Construction Industry Council5 th Progress Report of Committee on Construction Site SafetyPurposeThis paper outlines the main points discussed at the 5 th meeting ofthe Committee on Construction Site Safety held on 2 April 2008. Therecord of attendance is at Appendix A.Issues Discussed2. Members discussed the following items –• Guidelines on Safety of Tower Cranes;• 2 nd Summary Report for Informal Task Force on Working in HotWeather;• 3 rd Summary Report of Informal Task Force on Site Vehicles andMobile Plant;• 4 th Summary Report of Informal Task Force on Permanent SafetyFeatures;• Pay for Safety Scheme (PFSS);• 2nd Summary Report of Informal Task Force on Co-operationwith Property Management Companies; and• work plan.Progress on Matters Arising from 4 th Meeting on 14 December 20073. Members noted the following –(a)Paragraph 25(a) – The Chairman of CIC wrote a letter tothe Secretary for Labour and Welfare on 3 March 2008requesting that favourable consideration be given to bidsfor finance and staff resources (if any) that might be madeby LD for following up on the request made by the

Committee on strengthening the staff establishment oftaking enforcement actions;(b)(c)(d)(e)Paragraph 25(b) – The Chairman of CIC wrote letters toHKIA, HKIE, HKIS and REDA on 3 March 2008requesting support for the PFSS;Paragraph 25(c) – The Chairman of CIC wrote a letter toHKFI on 3 March 2008 requesting HKFI members toconsider whether adoption of PFSS could be taken intoaccount in assessing insurance premium;Paragraph 25(d) – design features for enhancing the safetyof repair and maintenance (R&M) works would bediscussed in latter part of the meeting; andParagraph 25(e) – OSHC’s would make a presentation ofthe 5S method at the meeting of the Informal Task Forceon Behavioural Aspect of Construction Site Safetyscheduled for 16 April 2008.Guidelines on Safety of Tower Cranes4. The Informal Task Force on Safety of Tower Cranes haddeveloped the Guidelines on Safety of Tower Cranes to set out therecommended good practices for enhancing the safety of tower craneoperation. Given that LD would issue suspension notices under section10 of the Occupation Safety and Health Ordinance for non-compliance ofthe guidelines, the guidelines should set out the specific non-complianceswhich could lead to such consequences. LD and HKCA would agree onwhether suitable grace periods should be allowed for theserecommendations that would require considerable lead time forimplementation (such as those on training courses for competent personsand construction workers).5. Members endorsed the guidelines subject to the foregoingcomments and further comments that they would make in writing to theSecretariat before 9 April 2008. The finalized guidelines would bepromulgated after approved by CIC at the 9 th scheduled for 2 May 2008.[Post meeting note – The revised draft incorporating changes proposed atthe meeting and in writing thereafter is at Appendix B.]-2-

2 nd Summary Report for Informal Task Force on Working in HotWeather6. At its 2 nd meeting held on 17 March 2008, the Task Forceconsidered the overall approach for issuing guidelines for safetymeasures for working in hot weather and agreed that the long termdirection should be to link safety measures to thermal stress on workersmeasured by established parameters. Pending further development worksfor facilitating adoption of this approach in Hong Kong, an initial set ofguidelines setting out the basic good practices that could be readilyimplemented would be issued before summer 2008. A study on thermalstress could then be conducted to enable the Task Force to refine theguidelines on the basis of the findings of the research and industryfeedback on the initial guidelines so that a new set of guidelines could bepromulgated before summer 2009.7. Members supported the two-stage approach and proposed that thewearing of sunglasses could affect the vision of workers and shouldtherefore be omitted from the recommended safety measures.8. Members endorsed the guidelines subject to the foregoingcomments and further comments that they would make in writing to theSecretariat before 9 April 2008. The finalized guidelines would bepromulgated after approved by CIC at the 9 th scheduled for 2 May 2008.[Post meeting note – The revised draft incorporating changes proposed atthe meeting and in writing thereafter is at Appendix C.]3 rd Summary Report of Informal Task Force on Site Vehicles andMobile Plant9. At its 3 rd meeting held on 19 March 2008, the Task Forcefinalized the draft of the Guidelines on Safety of Site Vehicles andMobile Plant for providing guidance to contractors and subcontractors onmeasures for enhancing the safety of vehicles and mobile plant operatingon construction sites. Members examined the draft and proposed addinga recommendation that where reversing could not be avoided, it shouldonly take place when a banksman was assigned to guide the driver oroperator or an RVD had been installed to provide the driver or operatorwith clear rear-side views.-3-

