MNM Fatality – 1/8/20

A miner fell into a portable load out bin on January 8, 2020, and died at the scene.

Best Practices: 

  1. Check handrails and gates. Ensure handrails and gates are substantially constructed, properly secured, and free of defects.
  2. Install mechanical flow-enhancing devices so workers do not have to enter a bin to start or maintain material flow.
  3. Don’t stand on material stored in bins. Material stored in a bin can bridge over the hopper outlet, creating a hidden void below the material surface.
  4. Lock-out, tag-out. Do not enter a bin until the supply and discharge equipment is locked out.
  5. Wear a safety belt or harness secured with a lanyard to an adequate anchor point before entering a bin. Station a second person near the anchor point to make sure there’s no slack in the fall protection system.
  6. Train all miners to recognize fall hazards and properly use fall protection.
  7. Provide safe access to all work places, and discuss and establish safe work procedures.

Fatality #17 for Metal/Nonmetal Mining 2018

[Note: The Fatality Alert for this first appeared 10/16/19. As noted below the incident didn’t become a fatality until the victim died on 6/27/19.]

On June 15, 2018, a miner fell from a man basket when the weldment securing the basket to the shovel failed. The miner died of his injuries on June 27, 2019.

Best Practices

  • Check for damage. Routinely examine metal structures for signs of weakness (corrosion, fatigue cracks, bent/buckling beams, braces or columns, damaged/loose/missing connectors, broken welds, etc.).
  • Replace cracked equipment fast. Small cracks in equipment can quickly grow into a complete fracture. Take cracked mechanical components out of service immediately.
  • Know the limits. Consult with the manufacturer to determine the service/fatigue life of mechanical systems or parts.

2019 Fatality #19 / Coal #9

On September 5, 2019, a continuous mining machine helper was fatally injured when he was struck by a battery-powered scoop. The victim was in the #3 entry behind a wing curtain that provided ventilation to the #3 right crosscut being mined. The scoop was trammed through the #3 left crosscut and struck the victim as it made a right-hand turn and passed through the wing curtain.

Best Practices: 

  • Install and maintain proximity detection systems on mobile section equipment.
  • Before operating mobile equipment, inform miners of your travel route – especially if changes are being made. Proceed with caution and watch for miners on foot.
  • STOP and SOUND an audible warning device before tramming equipment through ventilation curtains.
  • STAY ALERT around mobile section equipment. Communicate your presence and intended movements to equipment operators.
  • Use transparent curtains for ventilation controls on working sections.
  • Be aware that noise can cause moving equipment to not be heard.

2019 Fatality #20 / Coal #10

On September 17, 2019, an electrician was electrocuted when he contacted an energized conductor. The victim contacted a 995 VAC connector while attempting to troubleshoot the scrubber motor circuit on a continuous mining machine.

Best Practices: 

  • Lock out and tag out the electrical circuit yourself. Never rely on others to do this for you.
  • BEFORE performing electrical work:
    • Open the circuit breaker or load break switch away from the enclosure to de-energize the incoming power cables or conductors.
    • Open the visual disconnect away from the enclosure to confirm that the incoming power cables or conductors have been de-energized.
    • Lock out and tag out the visual disconnect.
    • Ground the de-energized phase conductors.
  • Wear properly rated and well maintained electrical gloves when troubleshooting or testing energized circuits.  After the electrical problem has been found, follow the proper steps before performing electrical work.
  • Use properly rated electrical meters and non-contact voltage testers to ensure electrical circuits have been de-energized.
  • Only use qualified, trained workers. Ensure electrical work is performed by a qualified electrician or someone trained to do electrical work under a qualified electrician’s direct supervision.
  • Identify circuits and circuit breakers. Properly identify all electrical circuits and circuit breakers before troubleshooting or performing electrical work.
