Drilling Platform as the handed over well, those intending to
do it must also apply to the AS responsible for the Drilling Platform.
The AS responsible for the Drilling Platform must advise the BSP Drilling Supervisor in writing of any
proposed work on the Drilling Platform. Work must not commence without prior discussion with and
agreement of the DSV. This condition applies to all proposed work.
8.5.2 Satellite Drilling Platforms
For Satellite Drilling Platforms, the Drilling Platform and platforms linked to it by bridge are handed
over to TSW for the duration of the drilling work (CPRA). The DSV becomes the AS and the xOP rep
the AA.
TSW is responsible for the Permit to Work system on Drilling Platforms other than parts of it attached
to the rig or tender (DES) which have been handed over, and all work requests must be directed to the
DSV. Permits for authorisation of work other than on the Drilling Platform shall be handled as follows:
i) For work on attached bridge linked platforms the DSV is the AS and the xOP representative the
AA.
ii)
For work on the jack-ups or tenders or those parts of the jack-up or tender attached to the
Drilling Platform the Tool pusher shall be the AS and a delegated person from the tender or jackup
the AA.
All workers visiting the Drilling Platform, whether bridge linked or not, must report to the DSV at the
drilling tender or jack-up.
All application for permits on the Drilling Platform and attached bridge linked platforms must be made
to the DSV.
All application for permits on the Jack-up or Tender or those part of it attached to the Drilling Platform
must be made to the Tool Pusher.
8.5.3 Hot Work Permit Authorisation – CPPA/CPEMA
CPPA/CPEMA Procedures apply for all hot work on Drilling Platforms, whether or not the platform has
been handed over to TSW. When a platform is handed over to TSW, the procedure must be discussed
and approval obtained from the relevant DSV or Tool Pusher before commencement.
8.5.4 Drilling Rig PTW Systems
Where a contractor owned Drilling Rig operates its own PTW system, a boundary is to be established
between the area in which that system will operate and the area in which the BSP PTW system is to be
operated. Agreement on this boundary should be reached between the relevant AOS and the Drilling
Rig management. The area in which the BSP PTW system applies must include all areas of the fixed
installation and those parts of the Drilling Rig which project into the installation boundary.
It is recommended that all Drilling Rigs and Tenders should use the BSP PTW system when involved in
CPRA operation.
8.6 Non Compliance With Permit to Work Requirements
8.6.1 Guideline on Mandatory Time Out – Relating to Non-Compliance In Permit To Work (PTW)
Requirements
Non-compliance with PTW system requirements is recognised as an issue. A Mandatory Time-Out,
when non-compliance is encountered, is available to effectively deal with non-compliances and to
improve the effectiveness of the system as a management tool for the prevention of incidents.
The duration of forced Time-outs should be long enough for those involved to understand why the job
has been stopped.
Permit to Work Procedure – Rev. 4.2 Page 70 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
A PTW is a vital control barrier in day-to-day management of hazards that have the potential to cause
harm. Breaching of this barrier can result in undesirable incident that can cause harm to People,
Asset, Environment, and Reputation (PAER).
The guideline for the Mandatory Time out is as follows:
1. On identification of any significant or serious non compliance in the work permit system
requirement or application, all work under the control of the PTW concerned must be
suspended immediately and the worksite made safe.
2. All involved in the work must be made fully aware of the reason for the stoppage of the work
before any recommencement is allowed.
3. The length of the Time-Out will depend on how soon all relevant parties directly involved with
the work can be brought together and briefed and made aware of the reason for the Time-Out.
The Time-Out must be conducted in a suitable environment for effective discussion, and should
be away from immediate vicinity of the worksite.
The Mandatory Time-Out is a continuous process to monitor the effectiveness of PTW implementation.
The following are required for review and monitoring purposes:
1. All Mandatory Time-outs are to be highlighted in the respective location or facility daily report.
2. The details of Mandatory Time-Outs will be included in all toolbox talks.
3. The Training Service Provider will brief course participants on the reasons for the Mandatory
Time-Outs.

