- A PSM Element
- Overlap with other
PSM elements
- Operations Superintendent.
- Decide if PSSR is needed.
- Determine the level of details for a PSSR.
- Appoint a delegate or PSSR Coordinator/Leader.
- Authorize start-up.
- Sign-off the completion of PSSR.
- Appointed by PSSR Gatekeeper
- To be involved in details
- Contributes in the decision about PSSR team members
- Schedules PSSR meeting(s)
- Facilitates PSSR meeting(s)
- Ensures PSSR forms are completed / signed.
- Advise when the MOC / Project is ready for PSSR.
- Contribute in the decision for PSSR team members.
- Ensure all required pre-work are completed.
- Give an overview of the change / project during PSSR meeting
- Follow up on CRITICAL deficiencies to have them completed
before start-up / commissioning.
Deficiency: A finding which needs to be rectified before a MOC or Project can be considered as complete.
A deficiency which needs to be rectified before putting the new or modified system in service.
A deficiency which is not a prerequisite for start up but it needs to be completed before the MOC or Project can be signed off as complete.
- Follow up on NON-CRITICAL deficiencies to have them completed
before final sign-off of the PSSR.
High Risk PSSR Checklist:
- Documentation
- Training / Communications
- Field Verification
- Participate in PSSR review(s).
- Assess the potential hazards.
- Identify deficiencies.
- Classify deficiencies into CRITICAL and NON-CRITICAL.
- Advise if deficiencies have been properly resolved.

Subject Matter Experts
Question Time!
it is safe to put a new / modified process in service.
Compliance with codes and legal requirements
Completion of Process Hazard Analysis and its rec's
The change or project has been managed through appropriate processes (e.g. MOC process)
PSI documents have been revised as required or new PSI documents have been prepared as needed.
SOP's have been revised or new SOP's have been created.
Adequate training for the workforce
Also, PSSR stakeholders should be trained on how the PSSR process works and their roles and responsibilities.
Risk Based PSSR means when deciding about the following two aspects of PSSR, the level of risks associated with a modified or new process must be taken into consideration:
- Whether or not PSSR is required
- What type of PSSR (what level of details) is more appropriate

Question:
Name 3 bases which are covered by performing PSSR.
Explain the relationship between "PSSR" and:
"PSSR" is a requirement of ...
- Codes and regulatory requiements are met.
How about other PSM elements?
- Change has been managed through MOC.
- Hazard Evaluation has been completed.
- Training
- Technical documents and procedures have been updated / created.
- Personal Safety
- Transportation Safety
- Process Safety
One of the areas which are verified during PSSR is about having adequate training for those who will be operating or maintaining the new or modified process.
Also PSSR stakeholders should be trained.
- All critical construction and installation tasks have been completed.
- PSI
- Workforce has received training.
PSSR team will ensure that PSI documents are properly revised / created to accurately reflect the new or modified processes.
Question:
PSSR is .... for new additions .
What does RISK BASED PSSR mean?
PSSR is required for all 'not-in-kind' changes.
- a must
PSSR should be done when there is a risk for starting up a project.
- a must (if any of the PSI documents is impacted)
- True
Also, level of details for a PSSR depends on the risk ranking for the project.
- False
Question:
Name 3 PSI documents?
If a modification causes change in PSI documents, then ....
- P&ID
Piping Layout and Piping Isometrics are part of the PSI documents.
- MSDS
- Equipment DSH / DWG
- PSSR is a requirement
- Pressure Relief System Design Doc's
- True
- Control Systems Design Doc's
- False
- PSSR is only recommended.
- .....
Question:
If a modification does not cause any changes in PSI documents then ....
Is PSSR required when upgrading the governor system for a turbine?
Can the PSSR Gatekeeper & PSSR Leader be the same person?
- PSSR is not required
Yes
- according to principles of RISK BASED
PSSR it might be wise to perform PSSR
if the risk is significant.
Question:
If the size of a control valve is changed, are we required to perform PSSR? Why?
How can we reduce the review time for a PSSR?
Who makes the final decision about whether or not PSSR is needed for a MOC or Project?
Yes, because it is impacting PSI documents.
(There are risks associated with this change; "RISK BASED PSSR")
(Asset Owner)
- Make sure all the records are
availbe for the review team.
- Make sure PSSR team members
are familiar with the project.
Question:
During PSSR, the team ensures that PHA has been
conducted for the new or modified process and PHA recommendations have been properly addressed.
PSSR team will ensure that PSI documents are properly
revised / created to accurately reflect the new or modified processes.
Not Required
(Based on what we mentioned)
One of the areas which are verified during PSSR is
about having adequate training for those who will be operating or maintaining a new or modified process.

Carbon Steel
Not Required
(Based on what we mentioned)
"Not Always"
Good Candidate:
Operations Team Lead
stop a new or modified process
from being put in service if it is not absolutely safe to do so.
