Which class includes Flammable Gases?

• A. Class 4
• B. Class 3
• C. Class 7
• D. Class 2

Answer: (D)

Gases are categorized as Class 2 in HazMat classifications, and flammable gases fall specifically under 2.1, the flammable gases subcategory. The system groups hazards by the material’s state and risk, so all gases share Class 2, including flammable, non-flammable, and toxic gases. The other classes correspond to different hazards: Class 3 covers flammable liquids, Class 4 covers flammable solids, and Class 7 covers radioactive materials. Therefore, flammable gases belong to the gas class, Class 2.
