Texto original en inglés de la MSHA

On January 4, 2023, at 2:45 p.m., John Ogle, a 28 year-old plant operator with approximately two years of mining experience, was fatally injured when the swing jaw of the primary jaw crusher (crusher) moved as he was performing maintenance, pinning him between the back side of the swing jaw and toggle block frame. The accident occurred because the mine operator did not: 1) block moveable parts of the crusher against hazardous motion, 2) provide adequate task training for maintenance work on the crusher, and 3) conduct an adequate workplace examination of the work area.

1. The accident occurred because the mine operator did not block moveable parts of the crusher against hazardous motion.

   Acción correctiva: The mine operator revised and implemented a written procedure for blocking machinery against hazardous motion to comprehensively address stored energy. The mine operator trained all miners on the procedure.

2. The mine operator did not provide adequate new task training for maintenance work on the crusher.

   Acción correctiva: The mine operator revised their training plan to include comprehensive safety procedures for maintenance work. The plan includes task training, proper crusher examination, correction of any hazards prior to starting work, and blocking of all energy sources. The mine operator trained all miners on the revised procedures.

3. The mine operator did not conduct an adequate workplace examination.

   Acción correctiva: The mine operator developed and implemented a new written procedure for workplace examination to ensure that miners identify, correct, and report hazardous conditions. The mine operator trained all miners on the new procedure.
