Texto original en inglés de la MSHA

1. Contractor management procedures failed to ensure that the electrical circuit breaker was de-energized prior to performing work on it.

   Acción correctiva: Mine management conducted training classes for all employees at the mine regarding lock-out and tag-out policies and procedures. All electrical contractors will be trained in the future regarding proper lock-out and tag-out and "bottom feed" circuit breakers. The main electrical circuit breaker was replaced with a "top feed" circuit breaker. Management verified that Snyder did not have any additional "bottom feed" circuit breakers at Snyder.
