  2. Overview The victim was killed while he was cleaning an unguarded return idler inside the frame of a mobile stacking belt conveyor that was five feet above the ground. He became entangled between the return idler and the belt. The accident occurred due to management’s failure to establish safe work procedures to be followed while persons performed work on the belt conveyor. The victim was using a tool to clean the unguarded return idler while the belt conveyor was in motion. The belt conveyor was not deenergized and blocked against motion before the victim attempted to remove the spillage on the return idler.

  3. Root Cause Root Cause: Management did not ensure that appropriate safe work procedures were established for persons to safely clean and maintain the belt conveyor. The belt conveyor was not deenergized and locked out and tagged out before the victim performed work. Corrective Action: Management developed a standard operating policy (SOP) regarding the belt conveyor’s cleanup and maintenance, as well as a detailed Lock out/Tag out policy that requires persons to deenergize the equipment and ensure the equipment is locked out and tagged out. The SOP was explained and miners who work in the reclamation area were trained on the procedures. Additionally, management required that all of the bottom return idlers under the belt conveyor be guarded the entire length of the belt.

  4. Best Practices • Establish policies and procedures for conducting specific tasks on belt conveyors. • Before beginning any work, ensure that persons assigned to clean belt conveyors are task trained and understand the hazards associated with the work to be performed. • Do not perform work on a belt conveyor until the power is off, locked, and tagged, and machinery components are blocked against motion. • Never clean pulleys or idlers manually while belt conveyors are operating. • Identify hazards around belt conveyor systems, design guards, and securely install the guarding to ensure miners do contact moving parts.
