Which Hazard Class would cover Liquids?

• A. Class 1
• B. Class 4
• C. Class 9
• D. Class 3

Answer: (D)

Liquids that pose a fire hazard are categorized as Class 3, flammable liquids. Hazard classes group materials by their primary danger so labeling, packaging, and transport can be managed consistently. Flammable liquids include fuels and many solvents because their liquid state and low flash points make them readily ignitable. Other classes in the options address different hazards or states: explosives involve highly energetic materials, flammable solids are burnable solids, and Class 9 covers miscellaneous dangerous goods that don’t fit other categories. So for liquids that burn, Class 3 is the appropriate classification.
