Line foreman electrocuted while performing routine maintenance at a transformer station in Missouri.
NIOSH 1992 Dec; :1-5
A 46-year-old municipally employed lineman was electrocuted while performing routine maintenance at a transformer station. At the time of the incident the victim and contractor were performing maintenance on an oil disconnect switch. The victim was standing on a six foot fiberglass stepladder and was leaning against the structure (providing a path to ground) when he contacted a 2,400 volt alternating current electrical lead coming out of an oil switch which was thought to be de-energized. The victim broke contact from the source and fell from the ladder to the ground. The MO FACE investigator concluded that, in order to prevent future similar occurrences, employers should: 1. ensure that linemen follow established safe work procedures to de-energize, ground, and verify through testing prior to beginning maintenance and repair operations on electrical transmission lines and equipment. 2. ensure that prior to any work on an electrical system, all involved workers are familiar with the operation of every electrical component. 3. ensure that workers are trained in and follow established safe work procedures relevant to their duties and responsibilities. 4. develop, implement, and enforce a comprehensive safety program which includes worker training in recognizing and avoiding hazards, especially electrical hazards. 5. train employees in cardiopulmonary resuscitation (CPR).
