Safe Work Practices • Maintenance should not be performed unless the power is off and machinery components are blocked against motion. • Visible or audible warnings should be provided before conveyor start-up when the entire length of the conveyor is not visible from the starting switch. • Mine operators should take measures to assure all personnel are trained in safe work procedures.
Safe Work Practices • Moving machine parts should be guarded to protect persons from contact that could cause injury. • Conveyors should be provided with emergency stop cords along their entire length. Moving machine parts should be guarded to protect persons. • Clean up in and around moving machinery should not be conducted while the equipment is in operation. • Safe access should be provided to all working areas.
Safe Work Practices • Ensure manufacturer's recommendations are reviewed and miners are trained regarding maintenance tasks prior to beginning work. • Identify and discuss possible hazards and address steps to eliminate them. • Ensure the proper tools are provided and used to complete all required tasks. • Block all equipment or machinery components to prevent possible movement.
