Arlington, VA — Spurred by recent deaths and injuries caused by the sudden release of energy from belt conveyor systems, the Mine Safety and Health Administration has issued a safety alert.
MSHA describes two fatal incidents since 2019. In one, equipment on a longwall belt conveyor broke and struck a belt foreman. The other incident occurred when a worker got caught between a 72-inch-wide belt and the steel frame of its tailpiece.
Best practices for safe operation include:
- Develop safe work procedures – including lockout/tagout, blocking against motion and securing the belt conveyor – that eliminate or safely control stored energy in belt conveyors.
- Ensure belt conveyor moves, maintenance and repairs are performed with the correct replacement parts, proper tools and suitable rigging.
- Educate miners on the safety aspects and safe work procedures for moving, maintaining and repairing belt conveyors.
- Instruct miners to stay in safe locations while in a belt conveyor entry – away from the belt drive and take-up winch – when starting or stopping the belt.
- Install properly designed safety restraints for moving parts such as movable carriages, bridles and take-up sleds in case primary components fail.
- Perform a risk assessment before beginning work to identify and control stored energy: mechanical, electrical, hydraulic and gravity.
