Facts about flammable and combustible liquids. Flammable and combustible liquids ignite easily and burn with extreme rapidity. Flammability is determined by the flash point of a material. Flash point is the minimum temperature at which a liquid forms a vapor above its surface in sufficient concentration that it can be ignited.
‹ Flammable Liquid Properties up Flammable and Combustible Liquid Storage Considerations › Hazard classifications National Fire Protection Association (NFPA) hazard classifications for flammable and combustible liquids are listed below:
2. What are common examples of the various flammable and combustible liquids classified by NFPA 30? Class IA ‐ Diethyl Ether, Ethylene Oxide, some light crude oils Class IB ‐ Motor and Aviation Gasolines, Toluene, Lacquers, Lacquer Thinner Class IC ‐ Xylene, some paints, some solvent‐based cements
Storage of flammable and combustible liquids is usually a necessity. Whenever flammable and combustible liquids are stored improperly, however, they become a significant fire hazard. For instance, NFPA ® 30: 17.6.9 prohibits Class I flammable liquids from being stored in a basement. 29 CFR 1910.106 has established the following storage ...

NFPA Classifications of Flammable and Combustible Liquids 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. NFPA 30, Flammable and Combustible Liquids Code, published by the National
Flammable & combustible liquids overview. The two primary hazards associated with flammable and combustible liquids are explosion and fire. Flammable liquids are particularly hazardous due to their ability to produce vapors. This vapor mixes with air and burns quickly when the flammable liquid is heated to its flashpoint or above and is ignited.
MATERIAL SAFETY DATA SHEET Hess 5W30 Motor Oil MSDS No. 9683 EMERGENCY OVERVIEW CAUTION! OSHA/NFPA COMBUSTIBLE LIQUID - SLIGHT TO MODERATE IRRITANT EFFECTS CENTRAL NERVOUS SYSTEM HARMFUL OR FATAL IF SWALLOWED Moderate fire hazard. Avoid breathing vapors or mists. May cause dizziness and drowsiness.
Any volatile liquid with a flash point higher than 100 degrees Fahrenheit is considered combustible. Although a handful of motor oils designed for use with motorcycles are flammable, the flash point of most motor oils is at or above 400 degrees Fahrenheit, classifying them as combustible.

Because engine oils have a flashpoint above 150 °C, they are classified as C2 combustibles and not Class 3 Flammable liquids. How to safely store oils Even though engine oils are not classified as class 3 flammable liquids , they must be stored in a safe and compliant manner.
