Abstract: Two employees were spot welding on a drum decker. One of them picked the welding lead up from the ground and was electrocuted. The welding machine was a 480-volt, single-phase machine, and its plug would not fit the 480-volt, three-phase receptacles in the plant. The plant electrician had removed the single-phase plug and replaced it with a three-phase plug, removing the connection for the equipment grounding conductor in the process. Even though the instructions for the welding machine did not recommend using it in wet conditions, the employees were using it under wet conditions. The employees had been working in a hot, wet area; their clothes were wet; and they were wet. Employees interviewed after the accident stated that people had received electric shocks from the machine before the accident.
