Summary
A worker dismantling emergency shutdown valves on deck sustained a forehead wound when trapped line pressure expelled a gasket. The flash identifies missing pressure checks and monitoring after isolation, alongside water ingress during subsea diving work. Actions included supervised pre-start checks, pressure-checking and venting hold points, and closer line monitoring.
