On September 30, 1988, a 33 year old male steel mill adjuster was electrocuted when he contacted a ventilation fan with a damaged power cord. The facility at which the incident occurred was a steel manufacturing facility employing 534 workers. The adjuster was seen standing on a metal stairway immediately in front of a large, 480 volt ventilation fan, with a startled look on his face; when he was seen in the same position a short time later, another worker deenergized the circuit for the fan. Cardiopulmonary resuscitation was begun immediately, and the victim was transported to a local hospital. The victim was pronounced dead on arrival at the hospital. An inspection following the incident revealed that the power cord of the fan was underneath, and had been damaged by the steel base of the fan. The damaged insulation on the conductors allowed the bare conductors to contact the steel base of the fan, energizing the entire frame. When the electrical system for this part of the steel mill had been installed, a continuous ground connection was not established. The fault current present on the frame of the fan had no path to ground until the victim leaned against the fan and simultaneous contacted the handrails for the metal steps which were at ground potential.
