Lessons Learned
A flammable gas explosion is an analyzed hazard and gas detection/shut off is a safety significant control system that requires a limiting condition for operation (LCO). The rigor of the evaluation of flammable gas systems was inadequate. There was no independent calculation for the hydrogen cylinder and there was no report to document the findings of the evaluation. As a result, incorrect assumptions were made about the acceptability of the hydrogen cylinder. Calculations, independently verified by an engineer, must be included for processes involving a flammable gas and must accompany the hazard control plan for approval.
