Deaths Due to Improper Use of Extension and Flexible Cords
Flexible Cord Not 3-Wire, Hard Service Variety
A worker received a fatal shock when he was cutting drywall with a metal casing router. The router's
3-wire power cord was spliced to a 2-wire cord and plug set which was not rated for hard service. A fault
occurred, and with no grounding and no GFCI protection, the worker was electrocuted.
No Strain Relief
A worker was operating a ¾" electric chisel when an electrical fault occurred in the casing of the tool,
causing him to be fatally electrocuted. An OSHA inspection revealed that the tool's original power cord had been
replaced with a flat cord, which was not designated for hard service, and that strain relief was not provided at the
point where the cord entered the tool. Additionally, the ground prong was missing and there was no GFCI
protection.
