Abstract: Employee #1, who was a lineman, and a coworker, who was a truck driver helper, were installing a new service drop to a house. Employee #1 was elevated in the bucket tying new wire and the coworker was standing behind the truck. Employee #1 said that the coworker hollered, "Look out," but the next thing he knew, the truck was going down the driveway with him still in the elevated bucket. When the truck came to a stop against the house, Employee #1 was thrown approximately 52 ft. He sustained a fractured arm and leg and a bruised liver and kidney, for which he was hospitalized. A subsequent investigation revealed that the coworker apparently had not properly set the brakes on the truck. The employer has a good training program, a full-time safety director, and a disciplinary program. Employee #1's belt and lanyard were in the truck.
