Construction worker electrocuted in North Carolina, September 24, 1987.
NIOSH 1987 Dec; :1-5
The case of an 18 year old construction worker who was electrocuted and two coworkers who received an electrical shock when the 32 foot aluminum extension ladder they were using contacted a 7200 volt overhead power line was examined. The victim worked as a part time construction worker for a small residential commercial contractor. The company had no written safety program at the time of the accident. The employer was contracted to remodel a roof on a two story office building. A fully extended 32 foot aluminum extension ladder was positioned between a three phase 7200 volt overhead power line and the side of the office building. The power line was 27 feet about ground level. The victim and one employee held the ladder as another employee climbed it to locate an area of the roof to store the shingles. The roof proved to be too steep to store the shingles and he began to descend still carrying the shingles on his back. The ladder tipped backward, contacting the power line. The employee on the ladder and one employee stabilizing the ladder were shocked and knocked away from the energized ladder. The victim, gripping the ladder to stabilize it, was electrocuted. Had the site been carefully examined prior to starting work, the hazard presented by the power lines would have been identified. Ladders used near energizer power lines should be made of nonconductive materials. Employees should be trained in cardiopulmonary resuscitation.