10. Members endorsed the guidelines subject to the foregoingcomments and further comments that they would make in writing to theSecretariat before 9 April 2008. The finalized guidelines would bepromulgated after approved by CIC at the 9 th scheduled for 2 May 2008.11. The promulgation of the guidelines would complement a fundingscheme to be launched by LD, OSHC and HKCA whereby a subsidy of$2,500 would be provided to small and medium size companies andindividual owners for installation of reversing video device on sitevehicles. The scheme would cover both vehicles used on site only andvehicles used both on sites and on public road. Given the limited fundsfor the scheme, each company or individual could apply for subsidy forone vehicle only.[Post meeting note – The revised draft incorporating changes proposed atthe meeting and in writing thereafter is at Appendix D.]4 th Summary Report of Informal Task Force on Permanent SafetyFeatures12. The Task Force had identified gondolas, service platforms andcast-in anchorage points as design features to be recommended forincorporation into new buildings for enhancing the safety of R&M worksexecuted on external walls. While gondolas were found to be technicallyfeasible and affordable for residential buildings, the industry support forgondolas would be limited if their enclosures were not exempted fromheight restrictions. The Task Force considered that exemption wasjustified given the limited size of gondola enclosures.13. Similarly, industry support would also be limited for serviceplatforms if they were not exempted from the calculations of accountablegross floor areas (GFA). The Task Force considered that the exemptionwas justified as service platforms would not be included in the saleablearea of residential flats. Members agreed that CIC should be requested towrite to BD, Lands D and Plan D on the subject so as to strengthen theposition of the Task Force would in further discussing with BD, Lands Dand Plan D the possibility of exempting enclosures of gondolas fromheight restrictions and service platforms from calculation of accountableGFA.14. BD would consider developing technical standards for design,construction and maintenance of cast-in anchorage points. When thesestandards were available, the Task Force would deliberate on the-4-

administrative procedures for providing proper maintenance, providingtraining to construction workers on use of anchorage points andprocurement of insurance covers for liabilities resulting from the use ofthe device.15. The Task Force would develop a set of guidelines on gondolas,service platforms and cast-in anchorage points after the completion of thedeliberations on the foregoing issues.Pay for Safety Scheme16. Since the launch of the Safety Partnering Programme by REDAand HKCA in June 2005 to promote the adoption of PFSS in privatesector projects, only 38 sites had joined the scheme. In view of thelimited response, Members explored ways for mandating the adoption ofPFSS through statutory provisions. In this regard, BD advised that as theBuilding Ordinance was primarily concerned with the planning, designand construction of buildings to ensure safety to occupants of thebuildings and members of the public in the vicinity and would not be asuitable platform for mandating the features of the PFSS the objective ofwhich is for safety of workers in the construction works. On the otherhand, under the Factories and Industrial Undertakings (SafetyManagement) Regulation of the Factories and Industrial UndertakingsOrdinance, contractors were required to develop, implement and maintaina safety management system in accordance with the provisions of theregulation and the Code of Practice on Safety Management issued by theCommissioner of Labour in April 2002. The Secretariat would discusswith LD whether the features of PFSS could be enforced throughincorporation into the code of practice.17. Noting that PFSS had been adopted in public sector projects,DEVB was requested to consider extending the scheme to subventedprojects funded under the Head 708 – Capital Subvention and MajorSystem and Equipment of the Capital Works Reserve Fund. TheSecretariat would discuss with HKFI on ways for offering concretefinancial incentive to site adopting PFSS through lower insurancepremium.2 nd Summary Report of Informal Task Force on Co-operation withProperty Management Companies18. The 2 nd meeting of the Task Force was held on 25 March 2008 toconsider initiatives for enhancing the safety of R&M works through-5-

