Abstract: On March 31, 2003, Employee #1 and coworkers were working on an energized 12-kilovolt power line pole, utilizing an aerial device to make up "pot head" connections on a new, not-yet-energized line. They were using a hydraulic pump, powered by an electric motor, to press on the pot head clamps. The pump had an approximately 18 ft long conductive hose. During the course of their work, this hose contacted the energized power line, which was located below the aerial device. The current was transferred through the hose, up through the pump, and down the extension cord to the generator that was supplying power to the pump. The electric generator was mounted on a utility truck. Employee #1 was standing on the ground next to the utility truck at the time the hose contacted the power line. He received a severe electric shock and burns to his left thigh and foot, for which he was hospitalized. The causal factors of this accident were the employer's failure to ensure that non-conductive hoses were used for hydraulic pumps when they are being used around energized power lines. In addition, the employer failed to inform and train employees on the types of hydraulic hoses that were to be used when performing this type of work.
