While patrolling the hog fuel conveyor belt system, a worker noticed a piece of wire caught in the nip point between the hog fuel belt and the head spool. He reached into the nip-point area to remove the wire. As he grabbed the wire, his hand was pulled into the nip point. His arm was crushed when it rotated through the nip point and the head spool. The crushing injury resulted in the amputation of his right arm — the injured worker died two days later.
