Two heavy equipment mechanics, an 18-year-old male and a 40-year-old male, died when electrocuted while working on a scraper. The scraper was at a construction site parked under a high voltage line. The victims were using the truck-mounted crane on one of their service trucks to assist in replacing the rear differential when the incident occurred. The crane's boom made contact with the high voltage line. The control for the crane was a remote unit electrically wired to the truck. The 18-year-old victim was operating the crane at the time of the incident. The CA/FACE investigator determined that, in order to prevent future occurrences, employers, as part of their Injury and Illness Prevention Program (IIPP), should: 1. Ensure heavy equipment mechanics know the safety and health hazards specific to their job assignments. 2. Ensure all employees perform safety and health inspections prior to starting their job assignments in order to find, eliminate, or control safety and health hazards as well as unsafe working conditions and practices, and to comply fully with the safety and health standards. 3. Ensure all employees are provided with mechanical and physical safeguards to the maximum extent possible in order to perform their job assignments safely. 4. Ensure heavy equipment mechanics are properly trained on machine operation and safety and their achievement of skills is verified through a testing program.
