Abstract
Occupational electrocutions caused by damaged receptacles and connectors were discussed. Two Fatal Accident Circumstances and Epidemiology investigations were conducted by NIOSH. The victims tended to be unaware of the dangers associated with the use of damaged receptacles and connectors. However, physically damaged receptacles were described as possibly leading to improper electrical connections. The investigations found that damaged receptacles permitted the ground prong of the connector to contact a live phase terminal. The metal sleeve surrounding the plug of an electric arc welder became energized in one case and the frame of a manufacturing machine became energized in another case. The workers were electrocuted when they simultaneously contacted the energized parts and other parts at ground potential. Because electrical equipment was so often used in the workplace, this potential hazard was considered especially important. Investigations revealed that hazard awareness, the proper usage of electrical components, and the regular safety inspection and maintenance of electrical systems were lacking in many electrocution cases. It was advised that electrical systems comply with the National Electrical Code, OSHA standards, and other criteria. It was further advised that electrical equipment be tested and approved by a recognized testing laboratory. In conclusion, the author recommends that employers implement employee safety training, inspections by qualified professionals, and regular maintenance checks in order to prevent electrocutions in the workplace.