Permits to Work are MANDATORY for the control of all work that may be potentially hazardous in ALL
Hydrocarbon Processing Assets, which involves breach of containment e.g. routine pigging, and ALL
other Areas or Services where the Asset Holder has decided upon the use of the Permit to Work system
in the Area for which they are the Post Holder. Exceptions to this rule are to be STRICTLY LIMITED.
Examples of work that may normally be carried out without a Permit to Work are:
• Production watch keeping and plant operations including standard checks or sampling of
hydrocarbons, where these tasks are covered by Operating Procedures or Job Instructions.
• Visual Inspection unless that inspection is within a confined space. (Reference HSE Standard 07
Confined Spaces TMSD 1645 page 4 of 15 for examples)
• Helideck operations confined to the landing and take off of helicopters.
• Work carried out on Drilling Tenders, Jack-up Rigs Construction Barges or Work Boats unless
the vessel is located within a 500 metres exclusion zone in which case the BSP PTW System
shall be used.
• Fault finding work required to bring a system back into normal operation following an
unplanned shut down provided that:
• The work is directly supervised by the AA for the area concerned.
• The AS has advised the AA and Control Room personnel, if applicable of any hazards, or
effects on other parts of the process, associated with the work.
• The work does not include fault finding of a non-routine nature that may produce an unsafe
situation.
NB: A permit will be required if the containment of a system is to be breached or work is
required on live electrical equipment.
Once the fault has been identified, a Permit must be applied for in order to carry out any
necessary repair or rectification.
• For ‘Standard’ Wireline and Wellhead maintenance activities. A well handover form may be used
(refer to Appendix 6) and Work Instruction BSP-17.3.1.3.242.0.
The TSW/4 Team Leader who accepted the well on temporary handover from the Asset Holder must be
an appointed WSS. The Asset Unit Supervisor handing over the well to TSW/4 Team Leader must be
an appointed AS with responsibility for the area in which the well is located.
Permits to Work are not normally required for activities carried out by third parties on land, which is
not a BSP operating or controlled area. However, before such work commences, BSP Legal Dept and
the BSP Asset Holder concerned may wish to impose any relevant controls to ensure the safety and
integrity of any BSP Assets that may be affected.

10.1 Definitions
Monitoring of the PTW system consists of regular audits carried out by those responsible for ensuring
the effectiveness of the Permit to Work System.
Auditing is a systematic examination of the operation and effectiveness of the PTW System. Auditing is
performed in accordance with written procedures and checklists, and should concentrate on an
objective evaluation of evidence provided.
A System Review (Level 1 Audit) is an annual examination of the system, carried out after completion
of an annual audit of the PTW System. The review takes into account audit findings, proposals for
change and other relevant information, to assess what changes are necessary to the system to optimise
its effectiveness in meeting its objectives.
10.2 Objectives
The objectives of Monitoring and Audit of the PTW system are:
• To establish that the PTW system is being used as an effective hazard management tool.
• To check that the PTW system is meeting it's stated objectives.
• To provide an opportunity for identifying improvements required to the PTW system and to the
system used for auditing of it.
• To check that compliance with system requirements and controls is being followed.
The objectives of the System Review are:
• To review proposals for change to the PTW system and decide on their implementation.
• To review audit findings, incident reports and other relevant data to identify what improvements
are required in the system.

