What are flammable and combustible materials? Flammable materials can be found as solids, liquids, or gases. Flammable solids can be classified in three categories: desensitized explosives, self-reactive materials, and readily combustible solids.
These classifications are used for determining. the various fire protections requirements for the storage and use of flammable. and combustible liquids referred to in NFPA 30 and other NFPA codes and. standards. The classification system is based primarily on the flash point of the. liquid; that is, the minimum temperature at which sufficient vapor is given off. the liquid to form an ignitable mixture with air. Flammable liquids are classified by NFPA as Class I, which are further sub-. classified, based upon additional criteria that affect fire risk, as Class IA, Class. IB and Class IC - these liquids have flash points below 100 ÂºF (37.8 ÂºC) or less.
