摘要

A 23-year old male journeyman wireman was electrocuted when he contacted two phases of an energized buss inside a switchhouse at a utility company power facility. He was employed by an electrical contracting company which was one of two contractors installing an emissions control system at the powerplant. Although the contracting company normally used a lockout and tagout procedure, the utility company's tagout only policy was being used. The incident occurred in the facility electrical equipment building where workers were in the final stages of installing electrical components inside a 14 compartment switchhouse. The workers circuit breaker protecting the switchhouse's internal buss was isolated according to the power facility tagout procedures. The victim was wiping down individual compartments. Without the knowledge of the workers, the internal buss had been energized by power facility personnel. He was electrocuted. A coworker was knocked down by the blast, and suffered first degree burns. Another worker was burned trying to extinguish the victim's burning clothing. Recommendations included implementing procedures to control hazardous electrical energy which include both lockout and tagout provisions, providing employees with voltage sensors, and installing hazard warning lights inside electrical equipment enclosures to warn of inadvertent energizing.
