renewcomerLeave a comment

On August 14, 2010, a 23 year-old dredge operator with 4 years of experience died at a sand and gravel dredge operation. The victim and another miner were pulling a small boat from a dredge pond onto a boat trailer attached to a pickup truck. When the boat slipped back into the water, the victim attempted to retrieve it and drowned.

Best Practices
  • Wear a life jacket where there is a danger from falling into water.
  • Review procedures to ensure all possible hazards have been identified and appropriate controls are in place to protect miners before beginning work.
  • Develop procedures for loading and unloading boats in dredge operations and train all persons.
  • Inspect equipment, including the winch and cable, prior to use and maintain in a safe condition.
  • Attach the trailer winch rope securely to the boat prior to removing from the water.
  • Ensure that persons working around water receive training for swimming.

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 May 1, 2009, a 59-year old dredge operator with 3 years of experience was fatally injured at a dredging operation. The victim was trying to manually guide the wire cable onto one of two positioning winches on the dredge when he became entangled in it.

Best Practices

  • Conduct a complete pre-operational inspection of equipment that includes checking winches and cables.
  • Install new winch cables to reel in the same direction as the old cable.
  • Inspect winches to confirm proper reeling of the cable.
  • Assign two persons to perform maintenance tasks on dredges.
  • Block equipment against hazardous motion before performing maintenance tasks.
  • Label valve bank levers to indicate direction of movement.
  • Do not wear loose clothing when working near moving machine parts.

On April 21, 2009, a 51-year old contract laborer with 3 years of experience was fatally injured at a sand and gravel dredging operation. The victim was inside an excavation ditch while an excavator was maneuvering a concrete box into place. The chain used to attach the four leg sling from the box to the excavator broke. The box fell into the hole and struck the victim crushing him.

Best Practices

  • Identify hazards associated with the task to be performed, review those hazards with all personnel involved, and implement measures to ensure persons are properly protected.
  • Communicate lift plans to all persons working in the lift zone to ensure that no one is under a suspended load.
  • Stay clear of a suspended load.
  • Attach taglines to loads that may require steadying or guidance while suspended.
  • Use sling or chain assemblies (rigging) specifically intended for lifting and adequately rated for the loads being lifted.
  • Carefully inspect all rigging prior to each use.

On February 19, 2009, a 61 year-old laborer with 12 years of experience was injured at a sand and gravel operation when he was struck by a crane’s falling boom. The crane was lifting a crusher and the victim was acting as a signalman when the accident occurred. He was hospitalized and died on April 12, 2009, as a result of his injuries.

Best Practices

  • Prior to attempting a lift, know the weight of the load (including the load block and rigging) and make sure it is less than the crane’s lifting capacity for the required reach. Refer to applicable load charts.
  • Perform a thorough pre-operational inspection of the crane and rigging components.
  • Stay clear of a crane’s overhead boom and do not work beneath a suspended load.
  • Always be certain that the object being lifted is completely detached from its supporting structure prior to attempting a lift.
  • Insure that the crane turntable is level prior to lifting.
  • Make sure the load is aligned directly beneath the centerline of the boom to prevent side loading.
  • Confirm that the load will not exceed the allowable capacity of the rigging.
  • Follow the crane manufacturer’s recommendations when making structural repairs and use certified welders.

On April 7, 2009, a 36 – year old supervisor with 15 years of experience was fatally injured at a sand and gravel dredging operation. The victim was attempting to connect the 4160 volt cable for the dredge to load side terminals in the electrical panel when he came into contact with energized 4160 volt line side terminals.

Best Practices

Before YOU perform electrical work:

  • Be trained and knowledgeable in the task.
  • Be trained on all the electrical test and safety equipment necessary to safely test and ground the circuit being worked on.
  • Use properly rated Personal Protective Equipment including Arc Flash Protection such as a hood, gloves, shirt, and pants.
  • Positively identify the circuit on which work is to be conducted.
  • De-energize power and ensure that the circuit is visibly open.
  • Place YOUR lock and tag on the disconnecting device.
  • Verify the circuit is de-energized by testing for voltage using properly rated test equipment.
  • Ensure all electrical components in the cabinet are de-energized.
  • Ground ALL phase conductors to the equipment grounding medium with grounding equipment that is properly rated.

On January 6, 2009, a 41 year-old laborer with 3 years of experience was injured at a sand and gravel operation. The victim was operating a skid steer loader underneath a belt conveyor that was being dismantled. Two coworkers were in an elevated manlift removing a 12-foot piece of 4-inch metal tubing from the leg supports of the belt conveyor frame. The tubing fell into the front of the skid steer loader as it approached the work area, striking the victim. He was hospitalized and died on January 9, 2009. The red line shows the original location of the tubing.

Best Practices

  • Establish and review procedures to ensure all possible hazards have been identified and appropriate controls are in place to protect persons before beginning work. Discuss procedures with all persons present in the work area.
  • Establish policies to ensure that barricades or warning signs are installed to prohibit access and protect persons from falling object hazards.
  • Remove all persons from beneath the area where overhead work is being performed.
