Which hazard class in the UN system is specifically designated for flammable liquids?

• A. Class 2
• B. Class 3
• C. Class 4
• D. Class 5

Answer: (B)

The classification of flammable liquids in the UN system falls under Class 3. This category encompasses liquids that can easily ignite under standard conditions, posing a fire hazard during transport and handling. Understanding this classification is crucial for ensuring that appropriate safety measures are implemented when dealing with these materials, including correct labeling, storage, and transport guidelines.

Class 3 substances include a wide range of products, such as fuels, solvents, and alcohols. Effective management of these substances is essential to minimizing risks associated with fire and explosions during their usage or transport. The other classes pertain to different types of hazards; for example, Class 2 includes gases, Class 4 covers flammable solids, and Class 5 relates to oxidizers and organic peroxides, which are not specifically about liquids.
