Combustible dust: a rare but deadly hazard

It is difficult to imagine a construction work site—especially one involving roof system removal and/or installation—without a fair amount of visible dust. Environmental, health and safety professionals rightly focus on hazards related to dust generated from cutting products containing sand; asbestos fibers in dust created during demolition or installation operations; and a variety of other dusts that pose risks to workers.

However, some recent manufacturing-related incidents have drawn attention to the risks associated with another type of dust that—though rare at construction work sites—can have catastrophic effects: combustible dust.

Different from other dust types, combustible dust's significant hazard is not related to worker inhalation, absorption or ingestion of dust but fire and explosion hazards associated with dust.
