An Introduction to Dust Explosions
Understanding the Myths and Realities of Dust Explosions for a Safer Workplace
- Paul Amyotte, Professor of Chemical Engineering and C.D. Howe Chair in Engineering, Department of Chemical Engineering, Process Engineering & Applied Science, Dalhousie University, Canada.
An Introduction to Dust Explosions describes the main erroneous beliefs about the origin and propagation of dust explosions. It offers fact-based explanations for their occurrence and the impact of such events and provides a critical guide to managing and mitigating dust explosion risks.

Table of Contents
1. INTRODUCTION: Dust Explosions - Myth or Reality?
2. MYTH NO. 1 (FUEL): Dust does not explode.
3. MYTH NO. 2 (FUEL): Dust explosions only happen in coal mines and grain elevators.
4. MYTH NO. 3 (FUEL): A lot of dust is needed to have an explosion.
5. MYTH NO. 4 (FUEL): Gas explosions are much worse than dust explosions.
6. MYTH NO. 5 (FUEL): It’s up to the testing lab to specify which particle size to test.
7. MYTH NO. 6 (FUEL/IGNITION SOURCE): Any amount of suppressant is better than none.
8. MYTH NO. 7 (IGNITION SOURCE): Dusts only ignite with a high-energy ignition source.
9. MYTH NO. 8 (IGNITION SOURCE): Only dust clouds - not dust layers - will ignite.
10. MYTH NO. 9 (OXIDANT): Oxygen removal must be complete to be effective.
11. MYTH NO. 10 (OXIDANT): Taking away the oxygen makes things safe.
12. MYTH NO. 11 (MIXING): There’s no problem if dust is not visible in the air.
13. MYTH NO. 12 (MIXING): Once airborne, a dust will quickly settle out of suspension.
14. MYTH NO. 13 (MIXING): Mixing is mixing; there are no degrees.
15. MYTH NO. 14 (CONFINEMENT): Venting is the only/best solution to the dust explosion problem.
16. MYTH NO. 15 (CONFINEMENT): Total confinement is required to have an explosion.
17. MYTH NO. 16 (CONFINEMENT): Confinement means four walls, a roof and a floor.
18. MYTH NO. 17 (PENTAGON): The vocabulary of dust explosions is difficult to understand
19. MYTH NO. 18 (PENTAGON): Dust explosion parameters are fundamental material properties.
20. MYTH NO. 19 (PENTAGON): It makes sense to combine explosion parameters in a single index.
21. MYTH NO. 20 (PENTAGON): It won’t happen to me.
22. CONCLUSION: Dust Explosion Realities
