or handled in each unit?
Possible
Score
a. Is the maximum on-site inventory of each of these chemicals listed? 2
b. Is this information available to operations and maintenance personnel and any
appropriate contract personnel in the unit?
c. Are the hazardous effects, if any, of inadvertent mixing of the various materials
on site clearly stated in the standard operating procedures (SOPs) and
emphasized in operator training programs?
Are quality control procedures in place and practiced to ensure that all identified
materials meet specifications when received and used?
Is up-to-date written information readily available in the unit that:
a. summarizes the process chemistry? 3
b. lists the safe upper and lower limits for such items as temperatures, pressures,
flows, and compositions?
c. states the safety-related consequences of deviations from these limits? 3
Is a block flow diagram or simplified process flow diagram available to aid in the

Does documentation show all equipment in the unit is designed and constructed in
compliance with all applicable codes, standards, and generally accepted good
engineering practices?
Has all existing equipment been identified that was designed and constructed in
accordance with codes, standards, or practices that are no longer in general use?
Has it been documented that the design, maintenance, inspection, and testing of
such equipment will allow it to be operated in a safe manner?
Have written records been compiled for each piece of equipment in the process, and
do they include all of the following?
a. Materials of construction. 1
b. Design codes and standards employed. 1
c. Electrical classification. 1
d. Relief system design and design basis. 1
e. Ventilation system design. 1
f. Safety systems, including interlocks, detection, and suppression systems. 1
Are procedures in place to ensure that each individual with responsibility for
managing the process has a working knowledge of the process safety information
appropriate to his or her responsibilities?
Is a documented compilation of all the above process safety information maintained
at the facility as a reference? The individual elements of the Information may exist in
various forms and locations, but the compilation should confirm the existence and
location of each element.
