Preventing losses: Fire Resistant Anti Static (FRAS ...

Fire Resistant Anti Static (FRAS) conveyor belts are engineered so that the top and bottom covers of the conveyor belt meet local fire retardancy standards. This means these belts are difficult to ignite and should never be the cause of a fire. Additionally, if ignited by an external fire source, they should minimize the propagation of the fire.

Fire Resistance of Conveyor Belts

Aug 15, 2017· 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 fire suppression systems.
