MSHA Fatality Alert - August 23, 2022 Fatality


September 15, 2022 - On August 23, 2022, a contract mechanic received fatal injuries while performing maintenance on the bucket (dipper) of an electric rope shovel.  A plastic block, used to prop open the dipper door, dislodged causing the dipper door to close and pin the victim against the back edge of the dipper.

Best Practices:

  • Make sure miners are positioned in a safe location and away from potential pinch point areas.
  • Make sure miners securely block equipment against motion before beginning maintenance or repairs.
  • Assure blocking material is substantial and installed correctly to support and stabilize the load.
  • Make sure miners conduct repairs according to manufacturer’s recommendations.
