Combustible Dust Education & Awareness

The British Columbia Fire Code refers to hazardous locations as being areas in which flammable gases or vapours, combustible dusts or combustible fibres are present in quantities sufficient to create a hazard (Electrical and Gas Codes contain similar references). 

Combustible dust is finely divided solid particles that present a dust fire or dust explosion hazard when dispersed and ignited in air (NFPA 499).  Combustible dust is more accurately referred to as deflagrable dust.  Deflagrable dust is defined (in part) as wood particulate that will propagate a flame front... when suspended in air... regardless of particle size or shape (NFPA 664).
