A prescriptive DHA was conducted and it indicated the indoor dust collectors likely presented a combustible dust explosion hazard and would require explosion protection and explosion isolation per NFPA 652 § 9.3.4 and 9.7. Upon further evaluation, it was determined that a performance-based approach could be implemented to determine if existing. Combustible dust is a finely divided combustible particulate solid that presents a flash fire hazard or explosion hazard when suspended in air. These tiny particles of material might not normally be flammable, but when suspended in a cloud, they can be ignited and cause a dangerous chain reaction. Every manufacturing facility is vulnerable. In addition, a combustible particulate solid is defined as: Any solid material composed of distinct particles or pieces, regardless of size, shape, or chemical composition that presents a fire hazard. Examples of combustible dust: Metal Dust - Such as Aluminum and Magnesium. Wood Dust. Coal and Other Carbon Dusts THE DUST EXPLOSION PENTAGON Historically, one of the difficulties in controlling combustible or explosive dust hazards is defining exactly what constitutes a combustible or explosible dust atmosphere. Five elements are needed for a combustible dust explosion to occur: fuel (combustible dust), an ignition source (a flame, spark, or hot surface.
