Inc.3853 Losee Road

North Las Vegas, NV 89030

Two employees were on the catwalk of an overhead bridge crane. They were repairing a radio transmitter-receiver for the crane's remote control system. One employee was sitting in front of the crane's bridge control cabinet, tracing and testing the function of

conductors for the crane. The second employee was in front of the crane's

hoist control cabinet.

The employee checking the wiring was sweating profusely from the

heat as he worked in the energized 480-volt cabinet. He

grabbed a 120-volt conductor with needlenose pliers. A portion of the

plastic coating on the handle of the pliers was missing, and the

employee was electrocuted.

The second employee received an electric shock when he removed the first employee from the circuit.

The first employee was

pronounced dead at the North

Vista Hospital.

You must take steps to decrease such hazards in your workplace. Recognize, evaluate, control.
