According to the United Nations, flammable liquids are classified under which class?

Flammable liquids are classified under Class 3 according to the United Nations classification system. This classification is essential for the safe transportation and handling of hazardous materials, as it helps to identify the risks associated with flammable substances. Class 3 encompasses liquids with a flash point of not more than 60 degrees Celsius (140 degrees Fahrenheit), indicating that these liquids can easily ignite and pose a significant fire hazard. The clear definition of Class 3 allows for appropriate precautions during storage, transportation, and use, ensuring safety for both individuals and the environment.

The other classes referenced do not pertain to flammable liquids. Class 1 typically includes explosives, Class 5 pertains to oxidizing substances and organic peroxides, and Class 7 is designated for radioactive materials. Each of these classes has distinct characteristics and safety measures that do not apply to flammable liquids, emphasizing the importance of accurate classification in hazardous material management.
