Safety
Alert - Working in Proximity to Belt Conveyors
PERMIT TO WORK PTW WORK PERMIT
A miner on a belt move crew was fatally injured while removing a splice pin from a 72-inch mainline conveyor. A belt gripper and a ratchet-style come-along failed, releasing stored energy in a tightly stretched portion of the belt, causing the belting to suddenly become taut and shift upward, pinning the miner between the belt and frame of the belt tailpiece.
Best
Practices During Belt Conveyor Maintenance Block
from Motion
•
Controlling of Stored Energy - Identify, isolate, and control
stored mechanical, electrical, hydraulic, and gravitational energy.
•
Block the Motion - Effectively block the belt conveyor to prevent
movement in
either direction.
•
Belt Tension - Relieve belt tension by releasing the energy at
the take-up/belt storage system. Be aware that some tensile energy may remain.
•
Anchor belt clamping system to substantial belt structures. Use
properly rated engineered belt clamps and come-alongs. Do not use belt grippers
to restrain tensioned
belts.
•
Position the clamp 90 degrees to the belt’s direction of travel, and tie off in line with
the belt’s direction of travel.
•
Position belt splice where it can be safely accessed to avoid pinch points.
•
Maintain Safe Distance - Be aware of the consequences if blocking equipment
fails. Stand in safe locations.
Lock and Tag Out - LOTO
•
LOTO - De-energize electrical power, and lock and tag out the main disconnect before
beginning maintenance. Only the person who installed a lock and tag can remove
them, and only after completing the work.
•
Never lock out using the start and stop controls (belt switches). These do
not disconnect power conductors.
•
Try Out - Once power has been disconnected and properly locked and
tagged out, test the system to assure there is no power to the belt
conveyor.
Training and Communication
•
Job Specific Training - Ensure miners are trained on safe work
procedures. Develop step-by-step procedures and review them with all miners
before they perform non-routine maintenance tasks such as adding or removing
conveyor belt.
•
Communicate effectively. After maintenance has been completed and before
removing your lock and tag, ensure everyone is clear of the belt conveyor and
communicate to others that you will be restarting the belt.
