Fatality #1 for Coal Mining 2010

renewcomerLeave a comment

On January 2, 2010, a 57 year old mechanic with 8 years of mining experience was fatally injured at a surface shop of an underground coal mine. He was repairing a 1-ton truck (mantrip) that was raised and supported by jack stands. The victim was positioned under the truck and the truck’s rear wheels were on the floor. A coworker, who was assisting, entered the truck, depressed the clutch pedal, and started the truck. The truck was in gear when it was started. The coworker’s foot then slipped off the clutch pedal of the standard transmission, causing the truck to lurch forward, fall off the jack stands, and strike the victim.

Best Practices

  • Block vehicles against motion in all potential directions of movement prior to any work.
  • Keep standard transmission vehicles in neutral with the park brake engaged when work is performed on the vehicles.
  • The vibration of a running motor may cause blocked or jacked equipment to move or fall off of its blocks or jacks. Position yourself out of the path of travel in the event a failure occurs.
  • Observe blocking and jack stands during loading and ensure they remain solid without any tilting or sliding. The slots at the head of the jack should properly couple with the jack points underneath the vehicle.
  • Metal to metal contact may slide much easier than wood or other materials against metal. This is a good reason to ensure everything remains level and evenly loaded. Also, remove any grease or lubricants from the area that will contact the blocking/jack stand.
  • Jacks and blocks should be positioned on level ground and ensure they are all raised to equal heights.
  • If available, use a pit to perform maintenance work on the underside of mobile equipment.

On September 27, 2009, a 28 year-old truck driver with 2 years of experience was fatally injured at a copper operation. He was operating a 240-ton haul truck that left the haul road and climbed a berm, causing it to overturn and land on the haul road. The victim, who was not wearing a seat belt, fell from the cab of the truck.

Best Practices

  • Always wear a seat belt when operating a haul truck or mobile equipment.
  • Monitor employees regularly to ensure seat belts are worn when operating mobile equipment.
  • Maintain control and stay alert when operating mobile equipment.
  • Conduct pre-operational checks to identify and correct any defects that may affect the safe operation of self-propelled mobile equipment.

On September 15, 2009, a 59 year-old delivery driver with 14 years of experience was fatally injured at a sand and gravel operation. She parked off mine property and walked on site to deliver a package. The victim walked behind a front-end loader that backed over her.

Best Practices
  • Establish a visitor control policy that includes signs directing visitors to a safe location.
  • Train delivery persons to recognize work place hazards they could be exposed to while at the mine.
  • Always make sure equipment operators see you before entering any area where mobile equipment is operated. If possible, make eye contact with the equipment operator. When moving to a different area, inform
    the equipment operator before leaving the area.
  • Before moving mobile equipment, look in the direction of travel, use all mirrors, cameras, and installed proximity detection devices to ensure no one is in the intended path.
  • Ensure that all persons are clear before moving equipment. Sound your horn to warn unseen persons that you are about to move and wait a few moments to give them time to get to a safe location.
  • Ensure that backup alarms on mobile equipment are maintained and operational.

On June 11, 2009, a 57-year old mechanic with 31 years of experience was fatally injured at an underground lead/zinc mine while checking for a hydraulic leak on a loader. The victim leaned into the ejector plate relief port in the back of the loader bucket. The ejector plate of the bucket was retracted, crushing him against the back of the bucket.

Best Practices
  • Train persons to recognize work place hazards.
  • Establish safe work procedures before a task is performed.
  • Securely block equipment and components against hazardous motion at all times while performing maintenance work.
  • If equipment and components are to be moved, always verify persons are aware and in a safe location prior to movement.
  • Consult and follow the manufacturer's recommended safe work procedures for the maintenance task.

  • Sound the horn to warn persons of movement and wait to give them time to get to a safe location.
  • Operate mobile equipment at reduced speeds in work areas.
  • Do not operate mobile equipment in reverse for extended distances when it is possible to travel forward.
  • Be aware of the location of mobile equipment in your work area before exiting your equipment.
  • Communicate with mobile equipment operators and ensure they acknowledge your presence.
  • Wear high visibility clothing when working around mobile equipment.
