On September 18, 2013, a 56-year old front-end loader operator with 16 years of experience was killed at a crushed stone operation. The victim was attempting to remove a rock from a pug mill hopper when he was engulfed by the material in the hopper.
- Establish and discuss policies and procedures for safely clearing a hopper.
- Equip hoppers with mechanical devices or other effective means of handling material so persons are not required to work where they are exposed to entrapment by sliding material.
- Install a heavy screen (grizzly) to control the size of material and prevent clogging.
- Task train persons to recognize all potential hazardous conditions and to understand safe job procedures for elimination of the hazards before beginning work.
- Before working on or near equipment, ensure that the discharge operating controls are deenergized and locked out.
- Wear a safety harness and lanyard, which is securely anchored and tended by another person, prior to entering bins, hoppers, tanks, or silos.
