Workers can be at risk of injury or even death if hazards exist involving motor vehicles such as locomotives, haulage trucks, loaders and load haul dump (LHD’s) at underground and surface mines.

These hazards can be prevented by putting measures and procedures in place to protect workers. Such measures can include proper reflective clothing, effective illumination, monitoring work conditions, education and training, and having a traffic management program in place.

Employers are responsible for protecting workers from hazards involving moving material in mines.

Hazards can include:

  • workers contacted by moving equipment
  • equipment contacting other equipment
  • workers operating equipment around open brow, or inside open stopes
  • equipment going over the edge of a pit/quarry or open hole
  • remote stands that are not properly secured
  • operating vehicles that are unsafe

From 2000 to 2015, 14 workers died in Ontario mines as a result of collisions and other incidents involving motor vehicles and mobile equipment.
