Welder was electrocuted while attempting to connect two power cords.

NIOSH 1993 Jul; :1-3
A 38 year old male welder was electrocuted while in the process of connecting two power cords (440 volts). The victim was working over his shift and was connecting an extension cord into the plug on a roller metal bending machine when he received an electrical shock which knocked him unconscious to the floor. The victim was standing on a dry surface. Both female and male plugs which the victim was attempting to couple were defective. The energized extension cord used was not normally coupled with this machine. The housing for the plugs was metal. One of the defective plugs had been reported by a another worker 1-2 hours before the incident. Company representatives indicated that the foreman had not been notified of the defective equipment. The report of the defect came in at the change of shifts. Despite emergency care and transport by the EMT's to an area hospital the worker was pronounced dead within an hour of the incident. The Wisconsin FACE investigator concluded that, in order to prevent similar occurrences, the following issues should be addressed: 1. Conduct a jobsite survey to identify potential hazards before beginning any job. Remove from service defective equipment. Lock and tag out equipment according to OSHA lockout and tagout requirements. 2. Train workers to recognize safety hazards in their workplace that pertain to their job assignments. In this instance, electrical hazard recognition.
