Texto original en inglés de la MSHA

On March 28, 2026, at 9:00 a.m., Carlos Lopez, a 19-year-old millwright/iron worker, with over 1 year of mining experience, died when he detached from a fall protection tie-off point to navigate to another area of the roof and fell about 37 feet and 6 inches through an unsecured roof panel. The accident occurred because: 1) the contractor did not ensure contract employees remained tied off while exposed to a fall hazard; and 2) the mine operator and contractor did not conduct a thorough workplace examination to identify hazards on the damaged roof.

1. The contractor did not ensure contract employees remained tied off while exposed to a fall hazard.

   Acción correctiva: The mine operator and contractor implemented a policy requiring continuous use of fall protection when working at heights and will conduct routine monitoring to ensure compliance.

2. The mine operator and contractor did not conduct a thorough workplace examination to identify hazards on the damaged roof.

   Acción correctiva: The mine operator and contractor revised their workplace examination procedures to ensure all work areas, including elevated and interior hazard exposures, are evaluated and documented.
