The victim was mounting a haul truck tire on a rim when a rim locking ring dislodged and struck employee, causing fatal injuries.
Final MSHA investigation
On April 9, 2023, Filemon Ortiz, a 63 year-old laborer with approximately ten years of mining experience, died while mounting off-road truck tires on two-piece wheel rims with lock rings (rims). The lock ring from one of the assembled rims dislodged, causing the lock ring to propel into the air and strike Ortiz. The accident occurred because the mine operator did not: 1) correct defects on rims that affected safety to prevent the creation of a hazard to miners, 2) provide task training for mounting tires on rims, and 3) notify MSHA when mining commenced.
Root causes
  1. The mine operator did not correct defects on rims that affected safety to prevent the creation of a hazard to miners.

    Corrective action: The mine operator removed all two-piece wheel rims with lock rings from the mine. All wheel assembly will be conducted by a tire technician off mine property. The mine operator adopted this policy in their Part 46 Training Plan.

  2. The mine operator did not provide task training for mounting tires on rims.

    Corrective action: The mine operator removed all two-piece wheel rims with lock rings from the mine and only one-piece wheel rims will be used at the mine. Additionally, all wheel assembly will be conducted by a tire technician off mine property. The mine operator adopted this policy in their Part 46 Training Plan.

  3. The mine operator did not notify MSHA when mining commenced.

    Corrective action: The mine operator has officially notified MSHA of the commencement ofoperations and MSHA will continue to inspect the mine in accordance with the Mine Act.
