Some recent accidents occurred when vehicles flipped over backwards, rolled over, and tipped over on their sides. Miners were operating haul trucks, excavators, bulldozers, front end loaders, and service trucks while working or traveling near the edge of dump sites, elevated roadways, embankments, ponds, and excavations.
Contributing factors included the non-use or unbuckling of seat belts; jumping from vehicles; brake failure; distracted driving; loss of vehicle control; traveling or working too close to unconsolidated roadways; inadequate berms; pushing through berms; and failure to perform workplace examinations.
