Safe coal handling practices are designed to ensure that the fuel remains intact throughout its journey from the mine until the point at which it is ignited in the boiler. It takes as little as 1.4 kg (3 lbs) of pulverised coal in 28 m3(1,000 ft3) of air to form an explosive mixture.
Hot surfaces such as hot bearings, cutting, or welding can start a coal dust fire or explosion. Any unusual temperatures must be reported immediately and steps taken to solve the problem. Cutting and welding around the coal mill system should only be done under strict supervision by qualified personnel.

To evolve uniform safety procedure in Operation and Maintenance of Coal Conveyors Belts for ensuring the safety in O & M in Coal Handling Plants. 2. SCOPE: This procedure applies to different types of conveyors used in coal handling plants in all operating sites of Tata Power Group companies
The design and operation of fuel handling and burning equipment must provide for maximum personnel safety and minimal property damage in the event of a coal/ air fire or explosion. In gas and oil fuel handling systems, explosive mixtures are minimized by keeping the air and fuel separate until they are combined at the point of combustion.

coal or rock bursts, in underground coal mines. Each underground coal mine operator is required by 30 CFR . 75.220(a)(1) to develop and follow a roof control plan approved by the Mine Safety and Health Administration (MSHA) District Manager. The plan must be suitable to the prevailing geological conditions and the mining system used at the mine.
