The basic requirements for a dust explosion to occur are that combustible dusts are suspended in air and are ignited. In practice, for a dust explosion to occur, a number of conditions must be met including: The dust must be combustible and release enough heat when it burns to sustain the fire. The dust must be capable of being suspended in air.
