A great resource of information on the subject of combustible dust is a blog provided by the Combustible Dust Policy Institute. They site that in 2008, information obtained through media reports indicated 200+ combustible dust related fires and explosions in the grain, manufacturing, utility and non-manufacturing sectors. Their goal on this complex subject is to bring forth a situational awareness to all stakeholders, which will hopefully lessen the occurence and reduce the severity of future accidents.
If you need to get an industrial dust collection system for your shop or factory and suspect that your dust is flammable or explosive, visit and follow the Combustible Dust Policy Institute Blog.
