Texto original en inglés de la MSHA

On August 18, 2020, at 6:15 a.m., Diego Resendiz, a 21-year-old Laborer/Equipment Operator with over one year of mining experience, entered the cone crusher and falling material entrapped him beneath the feed hopper. Resendiz was rescued and died the next day. The accident occurred because Hi-Grade Materials did not: 1) establish safe procedures to clear blockages in feed hoppers or bins, 2) provide access to areas from which blockages could be cleared safely, 3) provide mechanical devices or other effective means to prevent and/or safely clear blockages, and 4) adequately train miners in entry to bins, hoppers, tanks or similar areas.

1. Management did not adequately train miners in health and safety aspects of assigned tasks.

   Acción correctiva: Hi-Grade Materials Co. developed a written policy based upon a Job Task Analysis to determine and identify the hazards of specific tasks, PPE requirements, safe procedures and access that includes hands on training in the field. The training plan was amended to include this policy.

2. Management did not have adequate controls in place to prevent or safely access/remove material blockages in the hopper system.

   Acción correctiva: Hi-Grade Materials Co. reviewed and analyzed the material flow of the entire crusher system to allow material to flow smoothly through the plant and modified access to allow safe removal of blockages if needed. The operator also has on site tools and PPE to address such hazards. The mine operator has trained miner on the modified process, tools, and PPE.

3. Management did not conduct and record work place examinations prior to any work commencing.

   Acción correctiva: Hi-Grade Materials Co. has conducted training with all employees to ensure understanding the importance of conducting, hazard recognition, and corrective action required to meet compliance with the standard. The training plan was amended to include workplace examinations. The company has instituted a policy that includes management audits of workplace examinations.
