It's only DUST! What's the big deal? Under the right conditions, many types of industrial dust, including coal, paper, and wood dust, can ignite and produce a devastating explosion. With our Combustible Dusts course, you'll learn to identify the hazards of combustible dust by using the Dust Fire and Explosion Pentagon. You'll get a clear understanding of dust control and preventions measures as well as dust analysis and explosion risk reduction. Our course will also help identify additional risks and prevention techniques associated with primary and secondary dust explosions.

Learning Objectives

  • Define "combustible dust"
  • Describe the dust fire and explosion pentagon
  • Explain risk reduction
  • Describe explosive factors and effects, and secondary explosions
  • Define damage control

Key Questions

The following key questions are answered in this module:

What is combustible dust?
Dust particles that can catch fire and/or cause an explosion.

What is the combustible dust fire and explosion pentagon?
The fire elements that must be necessary for a combustible dust fire or explosion to occur. They are fuel, oxygen, an ignition source (such as fire or electricity), dispersion of dust particles in a cloud, and confinement of that dust cloud (such as in a room or a vessel).

What are some ways that the risk of a combustible dust fire or explosion can be reduced?
The best way to do this is to ensure that all five elements of the fire and explosion pentagon are not present together at any one time. The two elements that are easiest to control are the fuel source and ignition source.

What factors contribute to the risk of an explosion?
The size of the dust particles, the chemical properties of the dust, the moisture content, and the dispersion of the dust cloud.

What are some ways to reduce the effects of an explosion should one occur?
Installing ventilation, using pressure-relief venting on equipment, using spark/ember detection and extinguishing systems, and using explosion protection systems, sprinkler systems, and other specialized suppression systems.

Sample Video Transcript

Below is a transcript of the video sample provided for this module:

To control the dust that fuels explosions reduce the amount of dust that escapes from process or ventilation equipment. Use filters and dust collection systems. Keep surfaces free of dust. Inspect for dust in open and hidden areas on a regular basis. Use cleaning methods that do not create dust clouds. Use vacuum cleaners approved for dust collection. Locate relief valves away from dust hazards. And develop and implement a hazardous inspection, testing, housekeeping and control program.
