Electrician electrocuted in South Carolina, July 19, 1987.
NIOSH 1988 Apr; :1-6
The case of a 29 year old electrician who was electrocuted when he contacted the energized metal frame of an electrically powered foundry stoker that he was attempting to repair was evaluated. The employer was a foundry that smelted iron ore to make ferrous alloys and chrome byproducts. The foundry stokers were modified industrial trucks, each powered by a 40 horsepower electric motor. Power was supplied by a reinforced flexible cord on a retractable overhead reel. The victim began his shift by attempting to repair the No. 5 stoker which had a break in the flexible cord. He was not formally trained to do this work, but he had worked as a maintenance electrician for 7 years. During the repair process the victim inadvertently connected the ground wire to the hot plug terminal, and a hot wire to a ground plug terminal, causing the fuse to blow in the fuse box when the power switch was turned on. The victim replaced the fuse at least six times. Eventually the ground wire melted off the lug where it was connected at the fuse box, interrupting the continuous path to ground and energizing the frame of the stoker. The victim touched the metal foot pedal with his left hand, completing the circuit. The victim died as a result of cardiac arrest due to a low voltage electrocution. A urine drug screen test indicated the presence of marijuana. It is recommended that employees should be adequate trained in the jobs they are asked to undertake. All electrical equipment should be inspected regularly to identify potentially hazardous conditions requiring preventive maintenance.
