Which hazard class is associated with acetone, gasoline, and similar solvents?

• A. Class 3 (flammable liquids)
• B. Class 2 (gases)
• C. Class 4 (flammable solids)
• D. Class 9 (miscellaneous hazards)

Answer: (A)

Flammable liquids are those that can form ignitable vapors at relatively low temperatures. Acetone and gasoline fit this category because they have very low flash points, meaning their vapors can ignite with a small ignition source. Acetone’s flash point is around -20°C and gasoline’s is well below that, so they can ignite in normal environments when mixed with air. In hazmat terms, liquids with flash points at or below 60°C are classified as flammable liquids, which is why acetone and gasoline fall into this class. They are liquids, not gases, so they are not Class 2. They are not solids, so they are not Class 4. They aren’t miscellaneous hazards that would fall under Class 9. So the hazard class associated with acetone, gasoline, and similar solvents is flammable liquids.
