Best Practices
- Task train persons to recognize all potential hazardous conditions and to understand safe job procedures for elimination of the hazards before beginning work.
- Train miners in safe work procedures and hazard recognition, specifically when clearing blocked hoppers.
- Ensure employees use proper housekeeping procedures in order to avoid extraneous trash from inadvertently entering feed hoppers.
- Establish and discuss policies and procedures for safely clearing hoppers.
- Equip hoppers with mechanical devices, grates/grizzlies or other effective means of handling material so persons are not required to work where they are exposed to entrapment by sliding material.
- Before working on or near equipment, ensure that the discharge operating controls are deenergized and locked out and ensure that material cannot discharge when the feeder is not activated.
- Wear a safety harness and lanyard, which is securely anchored and tended by another person, prior to entering bins, hoppers, tanks, or silos.

On September 21, 2016, a 52 year old contract drill operator / mechanic, with more than 30 years of experience, was killed at a limestone mine while performing maintenance on a truck-mounted rotary drill. At the time of the accident, the victim was attempting to remove the spindle cap from the top of the drill head while standing on the drilling deck. The victim was using a modified pipe wrench in an attempt to loosen the spindle cap using the machine’s drill rotation hydraulics by reaching into the operator’s compartment. As the victim activated the drill rotation lever, the wrench swung and struck him. The force of the impact knocked him against the operator’s cab, denting the frame and breaking the side window while the rotating wrench pierced his abdomen. As the victim attempted to climb down an adjacent step ladder, he was observed falling to the ground and striking his head. The victim was transported to a local hospital and died later that day as a result of his injuries.
