Elements of a Combustible Dust Explosion (The Fire and Explosion Pentagon)

Elements of a Fire:

  1. Combustible Dust (fuel);
  2. Ignition Source (heat);
  3. Oxygen in the air (oxidizer);

Additional elements needed for a Combustible Dust Explosion:

  • Dispersion of particles in sufficient quantity and concentration
  • Confinement of a dust cloud

Basically any combustible material and some considered non-combustible (your fuel) in the right concentration suspended in the air could lead to an explosion with potentially deadly consequences
