MNM Fatality – 5/22/23

renewcomerLeave a comment

On May 22, 2023, a miner died when the haul truck he was operating overturned, when the edge of the bank at a dump point gave way.  The haul truck landed on the roof of the cab. 

Best Practices

  • Conduct workplace and ground condition examinations before work begins in an area.
  • Dump material from a safe location and push the material over the edge with a bulldozer.
  • Ensure dump locations on unconsolidated material are properly designed, constructed, and maintained.   
  • Construct substantial berms as a visual indicator to prevent overtravel.  Clearly mark dump locations with reflectors and/or markers.
  • Never load material from the toe of a stockpile that is directly below an active dump point.  This may lead to an over steepened and unstable slope.
  • Wear a seatbelt.  Install advanced systems that restrain miners during roll-overs.

Additional Information

This is the 20th fatality reported in 2023, and the fifth classified as “Powered Haulage.”

On February 26, 2023, a contract miner died while operating a bulldozer. The bulldozer traveled over the edge of an access road and rolled feet down an embankment, ejecting the miner from the operator’s cab. The miner was not wearing a seatbelt.

Best Practices

  • Always wear a seatbelt when operating mobile equipment. Monitor work activities routinely to ensure miners wear seatbelts and follow safe work procedures.
  • Examine ground conditions before beginning work and remain alert as conditions change throughout the shift.
  • Train miners on the equipment they operate, including safe work procedures, and to identify and report hazards.
  • Always be aware of your position relative to roadway edges and benches.

Additional Information

This is the ninth fatality reported in 2023, and the second classified as “Machinery”.

  • Keep all exits clear in cabs, including alternate and emergency exits, and make sure the doors and windows open freely before beginning work.

Additional Information

This is the eighth fatality reported in 2023, and the first classified as “Drowning.”

On May 16, 2023, a bulldozer operator died when a spoil pile slid and engulfed the bulldozer he was operating. At the time of the accident, the bulldozer operator was repairing a ramp used to access water pumps in the pit.

Best Practices

  • Establish and follow ground control plans that are consistent with prudent engineering design for the safe control of all highwalls, pits, and spoil banks.  
  • Examine highwalls, spoil banks, and ground that slope into working areas after every rain, freeze, or thaw before work in such areas.
  • Stay clear of potentially unstable areas.  Correct unsafe ground conditions in the affected area.
  • Equip bulldozers with two-way communication systems, high strength glass, and an SCSR for breathable air when working on material that has the potential to slide or engulf mobile equipment.

Additional Information

This is the 19th fatality reported in 2023, and the first classified as “Falling, Rolling, or Sliding Rock or Material of Any Kind.”

MSHA Issues Heat Stress Alert (Again)

renewcomerLeave a comment

It’s as regular as the seasons, HEAT, and as it arrives MSHA alerts us about related health issues. “Mining in hot work areas during summer can cause serious health issues for miners. Everyone needs to recognize the hazards of heat stress and mine operators should provide heat-stress recognition training, monitoring, and personal protective equipment,” says MSHA.

The latest alert contains advice on symptoms and what to do or NOT do to treat them. Most importantly it also says this about Preventing Heat Stress:

  • Provide cool drinking water near miners.
  • Encourage miners to drink a cup of water every 15 to 20 minutes.
  • Avoid drinks with caffeine and large amounts of sugar.
  • Use sunblockers, proper protective clothing and shade.
  • Use administrative controls to rotate miners on hot jobs.
  • Schedule heavy tasks during cooler times of the day.

On April 20, 2023, a contract laborer died while removing the side plate off a shaker screen. The unsupported side plate fell over and struck him.

Best Practices

  • Block machinery components against motion before beginning maintenance or repairs.
  • Ensure blocking material is installed correctly and is of adequate size and strength to support and stabilize the load.
  • Ensure miners position themselves in a safe location and away from potential pinch point areas.
  • Train miners in safe work procedures and hazard recognition. Monitor personnel routinely to ensure they follow safe work procedures.

Additional Information

This is the 17th fatality reported in 2023, and the sixth classified as “Machinery.”

On April 9, 2023, a miner died while mounting off road truck tires on rims.  The miner was in the process of mounting a tire on its rim when another tire’s outer lock ring dislodged, became airborne and struck the victim in the head.

Best Practices

  • Use a tire safety cage (or other tire restraint device) when inflating a truck tire that is not on the truck.  Stand away from the inflating tire and out of the wheel and air blast trajectory during the inflation process.
  • Check tires and rims for damage and defects before performing work.
  • Before repairing tires, completely deflate the tires by removing the valve core and checking the valve stem to make sure it’s clear. 
  • Follow the manufacturer’s procedures and make sure tire and rim components are compatible.
  • Train miners who service tire and rim components. 

Additional Information

This is the 15th fatality reported in 2023, and the fifth classified as “Machinery.”
