Summary
A saturation diver removing a blind stab from a subsea skid was pushed backwards by released production gas but remained unharmed. The flash identifies unverified isolation, deviation from procedures, inadequate review of task risks and unused ROV tooling. It highlights change management, procedural hold points and reinforcement of stop-work authority.
