Abstract: An electrician was manipulating an equipment grounding conductor behind an exposed, energized 600-ampere 480-volt bus. The conductor contacted the main terminals of two phases and caused an electrical fault. The employee received an electric shock and sustained severe burns from the ensuing electric arc. He was hospitalized for his injuries. Doctors amputated two fingers on one hand and removed the tendon controlling his thumb. Damage to muscle tissue was extensive. The employer had failed to train the employee and provide and enforce the use of personal protective equipment, including rubber insulating gloves.
