When is a Pre-Startup Safety Review performed?

• A. After one year of operation.
• B. Only during external audits.
• C. Optional and not required.
• D. Before startup of a modified or new facility or process.

Answer: (D)

A Pre-Startup Safety Review is a proactive check conducted before bringing a new or modified facility or process online. The main purpose is to confirm that design intent is satisfied and all safety controls are in place and verifiable. It ensures that operating procedures, training, permits, and management of change documentation are complete, that safety systems (such as alarms, interlocks, and emergency plans) function as intended, and that the workforce is prepared to operate safely. By verifying readiness before startup, this review helps prevent incidents that could arise from unaddressed hazards, equipment issues, or inadequate procedures as the system goes live. It’s not something that happens after a period of operation, nor is it limited to external audits, and it’s not optional; it’s a required step to authorize startup of a modified or new facility or process.