co-operation between LD and property management companies (PMC).On the voluntary referral scheme, a simplified checklist for use by thefrontline staff of PMC in identifying unsafe working conditions (such asomission of anchor bolts for the supporting brackets for truss-outscaffolds, working at height without fall arresting facilities, etc.) and formaking referrals to LD had been prepared and was being circulated tomembers of the Hong Kong Association of Property ManagementCompanies (HKAPMC) for comments. LD would issue a letter toHKAPMC to further solicit supports of its members in keeping a closewatch over hazardous operations.19. LD would circulate for comments by the Task Force a leaflet onthe responsibilities of owners of individual flats and their contractors onthe safety of works executed on their premises. The finalized leafletwould be distributed to building owners through HKAPMC and HomeAffairs Department.Work Plan20. Members considered the proposed work plan of the Committeeprepared by the Secretariat and endorsed the version at Appendix Erevised on the basis of the discussions at the meeting for submission tothe 9 th meeting of CIC scheduled for 2 May 2008.Further Actions21. The following further actions were agreed –(a)(b)the guidelines on safety of tower crane, site vehicles andmobile plant as well as working in hot weather would besubmitted for approval by CIC at the meeting scheduledfor 2 May 2008;CIC would be requested to write to BD, Lands D and PlanD on the exemption of enclosures of gondolas from heightrestrictions and service platforms from calculation ofaccountable GFA so as to strengthen the position of theInformal Task Force on Permanent Safety Features infurther discussing with BD, Lands D and Plan D on thesesubjects;-6-

(h)(i)“Registered Safety Officer” means a person registeredunder regulation 7 of the Factories and IndustrialUndertakings (Safety Officers and Safety Supervisors)Regulations;“Specialist Contractor” means any person who enters intoa contract with a Principal Contractor, or a subcontractorof a Principal Contractor to perform the erection,dismantling and height alteration of tower crane;(j) “Technically Competent Person Grade T5” (TCP T5)means a person whose academic or professionalqualifications or experience of building works or streetworks satisfy the requirements set out in the Code ofPractice for Site Supervision issued by BuildingsDepartment for a particular type of site supervision ormanagement tasks.C. Introduction3. Tower cranes are widely used for conveying of building materialson construction sites. Given that collapse of tower crane could result inserious threats to the safety of site personnel and members of the public,organizations and individual responsible for safety of tower cranes shouldtake appropriate measures to assure their safety.4. The Factories and Industrial Undertakings Ordinance (“FIUO”),the Factories and Industrial Undertakings (Lifting Appliances and LiftingGear) Regulations (“LALGR”) and the Occupational Safety and HealthOrdinance (“OSHO”) impose duties on stake holders to assure the safetyof tower cranes. These are complemented by the Code of Practice on theSafe Use Tower Crane published by the Commissioner for Labour underSection 7A of the FIUO providing practical guidance on selection,operation, erection and dismantling, maintenance, inspection,examination and testing of tower cranes.5. This publication make recommendations on the measures forfurther enhancing the safety of tower cranes based on the good practicessuggested by the concerned industry stakeholders including tower craneowners, specialist contractors and professionals. The Hong KongConstruction Association (HKCA) and the Construction Industry CouncilTraining Academy (CICTA) also contributed on technical andadministrative aspects.

6. While this publication does not have a special legal status, LabourDepartment has indicated that it shall take non-compliances of therecommended practices listed at Annex A into account in consideringserving suspension notices under section 10 of the Occupational Safetyand Health Ordinance (Cap 509) to the concerned Principal Contractorsor Specialist Contractors. For the avoidance of doubt, notwithstandingsuch intention, this publication is issued by CIC for reference by industrystakeholders only and will not constitute professional advice on towercrane operations or any other issues. The parties using this publicationshould therefore seek appropriate advice from their professional advisers.CIC (including its members and employees) will NOT acceptresponsibilities for any consequences resulting from the use of or failureto use this publication.D. Measures for Enhancing Safety of Tower Cranes7. The following groups of measures described in the ensuingparagraphs are recommended for enhancing the safety of tower craneoperations –(a)(b)(c)(d)checking before erection of tower cranes;improvements of site supervision;qualifications and experience of Specialist Contractors;andqualification and experience of Competent Persons andworkmen.E. Checking before Erection of Tower Crane(i)Pre-delivery checking8. The owner of a tower crane should engage a CME to conduct predeliverychecking in accordance with the procedures at Annex B beforethe tower crane is delivered onto the site.9. As stipulated at Annex B, the CME should issue the followingdocuments for the checking –

