Laborer electrocuted when metal work platform became energized in Ohio, August 5, 1988.
NIOSH 1988 Dec; :1-5
The case of a 19 year old male laborer who was electrocuted when a metal work platform on which he was standing penetrated the covering of an overhead crane 440 volt contact conductor and became energized was examined. The victim was employed by a company that had no written safety policy or safety program. He had been employed for 2.5 months and had received only on the job training. He was assisting in reconnecting a security system that had been interrupted during the installation of an overhead door and relocation of another door. In order to reach higher than a ladder allowed, the worker had a forklift raise him up to two I-beams that served as a runway for the overhead traveling crane. The 440 volts energized contact conductors for the crane were attached to one of the beams. A steel basket 4 feet wide, 5 feet long, and 3 feet high was secured to the forks of the lift. The victim got into the basket and was raised to the area in which he wished to work. The operator never watched for clearance between the energized rails and the basket. The energized rail came in contact with the basket. The victim reached out across the side of the basket, contacted the I-beam and completed the circuit. Factors resulting in the accident included the poorly defined work order in the first place, the failure to recognize the potential hazard from the energized crane rails, and a lack of training given to the worker. It is recommended that potential hazards be identified during the job planning phase, and that supervisors ensure that employees understand and follow safe work procedures.
