Hazard Class 3 is associated with which type of material?

• A. Gases
• B. Toxic and infectious substances
• C. Miscellaneous
• D. Flammable liquids

Answer: (D)

Hazard Class 3 covers flammable liquids—liquids with a flash point low enough to ignite in air during normal handling. This is what the classification communicates to responders and handlers: these liquids pose a fire and explosion risk and require specific precautions, such as controlling ignition sources and using appropriate extinguishing methods. Examples include gasoline, certain solvents, and other fuels. The other options point to different classes: Gases are a separate class for flammable or nonflammable gases; Toxic and infectious substances belong to a class focused on poisons and pathogens; Miscellaneous is a catch‑all for materials that don’t fit other categories. So the material described as Class 3 is specifically flammable liquids.
