The Technical Assesment of Materials liable to Dust Explosion
: Any combustible solids, when divided into a sufficiently fine condition, may give rise to a dust explosion. Many of the dusts handled in industry are combustible and serious dust explosion incidents have occurred in this country. This safety document reviews the testing methods and explosibility assessment of industrial dusts, established in various countries. The testing is to evaluate some of the explosion hazard parameters: explosibility limits, ignition temperature, minimum ignition energy, explosion limit oxygen concentration, maximum explosion pressure and maximum rate of pressure rise. The parameters are grouped in two categories: explosion sensitivity and explosion severity.
