dust explosion
Low frequencyTechnical / Industrial Safety
Definition
Meaning
A sudden, violent combustion of fine particulate matter suspended in air, causing rapid pressure increase.
A catastrophic industrial accident where combustible dust particles ignite, often in enclosed spaces like grain elevators, coal mines, or manufacturing plants.
Linguistics
Semantic Notes
Refers specifically to combustible dust (flour, coal, metal, sugar) rather than ordinary household dust. Often catastrophic in scale.

Examples
By CEFR Level
- A dust explosion can happen in a flour mill.

Learning
Memory Aids
Mnemonic
Think: DUST = Dangerous Untidy Suspended Traces + EXPLOSION = bang!
Conceptual Metaphor
Sleeping dragon (hidden danger that suddenly awakens with catastrophic force)
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation 'пыль взрыв' – use technical term 'взрыв пыли' or 'пылевой взрыв'.
Common Mistakes
- Using 'dust explosion' for ordinary explosions in dusty environments rather than explosions OF dust itself.

FAQ
Frequently Asked Questions
No, typical household dust (skin cells, fibres) isn't combustible enough. Dust explosions require specific industrial dusts (flour, coal, metals).
Dust explosions involve solid particles suspended in air, while gas explosions involve flammable gases. Dust explosions often have two phases: primary and secondary.
No, dust explosions require an ignition source (spark, hot surface, static electricity) to trigger rapid combustion.
In industries handling bulk powders: grain elevators, flour mills, coal mines, pharmaceutical plants, and metalworking facilities.
