- Train miners and contractors on reactive material hazards and clean out procedures prior to performing repair work.
- Conduct job‑specific hazard assessments and follow manufacturer recommendations for auger removal, repair, and welding activities.
- Ensure all stored energy sources, including mechanical, electrical and thermal are locked out, tagged out, and secured against motion before removing or repairing augers or drive components.