(a)(b)Report on Pre-Delivery Verification of Components withsample at Appendix B.1 to Annex B; andReport on Pre-Delivery Inspection with sample atAppendix B.2 to Annex B.(ii)Checking of anchorage10. The anchorage of the tower crane should also be certified by anCME using Form 2 prescribed in LALGR before the tower crane may beerected.(iii)Checking of supporting structure11. Before a tower crane is erected, the principal contractor shouldengage a CSE or a TCP T5, with five years of relevant workingexperience to assess the structural integrity of the building structure forsupporting and anchoring of the crane. The CSE or TCP should obtainall necessary information and specifications from the owner of the towercrane for conducting a comprehensive structural analysis includingassessment of the adequacy of the foundation set-up and wall ties inresisting the anticipated loading including wind load.12. The assessment report should be submitted to the PrincipalContractor before concreting of the foundation and supporting structures.(iv)Derrick crane13. Where a derrick crane is used to dismantle a tower crane, theprocedures in paragraphs 8 to 12 above should apply to the derrick crane.In particular, where a derrick crane supported on the roof is used, theadequacy of the roof for supporting the derrick crane should be assessedin the manner set out in paragraph 11 above.F. Improvements of Site Supervision(i) Appointment of supervising engineer14. The principal contractors should appoint in writing a supervisingengineer with the following qualifications, experience and competencesto control, monitor and supervise operations on tower cranes –(a)an engineering degree of relevant discipline;

(b)(c)(d)(e)not less than four years of related working experience;capability in administering the “Hold Points” on criticalparts;capability in communicating with the competent personthroughout the operation; andcapability to conduct a visual inspection on the parts of atower crane to ensure that they are in good working orderbefore commencement of any operations.(ii)Risk Assessment15. The Principal Contractor should arrange to conduct a riskassessment in good time before the commencement of any operation ontower cranes to identify the hazards inherent in the operation and thehazards which could result from adjacent activities. The assessmentshould be conducted by safety professional (e.g. registered safety officers)and Registered Professional Engineer with suitable qualification andexperience in appropriate discipline should be consulted on issues relatedto structural and mechanical stability. The assessment should be updatedimmediately before the start of the operations to take into account anychanges in circumstances.16. Principal contractors should formulate measures for avoiding thehazards identified in risk assessment, or where this is not possible, devisemeasures for minimizing their likelihood of occurrence or mitigating theirconsequences. These measures include –(a)(b)(c)(d)installation of fall protection system for workers workingat height;suspension of work activities within an exclusion zonearound the tower crane until an operation is completed;provision of personal protective equipment such asprotective gloves, ear protectors and reflective vests;sufficient rest breaks;

(e)(f)(g)provision of proper safety training for competent personand workmen engaged in tower crane operations;provision of adequate lighting at inter-floors; andemployment of qualified workmen and competent person.17. Chinese version of the risk assessment report should be madeavailable on site for reference by specialist contractors engaged in towercrane operations.18. The principal contractor and the specialist contractor shouldjointly prepare a method statement in Chinese to define the procedures oftower crane operations covering –(a)(b)(c)(d)(e)(f)all measures for avoiding or mitigating the hazardsidentified in the risk assessment;step-by-step procedures with diagrammatic illustration forconducting the operations with critical hazards and safetyprecautions highlighted by words such as “Danger”,“Caution” and “Hold Points”;procedure and instruction on hold points of critical parts;detailed procedures for avoiding hazards to site personnelworking adjacent to the tower crane;clear statements on the role and tasks of members of theworking crew; andarrangements for effective communication.19. The guidelines for preparing the report for risk assessment are atAnnex C.(iii)Pre-installation checking20. The Principal Contractor should check the availability of thefollowing documents before proceeding with the erection of a towercrane or a derrick crane for dismantling a tower crane –

(a)(b)(c)(d)(e)report on verification of components referred to inparagraph 9(a) above;report on pre-delivery inspection referred to in paragraph9(b) above;Form 2 on checking of anchorage referred to in paragraph10 above;report on assessment of supporting structure referred to inparagraph 11 above; andmaintenance logbook recording the maintenance andinspection history of the crane.(iv)Pre-operation checking21. The principal contractor should make the following documentsavailable before conducting any operation on a tower crane –(a)(b)(c)report of the risk assessment for the operation includingthe method statement;records of the qualification and experience of thesupervising engineer and the competent personresponsible for the operation; andall relevant certificates of test and examination of mobilecranes and derrick cranes used in the operation.22. Copies of risk assessment report (including the method statement)should be distributed to the Specialist Contractor who should be advisedof the estimated duration of the operation and the boundaries of theexclusion zone.(v)Pre-use Verification23. After the completion of each operation, the principal contractorshould engage a CME to conduct a thorough examination and a load testto verify that the tower crane is fit for use. The use of the tower craneshould resume only after satisfactory completion of the verificationprocess.

