Traction power inspector dies after being electrocuted while doing routine maintenance at a traction power substation in California.
NIOSH 1995 Apr; :1-3
A 42-year-old Caucasian male traction power inspector (the decedent) who worked for a public transportation company was electrocuted while performing routine maintenance at a traction power substation (TPS), for an overhead-powered tram line. According to his supervisor, the decedent was a certified electrician who was familiar with the work being done when he was fatally injured. At the time of the incident, he was visually inspecting surge resistors located on the outside of the substation. He was wearing insulated non-conductive shoes as required by his employer. Two co-workers were working inside the substation when they heard the victim shout that he was burning. The decedent apparently made contact with the surge resistor and received an electrical shock. When the co-workers came to the victim's aid he was on the ground having what they described as spasms. The co-workers also stated that at the same time they heard the decedent scream they also heard the sound of electrical current flow. The feed line on the electrical panel where the decedent was working carried 17,000 volts of electricity. The CA/FACE investigator concluded that in order to prevent similar future occurrences, employers should: 1. have some type of physical barrier and/or enclosure in place between employees and any electrically energized equipment when electrical lockout is not easily accomplished. 2. require that a buddy system be used when employees are working around high voltage electrical equipment. 3. require use of standard operating procedures for work performed in the vicinity of high voltage electrical systems. 4. have prominent, visible warning signs (High Voltage Electricity) in place as a constant reminder to employees of the potential dangers.