10.3.1 Level 1 Audit
Level 1 audit are to be carried out annually, and provide a formal independent check on the operation
and effectiveness of the complete Permit to Work System within BSP. The audit will require a team with
a Lead Auditor and is likely to last for several days, plus extra time for preparation and report
production. The audit should examine the PTW system both onshore and offshore to determine its
effectiveness in meeting its stated objectives of hazard identification and management. A formal set of
Terms of Reference in accordance with Activity BSP-02.63, shall be developed and agreed. Before the
start of the audit, the Audit Authority (AD) is to issue a memorandum concerning the audit,
emphasising its importance and stating when it will take place.
The Level 1 audit is to include:
• A check on the frequency, standard and results of Level 2 and Level 3 Audits at those locations
under audit.
• Checks of the PTW system including individual permits at those locations under audit to identify
whether the requirements of the PTW system are being properly applied.
• An examination of PTW training arrangements and their efficiency with reference to the training
master file.
• A review of PTW documentation in place at the location under audit to check for accuracy and
adequacy.
• A review of understanding of the system, and the attitude towards it, by those personnel involved
in its application at the location under audit.
Permit to Work Procedure – Rev. 4.2 Page 74 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
• Examination of arrangements for the appointment of Signatories, Supervisors, PIP Coordinators
and authorised gas Testers to confirm satisfactory appointment controls are in place.
• Examination of the arrangements for system review.
• Any other checks on the system considered necessary by the auditors involved that falls within
the scope of the Terms of Reference of the Level 1 audit.
Any of the standard audit forms may be used to assist in the audit.
The Audit Team should include representatives from HSE and other departments within BSP and from
the Training Service Provider. The majority of the team members shall be experienced in operation and
management of PTW systems and should have completed the PTW Auditors course.
The Audit Authority is to ensure that all corrective actions required by audit reports have been properly
actioned and are subject to regular monitoring.
After each audit, the Audit Authority (AD) is to consider the findings and decide on those actions that
should be entered into FOUNTAIN.
10.3.2 Level 2 - Quarterly Audit
Level 2 audits are to be carried out at intervals not exceeding 3 months using the PTW Level 2 audit
form (refer Appendix 5 – Form B). Results of Level 3 audits should be entered into the Summary Sheet
for Level 2 and 3 audit (refer Appendix 5 – Form A). Any findings or actions can be discussed during
the daily morning meeting for the location concerned and entered into the Fountain Database Action
Item Tracking System for further follow-up and action.
Level 2 audits should examine the operation of the complete PTW system in the area under audit and
will last for at least one working day. Level 2 audits may be carried out by auditor(s) from within the
area, or by auditor(s) from other areas. The HSE Advisor for the area under audit should be invited to
participate in the audit to ensure consistency.
Individual auditors should have knowledge and understanding of hazard management principles and of
PTW system management, gained by having:
• Worked with an established PTW system for a period not less than 1 year,
• Successfully completed the BSP PTW Signatories and Auditors courses.
The Level 2 Audit is to include:
• Checks on the frequency, standard and results of Level 3 Audits.
• Checks on the operation of the PTW System required by the Level 2 Audit Forms (refer Appendix
5 – Form B).
• Any other checks on the system considered necessary by the auditor after reference to previous
Level 2 audits for the area under audit.
The Audit Authority is to ensure that all corrective actions required by audit reports are entered into the
FOUNTAIN database and are properly actioned and subject to regular monitoring.
10.3.3 Level 3 - Monthly Verification
Level 3 verification is to be carried out at intervals not exceeding 4 weeks. They are required to be
carried out in all areas where the PTW System is implemented to verify that the system is working as
intended. These audits provide regular checks on the application of the system and early notification
of any emerging problem areas. They are likely to take no more than an hour to complete and will
normally involve only one auditor.
Permit to Work Procedure – Rev. 4.2 Page 75 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
Level 3 audits are to be carried out using the standard PTW Audit Forms (refer to Appendix 5, Form C).
The Level 3 verification process is particularly valuable as it not only provides a verification of PTW
system performance and application but also, by requiring users to audit the management of the PTW
system for which they are themselves responsible, develops supervisory responsibilities. Findings or
actions can be entered into the FOUNTAIN tracking system and all actions are to be checked and
verified for implementation and close-out during the next Level 3 verification.
10.3.4 Level 4 - Weekly Monitoring
As part of their normal duties, the AS and/or the PIP Coordinator should carry out routine weekly
monitoring of permits on a spot check basis. The PTW Level 4 weekly monitoring checklist is used (refer
to Appendix 5, PTW Level 4 Weekly Monitoring – Form D).
All findings from or actions necessary as a result of the Weekly monitoring are to be discussed during
the daily morning meeting for the location concerned and entered into the PAKAT tracking system.
The Level 4 weekly monitoring is audited as part of Level 3 verification.
10.3.5 Responsibilities of Personnel Involved in the Audit Process
The key persons involved in the audit process are the Auditor and the Audit Authority.
The Auditor is the person responsible for carrying out the audit.
The Audit Authority is the person to whom the audit report is presented and who is responsible for
ensuring that any corrective actions required are made. The role of the Audit Authority is vital in
ensuring that corrective actions are delegated and completed.
Key responsibilities are:
The Auditor
Auditors must prepare properly for and carry out audits effectively and provide an audit report, where
applicable, that sets out the findings of the audit in a concise manner. Auditors are to be aware that
corrective action for non-compliances found during audits is the responsibility of the location being
audited. The carrying out of an Audit does not transfer any responsibility for correcting defects from
the line to the Auditor.
The specific responsibilities of Auditors are:
• To carry out the audit on the time and date agreed with the location being audited.
• To make sufficient time available in order for the audit to be properly conducted.
• To brief those involved in the audit prior to its commencement.
• To concentrate on the objectives of the audit.
• To conduct the audit in an alert, courteous and conscientious manner, carrying out all the checks
required of the audit documentation.
• To submit the report to the Audit Authority within 3 days (Level 3 audit) or 7 days (Level 2 audit).
The Audit Authority
The Audit Authority is to ensure that audits take place in accordance with the audit plan, and is to
ensure sufficient time is made available to analyse and action audit results.
Specific responsibilities of the Audit Authority are:
• To have a clear definition of the Audit Level for the area for which they are the Audit Authority.
• To ensure an audit programme is published.
• To ensure there are sufficient trained and appointed auditors for the area of responsibility.
• To ensure that audit results are analysed and actioned.
• To ensure actions are properly tracked and reviewed.

