On May 22, 2008, Adrian Ortiz Zepeda, equipment operator, age 46, was fatally injured when he fell into an energized portable impact crusher. He was standing in a feeder while attempting to unclog material. Zepeda fell into the crusher that was still operating and was ejected from the discharge belt conveyor. 

The accident occurred because management policies and work procedures failed to ensure that all components of electrically powered equipment were de-energized and blocked against hazardous motion before maintenance was performed.
