Surface - Limestone – On October 22, 2017, a miner was working on clearing a jammed primary crusher.  While using an air hammer to break up a large rock, another rock became dislodged and slid down, pinning the miner’s feet.  After being pinned for nearly an hour, the victim was freed and taken to a nearby hospital for observation. 

Best Practices
  • Establish policies and follow manufacturer’s recommended procedures for conducting specific tasks on crushers.  Implement measures to ensure miners are positioned safely and protected from hazards while performing the task.
  • Task train persons to recognize all potential hazardous conditions and to understand safe job procedures for elimination of the hazards before beginning work.
  • Do not work below unsecured material.
  • Remove excess material by mechanical means where possible before the cause of the blockage can be dealt.
  • When removal of material by hand is necessary, the crusher and associated plant must be stopped and isolated
  • Manual removal should only be carried out by suitably trained and competent persons