10.3.6 Audit Numbering
Each Level 2 and Level 3 Audit is to be given a reference number, which is to be written in the space
provided on the Audit forms. Level 1 (annual) audits are referred to simply by the year in which they
were carried out.
The reference number consists of 4 parts:
a) A site or department identifier, e.g. AMPA9.
b) The Audit Level - 2 or 3.
c) The last two digits of the year in which the audit was carried out.
d) The month in which the audit was carried out.
These parts are to be combined into a single identifier of the format shown in the following examples:

10.3.8 Conduct and Level of Audits
To provide a proper assessment of the operation of the PTW system, the audit must be recognised as
important by both Auditors and Auditees. Auditees should show active participation through cooperating
with the Auditors in giving sufficient time for the audit, when required. Auditees should
provide the auditor with sound and reasoned responses to audit questions. The importance of auditing
should be emphasised during HSE Meetings, particularly those where corrective actions are being
reviewed.
Where auditors find isolated minor errors, which are not repeated either by the individual involved or
elsewhere in the area audited, they should be addressed to the individual involved, but should not
constitute non-compliance.
Examples of non-compliance are listed below:
Permit to Work Procedure – Rev. 4.2 Page 77 of 133

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
• Repeated errors by an individual.
• Errors found to be repeated elsewhere in the audit area by individuals.
• A single error that could have led to an unsafe condition.
• Any deliberate failure to comply with the requirements of the PTW system.
In assessing whether an audit finding is a non-compliance requiring corrective action to be taken,
auditors should bear in mind the definition of a non-compliance, which is:
A deviation of unacceptable magnitude from the defined standard which, unless corrected, may
lead to a break down of the system.
10.3.9 Audit Result Categories
Findings for Level 2 audits are categorised using a Risk Assessment Matrix (RAM) (refer Attachment 5,
Appendix 5).
The rating of the audit is given as Good, Fair, Unsatisfactory or Unacceptable.
10.3.10 Audit Programme
An audit programme for Level 2 & 3 audits is to be established as part of each Asst Unit/Service Unit
annual HSE plan and is to form part of the departmental HSE verification matrix. The Level 1 audit is
part of the annual Corporate FAU plan.
Auditors may be from the Asset Holder Department or from other departments working in the area.
Auditors from areas other than the area being audited may be used to provide an independent check.
Level 3 verification should be scheduled on a monthly basis by location and non-compliances presented
at monthly Divisional HSE meetings.
Level 2 audits should be scheduled on a quarterly basis by area, and non-compliances presented as
part of the Departmental HSE meeting quarterly HSE plan verification review.
Level 1 audits will be scheduled by HSE Department as part of the annual corporate HSE Plan. In
order to ensure that all aspects of the PTW system are examined, the Level 1 audit programme should
identify specific issues and/or areas to be examined in the audit.
The programme must ensure that all types of documentation are covered, and that there is a rotation of
types of audit.
10.4 Audit Reports
Reports on Level 2 and Level 3 audits are to be submitted to the Audit Authority (refer Appendix 5 –
Form A).
Audit reports should:
• Be brief concentrating on significant findings from the audit.
• Separate non-compliances from observations.
• Recommend corrective actions and delegate action parties.
• Be presented to the Audit Authority for approval of the recommended actions and delegated action
parties.
• Be accepted and signed by the Audit Authority. The audit report then becomes a formal statement
of actions required.
• Be distributed to all delegated action parties and those involved in the audit.
Distribution of Level 2 Audit and Level 3 Verification Reports is indicated at the foot of the Audit Form
A. The report should be distributed to:
Permit to Work Procedure – Rev. 4.2 Page 78 of 133

BSP-02-Procedure-1622