G. Qualification and Experience of Specialist Contractors24. Principal contractors should only engage competent SpecialistContractors registered on the specialty of “Erection, dismantling andclimbing 1 ” of the Tower Crane trade of the Voluntary SubcontractorRegistration Scheme administered by CIC for tower crane operations.Specialist contractors should possess the relevant experience, sufficienttechnical capability and engage competent person and workmen withappropriate skills and experience.25. A Specialist Contractor should be able to understand the methodstatement for tower crane operations and to explain the details to hisworking crew including a full explanation on the risks associated withimproper working procedures and those safety hints and precautions asoutlined in the warning/attention sections normally marked “Cautions”,“Danger” or “Hold Points”.H. Qualification and Experience of Competent Persons andWorkmen26. Specialist Contractors should employ Competent Persons andworkmen with appropriate qualifications, training and experience forperforming all operations on tower cranes taking into account therequirements set out at Annex D.27. The manufacturer or his local agent should organize and providefamiliarization training on tower cranes to competent persons.I. Summary of Recommendations28. The improvement measures recommended in the foregoingparagraphs are summarized at Annex E together with the implementingparties and timeframe.1 Code 4.1.1

Annex BProcedures for Pre-Delivery CheckingPurposeThis Annex sets out procedures for pre-erection examination oftower cranes.Engagement of CME2. The owner of a tower crane should engage a CME to conduct apre-erection examination of the tower crane before its erection on site.Provision of Documents by the Owner3. The owner should provide the following information to theCME –(a)(b)origins of parts and components - written confirmationthat all parts and components are identical or equivalent tothe tower crane manufacturer’s original equipment partsand components;unique identification of parts and components - uniqueidentification to all main structural parts, motors,gearboxes and braking systems of tower cranes to be usedwhen referring to components in reports for inspection andtesting, and certifications for repairs and modifications.(A sample list is included at Appendix B.1.)(Unique identification will not be required for pins andbolts used containing main structural parts if systems arein place for separating those that have passed nondestructivetests from the others. However, if the cranemanufacturer specifies any limitations on the usage of thepins and bolts (e.g., with useful life dictated by the numberof times that have been in use, etc.), unique identifiersshould be provided.)(c)verification checklist – listing the main componentsmaking up the tower crane to help in verifying that thesemain components conform to the manufacturer’s-1-

specifications;(d)(e)relevant sections from the user manual - to demonstrateconformance of parts and components with themanufacturer’s specifications;maintenance logbook - details of the most recent repairand maintenance work performed on the critical parts aslisted below –(i)(ii)(iii)(iv)(v)Main structural partsMotorsGearboxesBraking systemsSlewing ring mounting boltsExamination by CME(Further details should be provided if requested by theCME.)4. The CME should conduct thorough examination of the criticalparts of a tower crane before it is delivered to the construction sitemaking appropriate reference to the information provided by the owner.A checklist illustrating the possible scope of the examination is atAppendix B.2. As the checklist is for illustration only and is by notmeant to be exhaustive, the CME should examine its applicability andvalidity by making reference to manufacturer’s specifications and manualof the specific tower crane and other relevant information.Non-destructive Tests5. The non-destructive tests on the critical components includingbolts and pins and welded connections should be conducted by qualifiedpersonnel. All bolts and pins (i.e., 100%) used for connection of mainstructural parts should be tested. Items with cracks should be replaced.6. The CME should prescribe the non-destructive tests to beconducted on welded connection based on the result of visual inspectionof critical parts. For critical parts over fifteen years old or ofunconfirmed age, the minimum amount of welded connections to betested shall be 10%. A higher percentage may be specified by the CME-2-

