Summary
An investigation into a welder’s injury during conductor-casing cutting in abandonment and platform removal operations records residual acetylene ignition and momentary unconsciousness. Medical evaluation identified a slight left-wrist sprain. The report discusses hydrocarbon gas checks and a job safety analysis that omitted confined-space hazards, with no district recommendations.
