Abstract: Two employees were unloading shingles onto the roof of a house. One of the employees, who had been with the company since October 9, 1992, was on the bed of their truck controlling the conveyor being used to unload the shingles. The other employee, who had been with the company since June 1, 1993, was standing on the ground by the rear tire of the truck reading invoices. As the first employee was positioning the conveyor, it contacted the middle phase conductor of a 7200-volt overhead power line. The employee on the ground was electrocuted. The other employee, who was thrown clear, received an electric shock and sustained minor burns to his hands. The employees had received training and participated in safety meetings.
