On January 9, 2010, a 20 year-old contractor laborer with 21 weeks of experience was fatally injured at a copper operation. Two track excavators were being used to place a 400-foot long section of 24-inch diameter plastic pipe into a pond. To facilitate the installation process, the pipe was placed on top of an adjacent section of pipe that was previously placed on the plastic lining of the pond. During installation, the pipe being installed misaligned and the victim and two coworkers attempted to remove the end of this pipe from the top of the existing pipe. At that time, the end of the pipe shifted, hit a coworker, and then struck the victim. The victim fell to the ground and the pipe landed on him. The coworker was not injured.

Best Practices

  • Task train all persons prior to performing any work.
  • Always stay clear of suspended loads.
  • Use taglines of sufficient length to adequately protect persons from potential hazards.

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 July 2, 2009, a 52-year old mine owner with 34 years of experience was fatally injured at a surface dimension stone operation. He was working alone and was operating a walk behind masonry saw on a ledge. Apparently he was positioned between the saw and the edge when he tripped and fell.

Best Practices
  • Identify all hazards and use appropriate controls to protect persons.
  • Ensure that operators are in a safe position and have control of their equipment at all times.
  • Keep workplaces free of tripping hazards.
  • Use barricades or railings at edges of drop-offs where persons are in danger of falling.
  • Equip walk behind masonry saws with devices to stop the engine if the operator can not maintain control of the equipment.
  • Design bench top stone cutting patterns so the saw operator is not positioned between the saw and the drop off edge.
