In the ten months since early September 2018, MSHA has documented nine equipment fires involving Hitachi excavators and shovels and Caterpillar haul trucks, front end loaders and dozers. On September 7, 2018, a miner received fatal burn injuries when a fire occurred on a haul truck and the manually-activated fire suppression system did not function when activated. The remaining eight equipment fires were all reported as non-injury.
