Pre-Start-Up Safety Reviews: Checking Before the Machine Runs

Why the last check before start-up matters, and what a practical review covers.

ASN Technology ·

New equipment arrives under schedule pressure. Production wants it running. This is the moment when safety checks are most likely to be shortened. A pre-start-up safety review is a structured pause that confirms the equipment is safe before it is handed to operations.

What the review confirms

That the equipment is installed as designed. That guards, interlocks and emergency stops are fitted and tested. That hazards from energy sources, chemicals and moving parts have been assessed. That operating and maintenance procedures exist. And that the people who will run the equipment have been trained.

Who should take part

The review works best as a joint walk-through by engineering, operations, maintenance and safety. Each function sees different risks. A review done by one person at a desk misses what is visible on the floor.

Handling open points

Not every finding stops the start-up. A practical method is to sort findings into two groups: those that must be closed before start, and those that can be closed within an agreed time with a temporary control in place. Each item needs an owner and a date. The decision to start should be signed by a person with the authority to say no.

Keep the record

The completed checklist, test records and sign-off are valuable evidence for audits and for future changes to the equipment. Store them with the equipment file.
