What is combustible dust?Combustible dust is any fine material that has the ability to catch fire and explode when mixed with air. “Combustible dusts are often either organic or metal dusts ground into small particles, fibers, chips, chunks, flakes or a small mixture of these” (OSHA).
Why should I care about combustible dust?If you work in, operate, clean, or manage a manufacturing or processing facility…you should care about combustible dust. In a recent article, the Chemical Safety Board documented 50 combustible dust accidents between 2008 and 2012. The accidents led to 29 fatalities and 161 injuries. Each one involved facilities that didn’t think they were at risk. Each one was preventable.
What types of dust should I look for?There are more dusts that are combustible than not. OSHA has created a poster you can download that details all of the materials that can combust when in powdered form. However, if you work in any of the following industries, you need to pay closer attention to how you clean your facilities:
- Food (sugar, spice, starch, flour, and more)
- Tire and Rubber
- Construction (Manufacturing materials)

- Inform employees of the dangers of combustible dust
