Abstract
A case study of a worker electrocuted by a 7,200 Volt (V) power line was examined. The accident occurred as workers of an electrical construction company were removing a temporary pole structure used to secure a 7,200V power line while new 150,000V lines were being installed. The new high voltage lines were approximately 30 feet above the existing 7,200V lines. A temporary structure was constructed to prevent the 150,000V lines from falling across the 7,200V lines. The accident occurred when the temporary structure was to be removed. A worker was near the top of the temporary structure in a hydraulic lift bucket and was unwinding the tie line that secured the 7,200V power line to the insulator when the 7,200V line jerked upward. The upward movement of the power line caused the tie line to whip around the left vertical support pole, contacting a ground line that was stapled to the pole from a previous job. Contact with the ground line created an arc and burned through the 7,200V line. The power line fell to the ground landing on a trailer that was hitched to a utility truck. A worker between the trailer and the truck was in contact with a steel anchor rod that protruded from the rear of the truck and was electrocuted. The authors recommend that employers should provide adequate training to supervisors and employees in the recognition, appreciation, and avoidance of hazards and should ensure that employees are proficient in assigned tasks. Management first line supervisory personnel must be responsible for job site safety.
