Explosion depends on an atmosphere of a mixture of flammable material with oxygen. The best approach to prevent fires and explosions is to substitute or minimise the use of flammable material. If that is not possible it is important to avoid effective sources of ignition.
Dust Explosion Prevention A dust cloud of flammable concentration can be produced in industry either by design or by chance. For example, lean-phase pneumatic transfer systems handling flammable dust have an almost continual dust cloud present. In processes such as the filling and emptying of dust containers a dust cloud of flammable concentration is produced transiently.
