A pre-startup safety review (PSSR) is a critical safety assessment of process equipment and systems before they are put into operation. This comprehensive review ensures that all necessary safety measures are in place, reducing the risk of accidents, injuries, and environmental damage. In this blog, we’ll explore the importance, scope, and benefits of PSSR.

Why Pre-Startup Safety Review Matters
PSSR is essential in various industries, including:
- Chemical processing
- Oil and gas
- Pharmaceuticals
- Petrochemicals
- Power generation
Neglecting PSSR can lead to:
- Accidents and injuries
- Environmental damage
- Equipment damage
- Regulatory non-compliance
- Financial losses
Scope of Pre-Startup Safety Review
A comprehensive PSSR includes:
- Process Hazards Analysis: Identifying potential hazards and recommending mitigation measures.
- Equipment Inspection: Verifying equipment design, installation, and maintenance.
- Safety Instrumented Systems: Ensuring proper function and testing.
- Operating Procedures: Reviewing startup, shutdown, and emergency procedures.
- Training: Ensuring personnel understand safety procedures and equipment operation.
- Mechanical Integrity: Verifying equipment integrity and maintenance schedules.
- Electrical and Instrumentation: Checking electrical and instrumentation systems.
Benefits of Pre-Startup Safety Review
- Enhanced Safety: Identifies and mitigates potential hazards.
- Reduced Risk: Minimises risk of accidents, injuries, and environmental damage.
- Compliance: Ensures regulatory compliance.
- Improved Reliability: Identifies potential equipment issues before startup.
- Cost Savings: Avoids costly repairs and downtime.
- Increased Efficiency: Streamlines startup and operation.
Best Practices for Pre-Startup Safety Review
- Develop a PSSR Procedure: Establish a written procedure outlining scope, responsibilities, and timelines.
- Assemble a Multidisciplinary Team: Include operations, maintenance, safety, and engineering experts.
- Conduct Regular Reviews: Schedule periodic PSSRs for existing equipment and systems.
- Document Findings: Maintain accurate records of PSSR results and actions taken.
- Train Personnel: Ensure personnel understand PSSR findings and recommendations.
Regulatory Requirements
PSSR is mandated by various regulations, including:
- OSHA 29 CFR 1910.119 – Process Safety Management
- EPA 40 CFR 68 – Risk Management Plan
- API RP 750 – Management of Process Hazards
Conclusion
A pre-startup safety review is a critical step in ensuring safe and reliable operations. By conducting a comprehensive PSSR, organisations can identify and mitigate potential hazards, reduce risk, and improve compliance. Remember, PSSR is an ongoing process that requires regular reviews and updates.
