PSM Program Review Checklist
Use this checklist to help determine employer compliance with the Process Safety Management Standard issued by the
Occupational Safety and Health Administration. Please note that the checklist does not include all of the standard’s
requirements and does not reflect all OSHA letters of interpretation or compliance directives in particular
situations.
There are 3 elements to a review of a PSM program:
1. Documentation review – examination of the documentation of the programs required by the standard.
2. Field Inspection & Verification – examination of the physical covered process; its equipment, piping,
instrumentation, procedures, and operation.
3. Interviews – discussions with employees and contractors to determine if the implemented program matches the
program outlined in the documentation.
In order to gather the information needed to audit a PSM program the following questions need to be asked for each PSM
program element
Who What When Where Why How
Who – Who is responsible for developing and implementing each of the program elements?
What – What are the requirements and contents of each program element?
When – When are the required actions for each element completed and when were they required to be
completed?
Where – Where have actions been implemented or changed?
Why – Why have the implementation decisions and priorities been made as recorded in the documentation?
How – How is the program implemented and how is the program’s effectiveness evaluated and improved?
An essential part of verifying program implementation is to audit the flow of information and activities among the
elements. When information in one element is changed or when action takes place in one element that affects other
elements, an auditor/reviewer should examine a sample of the related elements to see if the appropriate changes and
followup actions have taken place.
The following example demonstrates the interrelationship among the elements:
During a routine inspection of equipment (Mechanical Integrity), the maintenance worker discovers a valve that no
longer meets the applicable code and must be changed. Because the type of valve is no longer made, a different type of
valve must be selected and installed (Management of Change). The type of valve selected may mandate different steps
for the operators (Operating Procedures) who will require training and verification in the new procedures (Training).
The rationale for selecting the type of valve must be made available for review by employees and their representatives
(Employee Participation).
When the new valve is installed by the supplier (Contractors), a qualified and safe contractor must be selected to perform
the work (Contractor Management). The work will involve shutting down part of the process (Pre-startup Safety
Review) as well as brazing some of the lines (Safe Work Practices - Hot Work Permit). The employer must review the
response plan (Emergency Planning) to ensure that procedures are adequate for the installation hazards. Although
Management of Change provisions cover interim changes, after the new valve is in place the Process Safety
Information will have to be updated before the (Process Hazard Analysis) is updated or revalidated, to account for
potential hazards associated with the new equipment. Also, inspection and maintenance procedures and training will need
to be updated (Mechanical Integrity).
In summary, 12 PSM elements can be affected by changing one valve. A reviewer/inspector/auditor/compliance officer
would check a representative number of these 11 elements to confirm that the required follow-up activities have been
implemented for the new valve.

Application of PSM Standard to Facility - 1910.119(a)
Does the workplace have any of the following:
A process which involves a chemical at or above the specified threshold quantities listed in Appendix A of
the PSM Standard (attached to checklist); or
A process which involves a flammable liquid or gas [as defined in 1910.1200(c)] on site in one location, in a
quantity of 10,000 pounds (4535.9 kg) or more.
Exemptions:
A threshold quantity of flammable liquids if it is stored in atmospheric tanks or transferred without the
benefit of chilling or refrigeration
Hydrocarbon fuels used solely for workplace consumption as a fuel (e.g., propane used for comfort
heating or gasoline for vehicle refueling.) These fuels cannot be part of a process containing other
highly hazardous chemicals covered by the PSM standard.
Retail facilities.
Oil or gas well drilling or servicing operations.
Normally unoccupied remote facilities.
Note: for determining coverage by the PSM standard, the quantity of flammable liquids stored in
atmospheric tanks may be excluded from the quantity in the covered process pursuant to the “Meer”
Decision.
Important interpretation: June 11, 2007 – OSHA defines “on-site in one location” for PSM to mean that the
standard applies when a threshold quantity of highly hazardous chemical (HHC) exists within an area under
the control of an employer or group of affiliated employers. It also applies to any group of vessels that are
interconnected, or in separate vessels that are close enough in proximity that the HHC could be involved in a
potential catastrophic release.
** IF THE WORKPLACE HAS ANY OF THESE OPERATIONS OR PROCESSES, IT MUST COMPLY
WITH THE PSM STANDARD. **
Examples of industries that may have highly hazardous chemicals and processes covered by the PSM standard:
Industrial production of organics and inorganic
materials
Paints
Pharmaceuticals
Adhesives
Sealants and Fibers
Petrochemical facilities
Paper Mills
Food Processing with Anhydrous Ammonia over
the TQ
Conversion Example
Gallons to lbs conversion = gallons x 8.33 x specific gravity of the liquid = lbs of liquid
Example: Weight of 10,000 gallons of gasoline = 10,000 x 8.33 x 0.739 = 61,559 lbs
