Fatality Assessment and Control Evaluation (FACE) Report for Nebraska: Lineman Electrocuted on Tower

摘要

A 55-year-old senior line technician was killed when a personal protective grounding jumper clamp came loose and came in contact with him, resulting in his electrocution. He and his crew were in the process of aligning suspension clamps which supported shield wires on the electrical transmission towers. He had climbed up an electrical transmission tower to perform the task and had attached his personal protective grounding jumper between the structure (clamp end) and the shield wire (hook end) and was aligning the suspension clamp for the shield wire. The 345,000 volt conductor lines, which are approximately 35 feet below the shield wire, were energized, which was normal for this procedure. The flat faced grounding clamp that was installed on a section of beveled angle iron on the tower structure became disconnected and contacted the victim resulting in his electrocution.
