Mine Safety and Health Administration MSHA Comments . FM Global Research has been working on conveyor belt flammability testing for loss prevention purposes, both inplant and underground for several years. We feel that there should be consideration of additional testing methodologies accepted for conveyor belt flammability and smoke generation.
Fire Resistance of Conveyor Belts. Conveyor belt fires can present a serious hazard in the confined environment of an underground coal mine. To minimize this hazard, Federal regulations were enacted following the Federal Coal Mine Health and Safety Act of 1969 to require the use of acceptable fire-resistant conveyor belts and suitable belt slippage-sequence switches, fire warning devices, and ...
Several of the ASTM flammability tests are specified in this chapter with respect to the evaluation of specific materials. Materials used in the U.S. mining industry are regulated for flame resistance by the U.S. Department of Labor, Mine Safety and Health Administration.
2018-7-19 Sustained friction heat generated by the conveyor belt slipping over a stationary pulley or idler results in a large conveyor belt surface area releasing combustible gases, toxic gases and smoke. When ignition point is reached, the conveyor belt will inevitably burst into flames. Legislation and Best Practices MINE HEALTH AND SAFETY ACT ...

CDC - Mining - Flammability of Wider Conveyor Belts - NIOSH. The research conducted to establish the correlation of the BELT with large-scale belt fire flammability tests was done using 91-107 cm 36-42 in wide conveyor belt. Due to todays coal haulage capacity, the mining industry is using 183 cm 72 in and wider conveyor belts.
Underground safety of conveyor belts. Conveyor belts represent a high risk, because they have the ability to spread a fire over long distances. Fires on belt conveyors are mostly ignited by mechanical failures like frozen idlers, which is even more dangerous in combination with coal dust.
