Three basic elements are needed for a fire: • Combustible dust (fuel) • Ignition source (heat) • Oxygen (oxidizer) Two additional elements are needed for a combustible dust explosion: Dispersion of dust particles in sufficient quantity and concentration Confinement of the dust cloud An initial (primary) explosion in processing equipment or in an area were dust has accumulated may shake loose more accumulated dust, or damage a dust containment system and may cause one or more secondary explosions that can be far more destructive than the initial explosion.
