On March 3, 2026, a contractor died while working in an excavated area when the adjacent concrete block retaining wall collapsed.

Best Practices

  • Conduct inspections before working near retaining walls or earth-retaining structures. Look for signs of movement, cracking, bulging, loose blocks, seepage, or soil erosion.
  • Stay clear of potentially unstable areas.
  • Maintain a safe distance. Keep personnel, equipment, and materials back from the top and base of retaining walls to prevent surcharge loading or vibration that could cause sudden wall failure.
  • Never work directly below or adjacent to unsupported or unprotected excavations or unstable retaining walls. Use barricades, controlled access, or engineered protection to prevent exposure to falling blocks or wall collapse. 
  • Train miners in safe work procedures and hazard recognition.

Additional Information

This is the third fatality reported in 2026, and the first classified as “Falling, Rolling, or Sliding Rock or Material of Any Kind.”

On January 8, 2026, an over-the-road truck driver died after he became pinned between the dump bed and the frame of a truck.

Best Practices

  • Establish and discuss safe work procedures before beginning work. Identify and control all hazards associated with the work and use methods to properly protect persons. 
  • Before working on equipment, block all raised components against motion and ensure persons are positioned in a safe location and away from the “red zone” areas.
  • Never work under a load that is unsupported or inadequately supported. Observe and follow all warning labels and signs on equipment.

Additional Information

This is the second fatality reported in 2026, and the first classified as “Powered Haulage.”

On January 6, 2026, a contractor was fatally struck by the motor and gearbox assembly while removing a baghouse slide gate. 

Best Practices

  • Block machinery or equipment against hazardous motion before beginning maintenance or repairs. Verify miners are in a safe location and away from potential “red zone” areas.
  • Secure assemblies to prevent unexpected movement and use proper tools.
  • Identify and control all stored energy sources, including gravity.
  • Train miners in safe work procedures and hazard recognition.

Additional Information

This is the first fatality reported in 2026, and the first classified as “Machinery.”

On December 22, 2025, a contractor died after receiving burns from a pressurized hydraulic line that ruptured and caught fire.  The contractor was cutting shims from a cone crusher with a torch.

Best Practices

  • Never apply heat to or near pressurized hydraulic lines.
  • Never apply heat to components when flammable, combustible, or explosive materials are present.
  • Protect and/or relocate hydraulic lines to prevent physical damage.
  • Examine all components and surrounding areas before applying heat, cutting or welding. Conduct daily inspections of hydraulic equipment, hoses, and connections for leaks, wear, or damage.
  • Always use proper protective equipment for the task.

Additional Information

This is the 33rd fatality reported in 2025, and the first classified as “Exploding Vessels under Pressure.”

On December 10, 2025, two contractors died when the dragline they were operating slid into a water-filled pit.

Best Practices

  • Establish mining methods based on geological conditions such as soil stability subsurface cavities.
  • Evaluate all pit, highwall, slope, and bank conditions at least daily or more often, if necessary, to protect the health and safety of the miners. Be especially vigilant after each rain, freeze, or thaw.
  • Conduct effective workplace examinations in areas where miners are working and traveling. Identify and correct all hazards.
  • Train miners on equipment risks and to recognize potential hazards that can decrease bank and slope stability.

Additional Information

These are the 30th and 31st fatalities reported in 2025, and the fifth and sixth classified as “Machinery.”

On November 22, 2025, a plant operator died after he was struck and engulfed by falling material at a salt silo discharge outlet. He was attempting to clear a blockage with his head and arm inside the silo access door.

Best Practices

  • Equip bins and hoppers with mechanical devices such as vibrating shakers or air cannons to loosen blockages or provide other effective means so miners are not exposed to caving or sliding materials.
  • Ensure miners are positioned in a safe location and away from potential hazards.
  • Make sure miners working under hazardous conditions can be seen, heard, and able to communicate with others.
  • Examine working places to identify the potential for falling or sliding materials prior to allowing access to areas in or around bins and hoppers.
  • Before blocked bins and hoppers are cleared, train miners to recognize and safely remove all potential hazards.

Additional Information

This is the 29th fatality reported in 2025, and the first classified as “Handling Material.”
