Fire-protection guidelines for: Conveyors transporting coal

2013-5-20  A fire condition within a conveyor system may be considered to be :- ♦ A "static" fire - On a stationary conveyor belt, or within the conveyor mechanism / housing. ♦ A "moving" hazard - Hot or burning coal imported onto a traveling conveyor belt. It has been established that each of the above requires a different form of fire
