Accidents involving conveyer belt systems injure and kill miners every year. Stay safe by following these best practices.
Guarding to Prevent Contact
•Fabricate and install substantical, durable guards that cannot be easily bypassed to prevent contact with conveyor drives, pulleys or other moving machine parts.
•Keep guards securely in place while conveyors are operating or energized.
•Lock out and tag out power switches before opening or removing guards.
•Ensure guards do not pose a hazard – no sharp edges or points.
•Paint guards a consistent, recognizeable color.
Lock-out and Tag-out
•Place the circuit breaker in the off position and apply your lock and tag to prevent anyone else from turning on the power.
•At power centers in underground coal mines, place the circuit breaker in the off position, remove the cable plug from the receptacle and apply your lock and tag to the cable plug to prevent anyone else from re-energizing it.
•Test equipment to be sure it is de-energized.
•Keep the key while working.
•Personally remove the lock after the work is completed.
Block Against Motion
•Identify and control stored energy: mechanical, electrical, hydraulic, and gravity.
•Release energy at the take-up system to relieve belt tension.
•Use securely-anchored belt clamps to isolate stored energy from the work area, and test them before working.
•Never attempt to cross a moving conveyor except at a designated safe crossing.
•Provide and maintain well-constructed crossovers with handrails at strategic locations.
•Keep adjacent walkways clear. Provide emergency stop cords so the drive motor can be readily deactivated.
•Examine crossing facilities and test functionality of start/stop switches and remote start warnings during belt examinations.
Safety awareness is ESSENTIAL when working with CONVEYOR BELT SYSTEMS.
•Never perform work on a moving conveyor.
•Provide stop and start controls at areas where miners must access both sides of the belt.
•Install audible and visible alarms at belt drives and other places where miners routinely work.
