Abstract: An electrician was installing a 277-volt Quantum emergency light (Model No. ELM2) at a facility. The lighting fixture was about 4.3 meters above the concrete floor and was mounted on a horizontal steel purlin. The employee was using a Keller aluminum ladder (Model No. 3532) to gain access to the light. The circuit for the fixture was energized. As the employee was stripping insulation from a conductor feeding the fixture, he contacted the conductor and was electrocuted. Neither the electrical contractor nor the facility had an effective electrical safety-related work practice program in place.
