On October 19, 2021, at approximately 1:50 p.m., David Steen, a 58 year-old mechanic with 17 years of mining experience, was fatally injured when the haul truck dump body fell and pinned him against the truck frame. The accident occurred because the mine operator did not: 1) assure that the equipment was blocked against motion before the miner performed maintenance, and 2) train the miner on how to perform the task assigned to him.

1. The mine operator did not assure that the equipment was blocked against motion before the miner performed maintenance.

   Acción correctiva: The mine operator developed a new written procedure for blocking against motion. The procedure requires a supervisor to confirm the blocking arm is properly placed in the socket when the dump body must be raised to perform work on or around an articulated haul truck. The mine operator trained all miners on the new procedure.

2. The mine operator did not train the miner to perform the task assigned to him.

   Acción correctiva: The mine operator created a Job Safety Analysis (JSA), as required by the approved training plan. The mine operator trained all miners on their assigned tasks and how to use the JSA.