• Audit Authority
• Delegated Action Parties
• Those involved in the Audit
• The Audit Archive
A copy of all Level 2 audits is to be sent to HSE/4.
10.5 Audit Archiving
Audits for each area audited are to be kept in an archive to ensure that:
• A record of required corrective actions is available.
• Examination of audit records is possible to ensure the audit was correctly carried out and that
the corrective actions have been taken can be made by subsequent auditors.

Module 03 - BSP Permit to Work Procedure
BSP-02-Procedure-1622
c) Expiry of validity period
When the validity period for PTW-1/3/5/FVG-4 has expired, a 3 month grace period is allowed for the
AS/AA/WSS/AGT concerned to attend PTW-5/FVG/4. If the grace period has expired and PTW-5 has
not been attended the AS/AA/WSS concerned must retake PTW-1/2/3 course as appropriate.
Nominations
Line departments wishing to nominate either BSP or contractor employees under their control for permit to
work courses, should in the first instance apply through HLD/311 using the ‘Request for Local Training PTW
Courses’ form. Contractors may apply directly to the Training Service Provider.
Assessment
All PTW Courses include a formal assessment to ensure that those attending the courses have achieved the
required level of competency of the system, as defined in the relevant PTW Course Design Manuals.
The re-appointment process (refer Appendix 8) requires all AS/AA/WSS to attend and demonstrate
competence in a 1-day Refresher (PTW-5) no later than 3 years after attending PTW-1/3/5.
If the required competence level for PTW-5 is not demonstrated by a candidate, the candidate is required to
undergo coaching at the location at which they will be involved with the PTW system to be followed by
attending PTW-2 followed by PTW-1/3 as appropriate. If the candidate cannot demonstrate competence level
required by PTW-2/1/3, it is necessary for them to undergo a further 6 months coaching period at the
location at which they will be involved with the PTW system before re-attending PTW-2/1/3 as appropriate.
If the candidate is still unable to achieve the competence level required they will be subject to deployment to
another position at the same job group or deployment to a position in a lower job group.
Certification
After having demonstrated their competence for the appropriate PTW training course, the successful
candidates will receive individually numbered PTW training certificates. Separate certificates are issued for
each of the six courses. The certificate contains the candidate’s name, I/C or passport number and date of
course attended and expiry date of certificate (where applicable). These details will be entered into a central
record held by HLD (PRISMA) and the Training Service Provider.
Demonstration of Competence
Before appointing a candidate to perform the role for which they have demonstrated competence at the
appropriate course, the AU/SU (Appointing Authority) shall be satisfied that the candidate demonstrates the
sufficient level of competence, knowledge and understanding of the following by:
i. Having sufficient familiarity with the plant within their own area (AS/AA/PIP Coordinator).
ii.
iii.
iv.
Having sufficient knowledge and understanding of other areas of the Installation which may affect
Permits which they will sign (AS/AA/PIP Coordinator).
Having sufficient knowledge and understanding of local Work Instructions, HSE Standards and their
interface with the PTW system, or other appropriate instructions affecting controls to be taken for
particular work (AS/AA/WSS/PIP Coordinator).
Demonstrating competence in the application of HEMP by identifying assessing and controlling
potential hazards on the Installation involved paying particular attention to whose which are
Installation specific (AS/AA/WSS/PIP Coordinator).
v. Having successfully completed the appropriate training courses (AA/AS/WSS/PIP Coordinator).
The candidate for appointment must also demonstrate an adequate understanding of the local environment
in which they are to perform a PTW role.
Recognition of competence can only be decided by the Appointing Authority, who must formally appoint
candidates before they begin to carry out their role within the PTW System (refer Appendix 7).

