Abstract
The case of a 33 year old male maintenance supervisor who was killed when he inadvertently contacted an energized conductor (22,000 volts) in a high voltage control cabinet was examined. The victim worked for a company that has been in operation 9 years and used laser equipment for precision cutting, drilling, and welding. Safety orientation was provided to new employees, but a written comprehensive safety program did not exist. The victim was to fix an electrical output problem with one of the lasers. The victim and his assistant told the operator to stop the operation but not to deenergize the equipment. He explained that the problem would be visible once he opened the high voltage control cabinet. The victim opened the cabinet door and slid out a drawer containing conductors. A safety device designed to automatically deenergize the equipment had previously been rendered inoperable. The victim removed a metal precision screwdriver from his pocket to point out the problem area to the assistant. As he pointed, he inadvertently contacted an energized conductor and suffered cardiac arrest due to electrocution. Employers should require that employees follow standard written operating procedures, particularly when around dangerous equipment. Electrical safety devices should never be altered.
