The victim had been assigned to do miscellaneous clean up throughout the plant and became entangled while carrying out his duties.

  • September 23, 2002, a 43 year-old plant operator with 17 months experience was fatally injured at a crushed stone operation. The victim was removing fines that had packed around a winged tail pulley of a belt that had been buried by spillage. As the spillage was removed, the bound conveyor belt moved backward a short distance and caught the victim's arm between the belt and the tail pulley.
