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.
