renewcomerLeave a comment

2010 MNM Fatality 22On December 17, 2010, a 35 year- old truck driver with 11 weeks of experience died at a crushed stone operation. The victim was standing on a belt conveyor, working inside a chute, when the belt conveyor started. He was pulled out of the chute and conveyed under two other chutes located on the same belt conveyor. After the belt conveyor was shut down, the victim was found under a third chute.

Best Practices

  • Establish safe work procedures before conducting specific tasks on belt conveyors and ensure that the safe work procedures are followed.
  • Train persons to recognize the hazards of working near belt conveyors.
  • Deenergize and block belt conveyors against motion before working near a chute, drive, head, tail, and take-up pulleys.
  • Lock-out/tag-out all energy sources to belt conveyors before working on them.
  • Sound audible warnings or alarms prior to starting belt conveyors.
  • Maintain communications with all persons performing the task. Before re-starting belt conveyors, ensure that all persons are clear.

  • Provide a clearly marked, safe area for pedestrian access to the facility. Clearly mark areas that are unsafe for pedestrian access and prevent entry into those areas.
  • Ensure that illumination is sufficient at the work site.
  • Before moving mobile equipment, look in the direction of travel, use all mirrors, cameras, backup alarms, and installed proximity detection devices to ensure no one is in the intended path.
  • Sound the horn to warn persons of movement and wait to give them time to get to a safe location.
  • Communicate with mobile equipment operators and ensure they acknowledge your presence.
  • Wear high visibility clothing when working around mobile equipment.

Fatality #13 & #14 for Metal/Nonmetal Mining 2010

renewcomerLeave a comment

On August 12, 2010, a 38 year-old maintenance technician with 3 years of experience and a 47 year-old operations miner with 21 years of experience died at an underground gold mine. They were working from the top of a conveyance in a 16-foot diameter ventilation shaft attempting to locate and free a blockage in a 24-inch-diameter aggregate delivery pipe. While the conveyance was near the 820 foot level, the entire pipe from the shaft collar to the 860 level broke away and fell to the bottom at the 1330 foot level. The pipe struck the conveyance as it fell, causing the hoist drum to break away from its support base. The victims were found at the bottom of the shaft.

Best Practices
  • Routinely examine pipe support structures for indications of excessive corrosion and cracked, missing, or damaged: clamps, brackets, support beams, and connections.
  • Conduct periodic visual and non-destructive examination on couplings and pipes for corrosion, abrasion thinning, cracking, and loose connections.
  • Inspect and test process monitoring systems to ensure safety controls are functioning properly.
  • Perform construction and maintenance in accordance with design drawings and specifications.
  • Minimize exposure to hazards by using equipment such as air cannons and vibrators to prevent or clear blockages.
  • Ensure that miners are in a safe position to avoid falling objects or materials.

On June 20, 2010, a 52 year-old mechanic with 8 years of experience was fatally injured at a surface copper operation. A ½ ton pickup truck had parked in front of a 240 ton haul truck that was also parked. The haul truck pulled forward and struck the pickup truck fatally injuring the driver and seriously injuring another miner.

Best Practices

  • Do not park smaller vehicles in a large truck’s potential path of movement.
  • Before moving mobile equipment, be certain no one is in the intended path, sound the horn to warn possible unseen persons, and wait to give them time to move to a safe location.
  • Ensure all persons are trained to recognize work place hazards, specifically the limited visibility and blind areas inherent to operation of large equipment and the hazard of mobile equipment traveling near them.
  • Establish procedures that require smaller vehicles to maintain a safe distance from large mobile equipment until eye contact is made or approval to move closer is obtained from the mobile equipment operator. Provide training in these procedures.
  • Install cameras and collision avoidance systems on large trucks to protect persons.
  • Regularly monitor work practices and reinforce the importance of them. Take immediate action to correct unsafe conditions or work practices.