Publication No. xxGuidelines on Site Safety Measuresfor Working in Hot WeatherPurposeThis publication provides guidance to contractors on the measurethat may be taken to protect the safety of site personnel working underhot weather.Introduction2. The hot and humid summers in Hong Kong may lead to workingunder high temperatures on construction sites. It will therefore becrucial to take appropriate safety measures to protect site personnel fromhot weather. Ideally, these measures should be linked to heat stress onworkers (i.e. the physical and physiological reactions of the worker totemperatures that fall outside normal comfort zone) measured byparameters such as Wet Bulb Globe Temperature (WBGT). As furtherdevelopment works are required for adopting such system in Hong Kong,this publication is introduced in the interim to set out some of the goodpractices that may be readily implemented by contractors during thesummer months to enhance the safety of site personnel. CIC willconduct further research on assessment of heat stress and may refine theguidelines in future.(A)Role of client organizations3. Client organizations should render supports to their contractorsfor implementing these guidelines and are encouraged to mandate theiradoption by incorporation into contractual provisions. Clientorganizations should consider taking an equitable approach inincorporating appropriate contractual provisions for granting extensionof time for delays resulting from unusual hot weather and in assessingrequests for extensions of time made for such delays.(B)Role of contractors4. Contractors should establish safe systems of working in hotweather (making reference to the good practices in this publicationwhere appropriate) and provide adequate training, information,instruction and supervision to workers and site supervisors to facilitate

and ensure its adoption. Furthermore, as the guidelines are not intendedto be exhaustive, contractors should determine the safety measures to beimplemented for working in hot weather through the risk assessmentprocedures outlined at Annex A.(C)Role of workers and site supervisors5. Workers and site supervisors should take note and observe theprovisions of the guidelines which are relevant to them (for examplewearing light-coloured clothing).Risks of Working in Hot Weather6. The common heat-related disorders are –- heat syncope (fainting)- heat exhaustion- heat stroke7. Heat syncope occurs when blood pools in the lower parts of thebody causing a temporary reduction in blood supply to the brain andhence a transient loss of consciousness.8. Heat exhaustion results from high body temperature caused byreduction of blood flow and could drive up core body temperature to39 o C. The reduction of blood flow may result from dehydration underhot conditions or extremely fast heartbeat caused by high temperatureand intense physical labour.9. The symptoms of heat exhaustion are –- tiredness, thirst, dizziness- numbness or tingling in fingers and toes- breathlessness, palpitations and low blood pressure- blurred vision, headache, nausea and fainting- clammy skin that may be either pale or flushed- lowering of mental alertness10. Heat stroke occurs when the core body temperature approaches41 o C thus affecting the co-ordination of the nervous system and thermalregulation mechanism. Heat stroke carries a high risk of fatality fromcardiac or respiratory arrest and must be treated as a medical emergency.- 2 -

11. Symptoms of heat stroke includes –- thirst, fatigue and lethargy- nausea and headache- fainting and transient loss of consciousness- clammy skin and paleness- weak and rapid pulse, and uncontrolled muscularcontractions even muscle cramps12. While the symptoms of heat stroke may be similar to other lesssevere heat-related disorders, its onset may be sudden and dramatic.Safety Measures for Working in Hot Weather13. Work arrangements(a)(b)(c)(d)(e)(f)(g)avoid working in hot environment for prolonged periodsof time;take heed of weather report (including very hot weatherwarning);reschedule works to cooler periods (such as early morning)and cooler places (such as sheltered or shaded area) in sofar as possible;schedule works requiring use of personal protectiveequipment (PPE) such as breathing apparatus, apron, longsleeve gloves to cooler times of the day;enable workers to adapt to the hot environment beforetaking on full workload;reduce the physical demand on workers by minimizingmanual work through use of mechanical aids (such astractors, forklifts, electric saws, mechanical hoists);avoid working under direct sunlight. Where this is notpossible –(i)provide shade/shelter where possible on groundlevel or each exposed floor; and- 3 -

