Texto original en inglés de la MSHA

On October 1, 2022, at 8:13 a.m., Darren Miller, a 35 year-old mechanic with over 47 weeks of mining experience, died when he was struck by the overhaul hook ball on a crane. The crane was being used to install an engine and transmission in a haul truck when the overhaul hook ball detached and fell. The accident occurred because the mine operator did not: 1) ensure that the mechanic stayed clear of suspended loads while replacing the engine in the haul truck, and 2) remove the crane from service to prevent operation in an unsafe manner.

1. The mine operator did not ensure that the mechanic stayed clear of suspended loads while replacing the engine in the haul truck.

   Acción correctiva: The mine operator developed and implemented a new written procedure for working near suspended loads. All miners were trained in this new procedure.

   Acción correctiva: The crane involved in the accident was permanently removed from service. The mine operator developed and implemented a new written procedure for out of service criteria of mobile equipment. All miners were trained in this new procedure.
