Roofer's helper electrocuted when ladder platform hoist contacts a powerline - South Carolina, June 24, 1992.
Morgantown, WV: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control and Prevention, National Institute for Occupational Safety and Health, FACE 92-24, 1993 Feb; :1-7
A 21 year old roofer's helper was electrocuted as he and a coworker were positioning a metal ladder platform hoist which contacted a powerline. The victim was employed by a small family owned roofing construction company; the company had no formal safety program. The victim had worked for this company for 2 years on a part time basis as a helper. At the jobsite, the workers were removing old roofing material and applying new felt paper to the roof. A 26 foot ladder platform hoist was used to raise heavy loads to rooftop level. The victim and a coworker moved the ladder platform hoist to the other side of the residence. A single phase 7,200 volt overhead powerline ran 24 feet above ground level. The workers stood the hoist upright, leaning it against the edge of the carport roof while the feet were on the ground. Feeling this was not the correct position, they then repositioned it, contacting the overhead powerline. It was recommended that a written safety program be developed, that all jobsites be examined for hazards, that worker training be provided in recognizing and avoiding hazards, and that manufacturers of ladder platform hoists consider using nonconductive materials in these devices.
