Summary
An investigation examines a condensate flash fire during pipe welding that burned a contract rigger. A leaking block valve allowed pressure and condensate to accumulate behind a plumber’s plug, which ejected. Findings address inadequate isolation, hazard assessment and lockout/tagout, while noting that production remained online.
