MNM Fatal 2005-24

Overview
  • The victim was fatally injured when the 50-ton
    haul truck he was operating overturned. He was
    preparing to dump a load of rock over the edge of
    the 21-foot high truck dump site when a portion
    of the dump site failed. The collapse caused the
    truck to overturn and land on its roof.

Causal Factors
  • Policies, standards, and controls were inadequate
    and failed to ensure that berms or similar
    impeding devices were maintained at the dump
    site.
  • Procedures were not in place to ensure that the
    dump site was inspected for hazards before a haul
    truck dumped the first load. Material had been
    loaded from the stockpile directly below the dump
    locations which steepened the slope angle and
    reduced the stability.
  • Procedures were not in place to ensure that the
    provided seat belts were worn when persons
    operated mobile equipment.

Best Practices
  • Stop, Look, Analyze, and Manage ( SLAM ) each
    task to identify all possible hazards. Initiate
    action so the task can be safely performed.
  • Always inspect dumping locations prior to dumping
    the first load. Where material has been loaded
    out of the stockpile or where ground conditions
    may fail to support the weight of the mobile
    equipment, loads should be dumped a safe distance
    back from the edge.
  • Maintain berms or similar impeding devices at
    dumping locations where there is a hazard of
    overtravel.
  • Fasten your seat belt every time you operate a
    truck or self-propelled mobile equipment.