c) Ordering PTW Documents
PIP Coordinators or persons nominated for management of PIP of respective AU/SU should maintain
adequate copies of all relevant PTW documents used within their own respective locations.
To order copies of PTW documents, a STATIONERY ORDER FORM is raised and sent to HRS/37 together
with a sample of the hard copies of the PTW documents required (to avoid errors and hence delay in delivery).
HRS/37 will raise SAP for ordering as requested.
Attention is drawn to the following points:
1) Training service providers and contractors who require PTW documentation must order through their
Contract Holder.
2) A delivery point must be identified.
3) Queries with regard to difficulties or delays in delivery of any documents should be addressed to HSE
Advisor/Contract Holder.

Findings Assessment and Evaluation Criteria (as per EP2005-0180-SP-02)
IMPLICATIONS SCOPE OF CONCERN EVIDENCE
GOOD
There is no desire/need to take more
or less risk, therefore no additional
actions or resources they are needed to
alter the framework. No follow-up is
required by the next level of
management.
Confined to very few
specific areas. A fit-forpurpose
risk based
control framework is in
place.
The framework is designed to
provide reasonable assurance of
achieving business objectives.
The framework is resourced
appropriately and is operating as
expected/intended.
FAIR
Actions are needed to enhance the
design and/or operation of the control
framework, in order to adjust the level
of risk exposure. The next level of
management should be advised of and
review the actions being taken to
enhance the framework.
Room for overall
enhancement.
A risk-based control framework is
in place. There is scope for
enhancement in the design
and/or operation of the
framework. The expectation is
that on balance the entity will
substantially meet its business
objectives.
UNSATISFACTORY
Actions are needed to improve key
elements of the design and/or
operation of the control framework.
There is a significant gap between the
current level of risk exposure and the
‘target’ level. The next level of
management should monitor the
implementation of agreed actions/
improvements.
Overall cause for
concern from the
standpoint of the
entity.
The risk-based control framework
is in need of improvement. There
are structural weaknesses in the
framework. The exception is that
on balance the entity will
substantially fail to meet its
objectives.
UNACCEPTABLE
The next level of management should
take urgent action to confront the
situation and commit appropriate
resources to immediate resolution of
the weaknesses. Business or Group
senior management should monitor
the implementation of agreed actions/
improvements.
Wide-ranging, may
affect or expose other
parts of Shell.
The risk-based control framework
is not designed and/or not
operating properly. Processes and
systems are seriously deficient of
failing. Drastic and urgent action
is needed to alter the level of
exposure. The exception is that
the entity will not meet its
objectives.

3 Whats
The 3 whats is the simplest form of risk assessment and is meant to be carried out before starting any job. It
is designed so that the workers who are carrying out the job are the people considering the inherent hazards
and risks of that job you're about to do. All you have to do is think about the activities in the task you are
about to undertake and ask yourself these three simple questions;
What can go Wrong ?
Think about what could happen
to you or your colleague in
relation to what you are about to
do at the worksite you are about
to work in
What can cause it to go Wrong ?
Think about the situation, condition,
object or activity that could be the
cause of what could happen to you
or your colleague
What can be done to prevent it ?
Think about what you or your
team could do to prevent an
incident or accident in relation
to what you have identified
could be a problem
