Combustible dusts are fine particles that present an explosion hazard when suspended in air under certain conditions according to OSHA. However, according to the OSHA Combustible Dust ANPR (Advanced Notice of Proposed Rulemaking), Page 30, "No single, universally accepted definition of combustible dust is available. Even among standard promulgated by the same standards-developing organization, the definitions vary significantly."

First it is important to determine if you have a combustible dust hazard. Under certain conditions wood dust is potentially combustible and does present an explosive dust hazard. However, other dust such as mineral dust is not an explosive dust hazard as it cannot combust. Size and moisture is also important. If you have any doubt, you must send your dust to be tested by certified facility. There are various testing options including a comprehension OSHA Combustible Dust NEP Test designed to meet OSHA National Emphasis Program for Combustible Dust.
