Flammability No. Stability Criteria 4 Severe 3 Serious 2 Moderate 1 Slight hazard 0 Minimal Table E-1 HMIS Defined Degrees of Flammability Hazard Materials that rapidly or completely vaporize at atmospheric pressure and normal ambient temperature, or that are readily dispersed in air and readily burn Liquids and solids that can be ignited under almost all ambient temperature conditions; materials that produce hazardous atmospheres with air under almost all ambient temperatures—or, unaffected by ambient temperatures, are readily ignited under almost all conditions Materials that must be moderately heated or exposed to relatively high ambient temperatures before ignition; materials that would not under normal conditions form hazardous atmospheres with air, but under high ambient temperatures or moderate heating may release sufficient quantities of vapor to produce hazardous atmospheres with air Materials that must be preheated before ignition; materials that require considerable preheating for ignition or combustion under all ambient temperature conditions Typically Includes Flammable gases Flammable cryogenic materials Any liquid or gaseous material that is liquid while under pressure and has a flash point below 73°F and a boiling point below 100°F (NFPA Class IA) Materials that ignite spontaneously in air Liquids with a flash point below 73°F and a boiling point at or above 100°F (NFPA Class IB); also liquids with a flash point at or above 73°F and a boiling point below 100°F Materials that—because of physical form or environmental conditions—can form explosive mixtures with air and are readily dispersed in air, such as dusts of combustible solids and mists of flammable or combustible liquid droplets Materials that burn with extreme rapidity, usually by reason of self-contained oxygen (e.g., dry nitrocellulose and many organic peroxides) Liquids with a flash point at or above 100°F but not exceeding 200°F (i.e., NFPA Classes II and IIIA) Solid materials in the form of coarse dusts that may burn rapidly but generally do not form explosive atmospheres Solid materials in a fibrous or shredded form that may burn rapidly and create flash fire hazards, such as cotton, sisal, and hemp Solids and semisolids that readily give off flammable vapors Materials that burn in air when exposed to a temperature of 1,500°F for 5 minutes or less Liquids, solids, and semisolids with a flash point above 200°F (NFPA Class IIIB) Most ordinary combustible materials Materials that do not burn Any material that does not burn in air when exposed to a temperature of 1,500°F for 5 minutes 122
