c05.jpgOn May 28, 2015, a 45-year-old surface foreman with 27 years of experience was killed when he was crushed between the frames of a road grader and a tractor that was transporting a base power module for a highwall miner.  The foreman was in the process of connecting a chain between the two machines when the road grader rolled back and crushed him.

Best Practices

  • Never position yourself between equipment that is not blocked and secured from movement.
  • Turn the engine off, place the transmission in gear, set the park brake, and always ensure equipment is securely blocked against motion, before performing repair or maintenance work, which includes connecting tow bars.
  • Use a tow bar with adequate length and proper rating when towing heavy equipment.  A chain should never be used to tow mobile equipment.
  • If mobile equipment must be towed, the equipment should be on level firm ground and secured from movement prior to connecting the equipment.
  • Ensure miners are adequately trained on proper towing procedures.
  • Ensure mobile equipment operators are aware of your location at all times.
  • Maintain communications with mobile equipment operators while working in close proximity to equipment.  Utilize radios to communicate when visual contact cannot be maintained.
  • Maintain equipment braking systems in good repair and adjustment.  Do not depend on hydraulic systems to hold mobile equipment stationary.
  • Conduct pre-operational examinations to identify and repair defects that may affect the safe operation of equipment before it is placed into service.

c01.jpgOn Wednesday, January 28, 2015, a 43-year-old continuous mining machine operator with 10 years of mining experience was killed when he was pinned between the conveyor boom of a remote controlled continuous mining machine and a coal rib.  The victim was operating the continuous mining machine from a remote position in the entry and was preparing for the next mining cycle when the accident occurred.

Best Practices

  • Install and maintain proximity detection systems to protect personnel and eliminate accidents of this type. See the proximity detection information page on the MSHA website (Proximity Detection Single Source).
  • Avoid “RED ZONE” areas when operating or working near a continuous mining machine, especially when moving a remote controlled continuous mining machine.  Frequently review, retrain, and discuss avoiding “RED ZONE” areas (http://www.msha.gov/Alerts/20040407REDZONE2.pdf).
  • Ensure all miners, including the continuous mining machine operator, are outside the machine’s turning radius before starting or moving equipment.
  • Stay behind moving mobile equipment when traveling in the same entry, and maintain a safe distance from any moving equipment.
  • Use low tram speed when moving a continuous mining machine where the left and right traction drives are operated independently.  The continuous mining machine pivots quickly when the tracks tram over raised areas of the mine floor.
  • Never turn your back to a self-propelled machine or get into an area where it can swing into you.
  • Develop and follow effective policies and procedures for starting and tramming self-propelled equipment.  Train all miners regarding these policies and procedures.
  • Ensure that the continuous mining machine operator has full visibility of the area while tramming equipment.
  • Assign another miner to assist the continuous mining machine operator when the machine is being moved or repositioned.

m04On January 26, 2015, a 57-year old heavy equipment operator with 36 years of experience was seriously injured at a phosphate mine.  He was operating an excavator near a water filled ditch when the excavator tipped forward and went in the water, submerging the cab.  The victim was removed from the cab and transported to a hospital where he died later that day.

Best Practices

  • Task train all persons to recognize all potential hazardous conditions and safe job procedures to identify and eliminate all hazards before beginning work, specifically the limited visibility of large equipment.
  • Discuss safe work procedures before beginning work.  Identify and control all hazards associated with the work to be performed and the methods to properly protect miners.
  • Provide traffic patterns and roads that minimize the danger of machines traveling near bodies of water.
  • Conduct examinations of travelways to evaluate hazards.
  • Install barriers, markers, or other warning devices to aid equipment operators where travelways are not recognizable or hazards are not apparent.  Limit travel of mobile equipment and inform mobile equipment operators of hazards.
  • Do not travel into areas where ground conditions can’t be verified.  If necessary, use the bucket of the machine to probe the travel/work area to check the ground conditions.

c14aOn Monday, September 15, 2014, a 53-year old bulldozer operator, with 28 years of experience, sustained fatal injuries when the bulldozer he was operating went over the edge of an approximately 50-foot highwall. The victim was preparing a bench for drilling when the accident occurred.
Best Practices

  • Be familiar with the work environment. Before beginning work, walk around and check the area. Plan the safest way to move the material and maneuver the equipment.
  • Train all employees adequately on the equipment they operate, safe work   procedures, hazard recognition, and hazard avoidance.
  • Be attentive to changes in ground conditions and visibility. Watch for surface cracks and loose material.
  • Keep the dozer blade between you and the edge when operating close to drop offs.  Dump loads short of the highwall edge and push one load into another to maintain a safe distance from the edge.
  • Maintain all equipment window glass clean and in good repair.
  • Maintain a safe distance from the edge of the highwall.  Use a spotter or other technology to assist equipment operators when working near highwalls.
  • Perform additional checks during the work shift to ensure ground conditions have not changed when the edge of a slope cannot be seen from the operator’s position
  • Ensure that personnel operating mobile equipment always wear a seat belt.
  • Monitor work activities to assure safe work procedures are followed.
