Fatal Accident Circumstances and Epidemiology (FACE) Report: ElectricianApprentice Electrocuted After Contacting a 480-Volt Conductor in South Carolina, June 21, 1993

摘要

A 42-year old male electrician apprentice was electrocuted when he lost hisfooting on a ladder and came in contact with an unguarded energized 480 volt overhead crane contact conductor. At the time of the accident the victim and two coworkers had finished performing maintenance on the hoisting motor of an overhead crane, and the victim had operated the controls inside the cab to move the crane. The victim exited the cab of the crane and started to climb a 7-foot steel ladder attached to the outside of the cab and adjacent to the unguarded energized contact conductors. He lost his footing, and extended his left arm to catch himself, contacting one energized conductor. It is recommended that runway contact conductors should be guarded, and bridge contact conductors should be located or guarded so that persons cannot touch them inadvertently. Employers should identify potential hazards and make appropriate safety interventions. Routine facility surveys should be performed to identify potential and/or existing hazards and develop and implement appropriate intervention measures for these hazards.
