PreStartup Safety Review (PSSR) |
What is a PSSR?
A Pre-Startup Safety Review (PSSR) aids in the transfer of projects from the construction stage to the operations stage. It ensures that both initial start-ups and start-ups following a major turnaround are carried out safely. In particular, a PSSR aims to confirm that what was built and installed conforms to the original design and standard, and that no hazardous situation was created during construction and commissioning. It is a review of the safety and operability analyses made during the project, and not a technical review.
When should you use a PSSR?
During the analysis stage, the PHA Team leader determines if the project requires a PSSR. If the team leader decides that a PSSR is needed, it is performed after the changes have been made but before the process is restarted. The PSSR should ensure that:
- All proper analyses were performed
- All recommendations and findings were handled responsibly
The PSSR checklist
A PSSR covers not only equipment, but also human factor issues such as operating procedures and training.
The PSSR checklist is a comprehensive checklist and includes:
- Walking through the modified process
- Updating manuals
- Seeing that Quality Control, Quality Assurance and Inspection requirements are met
- Training affected personnel in the new equipment or procedures
