Request for assistance in preventing electrocutions due to damaged receptacles and connectors.

Morgantown, WV: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, DHHS (NIOSH) Publication No. 87-100, 1986 Oct; :1-6
NIOSH requested assistance in preventing electrocutions resulting from the use of damaged electrical receptacles and connectors. In two accidents, workers died as a result of using damaged connectors. In each case, an assumption was made that because a connector fit into a receptacle, the connection was proper and no hazard existed. In the first case a worker was electrocuted when he touched a loom frame in a textile mill. The frame was energized when an electrical, three prong connector was inserted into a damaged receptacle on the loom so that the ground prong of the plug was inserted into one of the phase terminals. The second death occurred when a welder inserted the male end of an electrical plug on a portable arc welder into a broken female connector of an extension cord, with the ground prong 90 degrees away from the appropriate terminal. The metal case of the welder connector became energized. The investigation indicated that damaged receptacles may permit improper electrical connections. Recommendations to prevent such incidents include the proper utilization of electrical components, hazard recognition, and periodic inspection and maintenance of electrical systems.
