Safety Alert

Underground Mobile Equipment

Four accidents involving underground mobile equipment occurred from 9/26/2023 to 10/16/2023. One fatality and three serious injuries resulted when miners were pinned between underground mobile equipment and the coal rib.

Best Practices

Establish operating procedures to ensure that:

  • Mobile equipment is maintained in safe operating condition. Remove unsafe equipment from service.
  • Avoid pinch points and “Red Zone” areas.
  • Miners operate equipment from a safe location. Wear reflective clothing.
  • Miners communicate their presence and intended movements when working around mobile equipment and wait for acknowledgment before moving.
  • Miners sound audible warnings, distinguishable from surrounding noise, before moving equipment and when approaching and before traveling through check curtains.
  • Miners are trained on the safety aspects, safeguards, and safe operating procedures of mobile equipment before use.
