On Feb. 22, 2021, a 26-year-old underground chute puller was fatally injured as a passenger of a rail-mounted locomotive when he was crushed between the deck of the locomotive and an overhead chute at a lead-zinc ore underground mine with 114 employees in Strawberry Plains, TN*.

Best Practices: 

  • Install controls such as rail stops at loading points, crossings, etc., where track equipment must stop. 
  • Install reflective signs or warning lights well in advance of low clearance areas to alert miners of the upcoming hazard.
  • Develop safe working procedures to avoid low clearance and pinch point areas.  Monitor workers to ensure these procedures are followed.
  • Always look in the direction the equipment is moving in, and keep all body parts within the operator’s compartment while a vehicle is moving.
  • Conduct proper travelway examinations to identify and mitigate the hazards presented by low clearances. 
  • Train all workers to recognize potential hazards and understand safe job procedures and tasks to eliminate hazards before beginning work.