(ii)ask workers to apply sunscreen of sun protectionfactor not less than 15 on any exposed skin;(h)avoid working in enclosed areas with poor ventilation.Where this is not possible –(i)(ii)(iii)keep workers away from heat sources or, wherethis is not possible, insulate the heat sources tominimize heat emission;remove hot air from the works area by exhaustpipes or other suitable means; andventilate the works area by using fans or blowers.14. Work break cycle and cool down facilities(a)(b)(c)(d)enable workers to cool down and reduce their exposure tohot environment through taking regular breaks androtating duties and worksites;make arrangements for workers to rest in cool and shadyplace during hot periods;provide shower and washing facilities for washing andexternal cooling; andprovide cooling devices such as cooling fans withatomized water spray.15. Drinks(a)(b)provide sufficient cool (10-15 o C) drinking water at easilyaccessible drinking points;encourage workers to take plenty of water to replenish thebody fluid and electrolytes lost through sweating. Ingeneral, a worker will need to drink at least half a litre ofwater each hour while working under hot weather.However, drinks designed to replace body fluids should beconsumed only in moderation since excess can result inelectrolytes imbalance;- 4 -

(c)(d)prohibit consumption of alcoholic drinks which coulddehydrate the body; andavoid drinks containing caffeine (such as tea or coffee)which are a diuretic and may aggravate loss of body fluids.16. Clothing and protective equipment(a)encourage workers to keep their shirt or other top on andto wear clothing that is –(i)(ii)(iii)(iv)light-coloured (to minimize heat absorption andenhance heat dissipation);loose-fitting (to enhance perspiration. However,clothing that is too loose are not suitable becauseof the risk of entangling in the moving parts ofmachines);made of natural materials (to enhance heatdissipation); andlong-sleeved (to minimize exposure of the skin tosunlight when working outdoors);(b)(c)encourage the use of naturally ventilated helmet toenhance perspiration; andencourage the use of helmet with broad brim to providebetter shade to the face, neck and back.17. Health of workers(a)(b)(c)train supervisors and workers to recognize symptoms ofheat-related disorders;ask workers to inform their supervisors immediately uponsensing or observing any symptoms of heat-relateddisorders; andavoid assigning workers who may have difficulties incoping with heat to work under hot environment takingadvice of their attending doctors into account;- 5 -

18. First aid procedures and facilities(a)(b)develop first aid and emergency procedures and provideappropriate training on these to site supervisors andworkers through talks and regular drills;provide first aid immediately to any workers who showsymptoms of heat-related disorders following theprocedures at Annex B.- 6 -

Guidelines for Risk Assessment for Heat StressAnnex AIntroductionIn planning and executing construction works, duty holders (i.e.the main contractor or its subcontractor in direct control of anyconstruction works) should assess the risks resulting from hot weather andtake appropriate measures to protect site personnel from heat stressthrough risk assessment procedures outlined below.Risk Assessment Procedures(A)Assessment of Risks2. Duty holders should identify risks that may affect constructionpersonnel, their likelihood of occurrence and their possible consequencestaking into account all relevant factors, including –(a)(b)(c)(d)(e)(f)(g)(h)(i)the capability, skill, experience and age of people doing thework;the nature and location of construction operations;the work practices;the anticipated durations of working;the type of plant, machinery and equipment to be used;findings of inspection of the workplace and directobservation of similar construction works;discussion with workers;records of accidents and “near misses”;advice and literature provided by equipment and materialsuppliers;-7-

PurposePublication xxGuidelines onSafety of Vehicles and Mobile Plant on Construction SiteThis publication provides guidelines to contractors andsubcontractors in direct control of any construction works (duty holder) onmeasures for enhancing the safety of vehicles and mobile plant operatingon construction sites.Introduction2. The increase of fatal accidents caused by site vehicles and mobileplant in recent years has given rise to concerns on striking/trappinghazards posed by site vehicles and mobile plant particularly duringreversing.3. Duty holders are encouraged to take a holistic approach inprotecting site personnel from hazards resulting from site vehicles andmobile plant through proper planning, adoption of safe workingprocedures, providing proper training for construction personnel andinstallation of appropriate safety devices on site vehicles and mobile plant.This publication sets out the good practices on these aspects for referenceby industry stakeholders. For the avoidance of doubt, adoption of thesepractices alone may not necessarily be sufficient for complying with therelevant statutory provisions on site safety including any obligations toundertake risk assessment and provide safe systems of work.Safety Measures4. The following measures may be adopted for enhancing the safetyof operation of site vehicles and mobile plant –(a)(b)(c)risk assessment;design of site layout;reversing video device (RVD);-1-

