A 27 year old white male working as a tow truck operator for 7 years was electrocuted when the boom he was operating hit a 4800 volt high power transmission line. The victim was attempting to move a junked auto from 2 tiers of junked autos sideways. He was standing on the ground with one hand on the load hook and one on the chain when the boom hit the over head transmission line and he became energized. A co-worker witnessed the incident but was not touching the energized machines/tools. Trained rescue workers were on the scene within minutes of the incident. The worker was pronounced dead approximately 1 hour after the incident. The Wisconsin FACE investigator concluded that, in order to prevent future similar occurrences, the employer should: 1. Implement 29 CFR 1910.180(j): maintain minimum clearance of 10 feet between part(s) of crawler crane(s) or load(s) and power lines. 2. Implement CFR 1910.180(h)(3)(iv): Use cranes as required. It is prohibited to use cranes for a sideways pull on a rigged load in a salvage yard. 3. Implement 29 CFR 1910.180(b)(3): Provide training to crane operators. 4. Survey the work site to identify and address hazards posed by the location of overhead electrical lines. All employees should then be informed of the possible hazards. Work with the power company to move or bury the power line. Set up the yard so that the crane is away from the power lines. Affix safety signs to the equipment to warn the user of potential danger from contact with overhead power lines.
