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.

Fatality #2 for Metal/Nonmetal Mining 2009

On January 17, 2009, a 48 year-old mill operator with 22 weeks of experience was fatally injured at a crushed stone milling operation. The victim was loading material into a hopper with a front-end loader. He entered the hopper to dislodge frozen bridged material that would not feed onto the belt conveyor below. Coworkers found the victim engulfed in the hopper.

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.
  • Train miners in safe work procedures and hazard recognition, specifically when clearing blocked hoppers.
  • Lock out discharge operating controls.
  • Ensure a safety harness properly secured to a lanyard is worn and a second person is positioned outside to adjust the lanyard.
  • Management should routinely monitor these activities to ensure miners are protected from possible hazards.
  • Provide vibrating shakers to maintain material flow or mechanical means of safely removing material if hoppers experience recurring flow problems.

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.
