Combustible Dust Sign
A wide variety of materials can be explosive in dust form, including:
- foodstuffs (sugar, starch, flour, feed)
- metals (aluminum, chromium, iron, magnesium, zinc), and
- fossil fuel power generation.
Combustible dusts include fine particles, fibers, chips, chunks or flakes that - under certain conditions - can cause a fire or explosion when suspended in air. OSHA's Combustible Dust Web page provides additional information and resources for preventing and minimizing the effects of combustible dust fires and explosions.
