- Review maintenance procedures to ensure all possible hazards have been identified and appropriate controls are in place to protect miners.
- Make sure everyone is positioned so they are not exposed to the hazards.
- Support or block all components against motion, and personally lock out and tag out equipment.
- Make sure that proper equipment and tools are provided and used, and that everyone is trained in safe work procedures.
