A 33-year old electrician with six years mining experience was fatally injured while repairing a damaged 995 volt trailing cable. During a mine-wide power outage, the victim began repairing a damaged continuous mining machine trailing cable. While preparing to splice the third and final power phase, underground electrical power was restored and the electrical circuit breaker was engaged in the closed position causing a fatal electrical shock.
Personally lock-out and tag-out electrical circuits before you perform electrical work on a cable or component. Do not rely on others to deenergize or disconnect a circuit for you. Never assume a circuit breaker will not be reset - even if there is no apparent reason for resetting the breaker. Never disturb or ignore an electrical tag or lock. Communicate to determine that it is appropriate to reset a breaker
