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 an important 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 prior to 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, including operating procedures and training.

The PSSR checklist is a comprehensive checklist that includes:

• Walking through the modified process
• Updating manuals
• Ensuring Quality Control, Quality Assurance and Inspection requirements are met
• Training affected personnel in the new equipment or procedures

PSSR Facilitation

Dyadem's Engineering Services Division offers a proven track record of helping our clients achieve success in risk mitigation and is committed to providing industry professionals with constructive solutions to meet their risk assessment and risk management objectives. Dyadem can provide the resources that you need to complement your existing project/review team. We will review the project and its goals at the beginning of the project to ensure that it provides the information, analysis and solutions that meet your needs.

Dyadem facilitates your PSSR study in a three-step manner. We will first review the respective process safety information along with the scope and objectives of the project. This is followed by a series of onsite meetings where the facilitator guides the team to identify the hazards associated and assists them in analyzing these scenarios further. Post meeting, the facilitator provides a report that includes all the findings and recommendations of this study.
