COAL MINE FATALITY - On Tuesday, November 28, 2006, a 50-year old haul truck operator was fatally injured while the victim was dumping coal waste material in the spoil dump in Pit 3 West. Condensation in the air lines froze and the brakes would not release. The victim exited the cab of the haul truck. The brakes finally released. The victim sustained fatal crushing injuries when the driver's side rear tandem wheels of the Caterpillar 789B Haul Truck he was operating came to rest on top of him.
When temperatures fall below freezing, drain condensation from air compressors at least every shift. Maintain dryer systems and change out desiccant filters to prevent moisture from accumulating in air hoses and valves. Ensure methanol levels are maintained in methanol air dryers to de-ice lines. Never exit a vehicle without engaging the parking brake.
