Summary
An investigation examines a flash fire that severely burnt a rigger’s arms during removal of a plumber’s plug from a high-pressure vent line. Premature spool installation allowed gas to accumulate. Findings address ineffective valve isolation, failure to verify pressure and construction miscommunication; welding ground clamps were identified as a possible ignition source.
