DUST EXPLOSION

How does a dust explosion occur?

It is caused by a combination of five factors:

  • Combustible dust
  • Oxygen
  • Ignition source
  • Sufficient dust concentration
  • Confinement in a space


Due to their large surface area relative to their volume, finely dispersed particles burn extremely quickly. During ignition, pressure waves are created that stir up more dust, thus triggering a self-reinforcing chain reaction.
