Note: This alert was posted as a Safety Alert for Tire Explosion on 7/19/24 and didn’t come up on my radar as a specific Fatal Alert. Sorry for the delay in posting to this site. – Randy

On June 14, 2024, one firefighter died, and another was injured when a front end loader tire exploded while firefighters fought the equipment fire.

Best Practices

In the event of a possible or actual fire (e.g., odor, heat, smoke, flames):

  • Stop the machine, lower all attachments, set the parking brake, and turn the equipment off.
  • Actuate the machine-mounted fire suppression system, if available.
  • Safely exit the machine and retreat to a safe location, preferably 1,000 feet away.
  • Warn all others in the vicinity of the fire, notify management, and contact appropriate emergency personnel.
  • Do not attempt to extinguish a tire fire with a hand-held extinguisher.
  • Wait for emergency responders to arrive. Stay clear of the fire.
  • From a distance, emergency personnel can use a fire or water truck to cool down the equipment. (See SAE J2828NOV2016 – Off-Road Tire Handling Guidelines.)

  • Use a spotter when moving mobile equipment in congested areas and around structures.
  • Monitor miners routinely to ensure miners follow safe work procedures while operating personnel lifts. 
  • Ensure miners are aware of their location in relation to nearby structures.
  • Conduct workplace examinations to identify and eliminate hazards before beginning work in an area.
  • Train miners in the safe performance of their tasks in accordance with the manufacturer’s manual.

Additional Information

This is the sixth fatality reported in 2024, and the fourth classified as “Powered Haulage.”

On May 8, 2024, a miner was electrocuted while unloading a roll of belt from a trailer.  The miner was performing rigging duties when the crane boom contacted an overhead high-voltage powerline.

Best Practices

  • Ensure that booms or masts of equipment are not operated within 10 feet of any energized overhead powerline.
  • Designate one person on the ground, located in a safe location, to give signals to the crane operator and watch placement and proximity of the boom.
  • Use non-conducting tag lines to steady loads when operating cranes where overhead power lines are present.
  • Post warning signs at all approaches to overhead powerlines; install barricades where necessary.

Additional Information

This is the fifth fatality reported in 2024, and the first classified as “Electrical.”

This fatality never had an alert posted individually by MSHA but was mentioned in this Electrical Saety Alert. The following text is from the Final Report.

On February 6, 2023, at approximately 3:45 p.m., Javier Regalado-Cano (Regalado), a 61 year-old haul truck driver with over a year of mining experience, was fatally injured when he received an electrical shock. While Regalado was operating a haul truck, he raised the bed of the haul truck into the energized 13,800-volt phase-to-phase power lines (power lines). Regalado exited the haul truck and extinguished a fire on the haul truck’s left rear dual tires. Regalado received an electrical shock when he contacted the energized haul truck while reentering it. 

The accident occurred because the mine operator did not: 1) install warning devices for the power lines, and 2) de-energize or take other precautionary measures when mobile equipment was operating near energized power lines.

On April 25, 2022, MSHA was informed of a miner’s death. MSHA’s initial findings indicated medical-related issues as the cause of death. Because of the circumstances surrounding the accident, MSHA referred the accident to the Agency’s Chargeability Review Committee (Committee). On March 28, 2024, the Committee determined that this death should be charged to the mining industry.

On April 25, 2022, co-workers found a maintenance worker lying face down in a pool of water.  The maintenance worker was using a water hose to wash out fine material that had gathered under a tail pulley.

Best Practices

  • Maintain workplaces in a clean and dry condition when possible. 
  • Where wet processes are used, maintain drainage platforms, mats, or other dry standing places.
  • Ensure that miners have communication systems available when assigned to work alone.
  • Routinely check in on miners working alone.
  • Conduct workplace examinations before work begins in an area.

Additional Information

This is the 30th fatality reported in 2022, and the third classified as “Drowning.”

MNM Fatality – 1/2/24

renewcomerLeave a comment

On January 2, 2024, the driver of an over the road tractor-trailer haul truck died when the trailer tipped over onto the cab of the tractor. The driver was dumping part of the load of gravel from the trailer. Between 2018 and 2024, mine operators reported 14 injury accidents where over the road trucks tipped or rolled over while dumping. During the same period, miners were also injured when 28 off-road mine haul trucks tipped or rolled over. 

Best Practices

  • Dump only on level surfaces, free of spillage. Make sure elevated dump sites are substantial and equipped with adequate dump point restraints.
  •  Keep your truck and trailer in a straight line when backing up and never move faster than walking speed.
  • Avoid dumping in high or gusty wind conditions.
  • Stay in the cab with your seatbelt on during the dumping process. Never attempt to exit or jump from an overturning truck.
  • After dumping, remove any compacted material before reloading the truck.
  • Evenly distribute the load and use antifreeze in cold weather to prevent material from freezing and sticking in the truck bed.
  • Never overload trucks or trailers.
