Dust explosions occur when combustible dusts are suspended in air or some other flammable atmosphere and are subjected to a source of ignition. The severity of a dust explosion depends on many factors, but a principal influence is the particle size becausethe consequences of a dust explosion worsen with decrease in particle size.
