Master electrician electrocuted while installing fluorescent lighting at a commercial establishment - Maryland.
NIOSH 1999 Jul; :1-5
A 35-year-old male master electrician was electrocuted while stripping insulation from the energized conductors of a metal-clad (MC) cable. The victim was working alone installing wiring in an emergency egress hallway of a commercial establishment and apparently was unaware that the cable was energized with 277 volts. No personal protective equipment was in use while the electrician was working with the live wires. The victim was unobserved during the event, but was believed to be standing on the ground with the cable in one hand and a wire stripper in the other hand. He was found in the poorly illuminated hall by the employee of another subcontractor who came to the victim's work area to borrow a tool. Upon finding the victim on the floor the worker kicked the foot of the victim to see if he was awake and then noticed the arcing at the victim's chest where he was clutching the cable and the wire stripper. The worker hollered to others to deenergize the power and call 911 to activate the emergency medical services. Another worker at the scene shut off the power to the building, came to the aid of the victim, and found him pulseless. No one on the scene knew CPR. Within five minutes the police responded and the officer initiated CPR. The fire department medic unit arrived several minutes later and continued CPR until transporting the victim to the hospital where he was pronounced dead 70 minutes later. The Maryland FACE Investigator concluded that to prevent similar occurrences employers should: 1. Develop, implement, and enforce a lockout/tagout program for electrical circuits or equipment in accordance with the requirements of 29 CFR 1926.417. 2. Ensure that employees do not work alone in situations where a "buddy system" could prevent injury through greater attention to the safety requirements of a job. 3. develop a specific job site safety plan and ensure that care is taken to update the plan when job specifications are changed.
