Electrical lineman electrocuted after contacting energized trailer-mounted line tensioner in South Carolina, August 5, 1991.
Morgantown, WV: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, FACE 91-25, 1991 Nov; :1-5
The case of a 27 year old male electrical lineman who was electrocuted when he contacted an energized trailer mounted line tensioner was investigated. The employer was an electrical contractor who specialized in powerline construction, and employed 300 workers, including 150 linemen. The company had a safety director, safety program, safety policy and written safe work procedures. The employer had an ongoing contract with a local electric utility for powerline construction and maintenance. At the time of the accident one crew was stringing new conductors to replace conductors for a three phase, 14,200 volt powerline. The victim and a coworker were working at a grounded, trailer mounted line tensioner. Neither the victim nor the coworker were wearing linemen's gloves or rubber overshoes, even though this was required by the company's safety rules. The first new conductor was being pulled from the tensioner by a pulling rig at the other end of the run. The new conductor unexpectedly began to pull from the tensioner in a jerking motion, causing the new conductor to sway and contact an energized conductor. The victim was in contact with the trailer at the time and was electrocuted. It was recommended that a hazard analysis be performed at each project site prior to initiating work and that hazard information and control measures be communicated during safety meetings. It was also recommended that all workers comply with established safe work procedures that apply to the use of personal protective equipment.
