摘要

At approximately 5:35 a.m. on June 4, 2014, Joshua L. Wishard was fatally injured when he was crushed between the upper and lower frame of an impact crusher. Wishard and Chris Wells, Supervisor, were feeding raw scoria (volcanic rock with tiny holes) into the crusher unit when a large rock became lodged in the crusher feeder. Wells and Wishard used an excavator to remove the rock from the crusher. Wells then moved the Caterpillar 300 excavator to the fuel island to be refueled. Wishard started the motor of the crushing unit and raised the upper frame off the safety arm (removing the blocking mechanism) then positioned his body under the raised upper frame. The unblocked upper frame lowered and fatally crushed Wishard. There were no witnesses to the accident.
