## Narrative

A power outage at the substation caused a power failure to the Nordberg Hoist and entire site.  When the back-up generator/emergency power was started the push button for the circuit breaker failed to close the circuit breaker so no power was being supplied to the workdeck winches used to evacuate men. Ventilation was interupted for more than 15 minutes.