(d)(e)(f)other reversing safety devices;safe working procedures; andtraining of construction personnel.(A)Risk assessment5. Duty holders are encouraged to conduct risk assessments toidentify the risks resulting from site vehicles and mobile plant, assess theirlikelihood and possible consequences taking into account all relevantcircumstances including –(a)(b)(c)(d)locations of ingress and egress points for vehicles;layout of traffic routes on the site;movements of site vehicles and mobile plant in works areasand loading/unloading areas; andmovement of workers and other personnel within the site.6. Appropriate measures should be taken to deal with the hazardsidentified in the above process giving due consideration to their likelihoodand possible consequences. These measures include –(a)(b)elimination of the risk (such as obviating the need forreversing by providing drive-through circulation routes); orwhere the risks could not be eliminated, mitigate them atsource with engineering controls or minimize the risks withdesigning suitable safe systems of work. For instance,where reversing cannot be avoided the reversing vehicle orplant should be guided by a banksman or equipped withRVD.(B)Design of site layout7. Duty holders should properly design site layout and trafficcirculation routes so as to minimize the hazards resulting from site-2-

vehicles and mobile plant following the guidelines in the followingparagraphs and other relevant statutory provisions and practices.8. Minimizing movements - Movements of vehicles and plant onconstruction sites should be minimized through appropriate measuresincluding –(a)(b)(c)controlling entry of vehicles into site through gates andbarriers;providing parking spaces away from works areas; andlocating loading and unloading areas on the periphery ofconstruction sites.9. Safety of pedestrians – Appropriate facilities should be provided tofacilitate safe movement of personnel within the site including –(a)(b)(c)(d)(e)pedestrian-only routes;clear demarcation of pedestrian routes by barrier;grade-separated pedestrian crossing points;at-grade pedestrian crossing points with facilities (such astraffic light signals) for controlling pedestrian and trafficflows; andwearing of high-visibility safety vests.10. Reversing movements(a)(b)reversing movements should be minimized by providing,where possible, drive-through circulation routes;where reversing is unavoidable, turning heads should beprovided and banksmen should be deployed to guidereversing vehicles and plant where necessary; and-3-

(c)steps should be taken to ensure that banksmen wear highvisibilitysafety vests and use walkie-talkie or similarequipment for effective communication.11. Speed limits(a)(b)speed limits should be imposed on traffic routes througherecting speed limit signs; androad humps or other similar devices should be provided toprevent speeding.(C)Installation of RVD12. Duty holders are encouraged to install RVD to provide drivers andoperators with rear-side views through closed circuit television (CCTV)system with camera mounted on the rear of vehicles and plant to capturethe rear-side view for display on a monitor usually installed in front of thedriver and operator.13. Annex A sets out the findings on the assessment of the need andsuitability for installation of RVD on site vehicles and mobile plantcommonly used on local construction sites which may be summarized asfollows –(a)(b)12 types of vehicles/plant for which installation is notrecommended for various reasons such as vibration whichcould affect the functioning of RVD;27 types of vehicles/plant for which installation isrecommended. Out of these –(i)16 types of vehicles/plant which are licensed tooperate on public roads are covered by theguidelines published by Transport Department onRVD and are not therefore covered by thispublication; and-4-

(ii)11 types of vehicles/plant which are used onconstruction sites only and are therefore covered bythis publication.14. The guidelines for installation of RVD on the types ofvehicles/plant referred to in paragraph 14(b)(ii) above are included atAnnex B.(D)Other reversing safety devices15. RVD may be complemented by other reversing safety devicesincluding –(a)(b)(c)cross view mirror;parking sensor (reading / indicator or sound); andreversing alarm and warning light.(E)Safe working procedures16. Duty holders should formulate safe working procedures in relationto the operation of site vehicles and mobile plant on the basis of theguidelines at Annex C.(F)Training of site personnel17. Apart from basic training, duty holders should also provide thefollowing types of training specific to vehicles and plant –(a)(b)(c)(d)job-specific induction and refresher training to drivers andoperators for safe operation of vehicles and plant;courses on safe operation for managers and supervisors;briefing for drivers, operators and workers on the trafficroutes and rules on site; andjob-specific training for banksmen covering safety rulesand instructions on site traffic and communication system.-5-
