Apprentice electrician electrocuted, August 23, 1989.
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 89-50, 1990 Jan; :1-7
A 23 year old male apprentice electrician was electrocuted while making a connection for a light fixture in a junction box. The employer was an electrical contractor with 40 employees. The company had a designated part time safety officer, but no written safety program. The victim had worked for the company for about 2 years. Wiring and fixtures were being installed in an office complex. At the time of the incident the victim was wiring in a light fixture at a junction box and was in contact with the gridwork. During the work he received a shock, came down from the fiberglass ladder, asked that the power be cut and collapsed. Coworkers started cardiopulmonary resuscitation immediately. Due to a mixup concerning the location of the accident scene, it was 20 minutes before rescue workers reached the victim. He was pronounced dead at the local hospital. Investigation indicated that two neutral conductors in the same conduit run had been cross wired at a junction box; this allowed electricity to flow from a live circuit through a light fixture to the circuit on which the victim was working. It is recommended that employers limit panel box access to electricians and lock or tag out circuits being actively worked on, that all conductors in the immediate work area be tested by the worker to verify that they are deenergized before starting to work, and that wiring done by apprentice electricians be checked by a journeyman.
