Texto original en inglés de la MSHA

On November 22, 2025, between 2:30 p.m. and 3:30 p.m., Martin Delgado, a 60-year-old plant operator with over 27 years of mining experience, died after he was engulfed by material at the Silo No. 6 access door. Delgado was in the process of cleaning and clearing a blockage in the silo. The accident occurred because the mine operator did not equip Silo No. 6 with effective means of handling materials to prevent the plant operator from being required to enter or work where he was exposed to entrapment by caving or sliding materials.

1. The mine operator did not equip Silo No. 6 with effective means of handling material to prevent the plant operator from being required to enter or work where he was exposed to entrapment by caving or sliding materials.

   Acción correctiva: The mine operator sealed all silo access doors by welding and cut vents in the tops of the silos to wash out remaining salt with water hoses. The mine operator developed and implemented a written procedure to use the vents when cleaning and clearing blockages from the silos.
