Coil tester electrocuted while testing insulation on a conduit coil in California.

NIOSH 1994 Sep; :1-3
On February 23, 1994, a 43-year-old white, Hispanic male coil tester (the decedent) died after being electrocuted while testing the insulation on a conduit coil. The decedent was working at a coil testing bench where he was testing the insulation on the wires to make sure it was not defective prior to shipment. There were no barriers between the decedent and the energized coil, and the insulation on the testing device was cracked. Examination of the test equipment revealed that it had been repaired with glass filament strapping tape. The decedent was wearing personal protective equipment (PPE) which included work boots, safety glasses, ear plugs, a back support belt, and leather gloves at the time of the incident. Witnesses stated they heard the decedent groan and saw him fall backward, hitting his head on a conveyor as he fell. They came to his aid and began Cardiopulmonary Resuscitation (CPR) and called 911. Paramedics arrived in a few minutes, continued CPR, and transported the decedent to a local hospital where he was pronounced dead. The CA/FACE investigator concluded that in order to prevent similar future occurrences, employers should: 1. follow the manufacturing guidelines and recommendations for the use of all electrical equipment; 2. maintain all electrical installations in a safe operating condition; 3. have all electrical power panel switches labeled.
