In our last blog, we considered two myths about dust explosions, showing that just because you can’t see the dust doesn’t mean it isn’t there, and just a little dust is necessary for ignition. If you own a facility, it’s important to understand just how dust explosions work so you can protect your property. It’s even more important to get the dust out so you and your employees don’t have to live with the hazard. Our air filtration systems are made to do just that!

In today’s blog, we have one last myth to bust. It’s a sneaky one.

MYTH: Dust needs a high-energy source of ignition in order to ignite

Unfortunately, dust can ignite without the help of a high-energy source. High-energy sources cause the most ignitions, but there are low-energy sources that can catch you by surprise.

  • Impact sparks and electrostatic shocks – these flashes of energy are enough to ignite dust and create an explosion.
  • Self-heating – when dust gets really thick, it can oxidize or decompose, which may heat the area. Dust doesn’t conduct heat; it traps it, which means that the thicker the dust is, the easier it lights up.
  • Hot surfaces – if a surface is already hot, dust will simply insulate it and prevent it from cooling off. The more dust gathers, the more heat is trapped, and the closer you come to ignition.
  • Changing particle size – you may think the dust in your facility isn’t fine enough to ignite. However, as the particles stick around, they may get finer and finer, eventually becoming combustible.

At the end of the day, any processes that creates dust put a facility at risk for sudden combustion. It is absolutely essential to keep your facility free of dust accumulation. Our baghouse dust collectors are made to do just that – and safely. Contact Baghouse America today!
