On January 25, 2018, a 38-year old equipment operator with 4 years of mining experience was killed when his articulated haul truck travelled through a berm and into an ice covered pond, submerging the truck’s cab.  Rescuers utilized divers and tow trucks to pull the submerged truck from the pond and recover the victim.

Best Practices

  • Do not operate heavy equipment when fatigued. The effects of fatigue include tiredness, reduced energy, and physical or mental exhaustion. These conditions become progressively worse as fatigue increases.
  • Maintain control and stay alert when operating mobile equipment. Monitor persons routinely to determine safe work procedures are followed.
  • Conduct adequate pre-operational checks and correct any defects affecting safety in a timely manner prior to operating mobile equipment.  Maintain equipment braking and steering systems in good repair and adjustment.
  • Operate mobile equipment at speeds consistent with the conditions of roadways, tracks, grades, clearance, visibility, curves, and traffic.
  • Ensure that berms are adequate for the vehicles present on site, including but not limited to height, material, and built on firm ground.
  • Ensure that all exits from cabs on mobile equipment, including alternate and emergency exits, are maintained and operable.
  • Use seat belts when operating mobile equipment.

Fatality #13 for Metal/Nonmetal Mining 2017

renewcomerLeave a comment

On December 30, 2017, an employee in a pickup truck approached the quarry loadout area to get the Front End Loader (FEL) operator for lunch. The FEL backed into the pickup, pushing it sideways and crushing the driver’s side of the pickup cab, trapping the victim inside the truck. The pickup truck caught fire and efforts by the FEL operator and a nearby contractor to put the fire out using fire extinguishers were not successful.

Best Practices

  • When approaching large mobile equipment, do not proceed until you communicate and verify with the equipment operator your planned movement and location.  Provide radio communication systems between vehicles and large mobile equipment.
  • Ensure all persons are trained to recognize workplace hazards – specifically, the limited visibility and blind areas inherent to operation of large equipment and the hazard of mobile equipment traveling near them.
  • Ensure, by signal or other means, that all persons are clear before moving equipment.
  • Minimize situations where smaller vehicles need to approach large front end loaders.
  • Do not drive or park smaller vehicles in mobile equipment’s potential path of movement.
  • Equip smaller vehicles with flags or strobe lights positioned high enough to be seen from the cabs of haulage trucks.
  • Install and maintain proximity detection or collision avoidance/warning systems and cameras.

On October 31, 2017, a 340-ton haul truck ran over a passenger van carrying nine miners. The driver of the van and the miner in the front seat were fatally injured. Of the remaining seven miners, one suffered a non-life threatening injury.

Best Practices

  • When approaching large mobile equipment, do not proceed until you communicate and verify with the equipment operator your planned movement and location.  Provide radio communication systems between vehicles and large mobile equipment.
  • Ensure, by signal or other means, that all persons are clear before moving equipment.
  • Minimize situations where smaller vehicles need to approach large haul trucks (e.g., arrange for haul truck drivers to have supplies available at the pre-shift meeting place, rather than delivering supplies to the truck).
  • Do not drive or park smaller vehicles in a large truck’s potential path of movement.
  • Equip smaller vehicles with flags or strobe lights positioned high enough to be seen from the cabs of haulage trucks.
  • Install and maintain proximity detection or collision avoidance/warning systems and cameras.
