Roofing mechanic trainee electrocuted - South Carolina.
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 92-06, 1992 Jan; :1-6
A 19-year-old roofing mechanic trainee (victim) was electrocuted after he inadvertently contacted an energized service entrance conductor. At the time of the incident, a crew of six workers, including the victim, was performing various tasks on the roof of a warehouse. The victim, in preparing to apply aluminum flashing around the perimeter of the roof, was kneeling on the corner of the roof, taking measurements along the roof's perimeter. Two electrical service entrances were located on the corner of the roof where the victim was working. When the victim completed his measurements and stood up, he contacted one of the energized electrical service entrance conductors (240-volts phase-to-phase) at his chest area. At the same time, his right forearm contacted the grounding wire for the service entrance which provided a path for the electrical current across the victim's chest through his right forearm to ground. Two co-workers knocked the victim away from the service entrance conductors and, without training, attempted CPR care until the local emergency medical service (EMS) arrived. The victim was pronounced dead at the emergency room of the local hospital approximately 25 minutes after the incident occurred. NIOSH investigators concluded that, in order to prevent future similar occurrences, employers should: 1) conduct initial jobsite surveys to identify all hazards associated with each specific jobsite, and develop specific methods of controlling the identified hazards; 2) establish procedures for the protection of employees exposed to electrical hazards and provide worker training in the recognition and avoidance of such hazards; 3) ensure that electrical service entrance conductors are insulated; 4) develop, implement, and enforce a written safety program which includes worker training in recognizing and avoiding hazards, especially electrical hazards; 5) train/certify workers in the use of cardiopulmonary resuscitation (CPR); 6) contact the local utility company to de-energize or insulate energized conductors before the start of work.
