Flammable Liquids Classes & Categories - Chemical Strategies, Inc.
2019年7月30日 · Flammable liquid classes are designated by the National Fire Protection Agency (NFPA) and there are six classes total based on a liquid’s closed-cup flash point and boiling point: Class IA, Class IB, Class IC, Class II, Class IIIA, and Class IIIB.
Flammable liquids are classified by NFPA as Class I, which are further sub-classified, based upon additional criteria that afect fire risk, as Class IA, Class IB and Class IC - these liquids have flash points below 100 oF (37.8 oC) or less.
Flammable and Combustible Liquid Hazard Classifications
National Fire Protection Association (NFPA) hazard classifications for flammable and combustible liquids are listed below:
Flammable Liquid: A liquid having a flash point below 100°F and having a vapor pressure not exceeding 40 pisa (2.72 ATM). Class I Flammable Liquids have flash points below 100°F and are subdivided as follows: Class I-A Liquids: Have a flash point below 73°F and a boiling point below 100°F. Class I-B Liquids: Have a flash point below 73°F ...

2017年6月22日 · Class 3 covers flammable liquids, which includes some molten solid substances and liquid desensitized explosives. Substances are divided into different packing groups according to the degree of danger they present to transportation. See …
Flammable liquids are referred to as Class 1 Liquids. Class 1 Liquids are separated into the following three categories: (22.88 C), and a boiling point below 1008 F (37.88 C). Examples of this class are Ethyl Ether and Pentane. (22.88 C), and a boiling point of at least 1008 F (37.88 C). Examples of this class are Acetone, Gasoline and MEK.
Flammable liquid means a liquid having a flash point of not more than 93°C (199.4°F). Flash point means the minimum temperature at which a liquid gives off vapor in sufficient concentration to form an ignitable mixture with air near the surface of the liquid. How are flammable liquids classified under OSHA’s HCS? Table 1 shows the ...
