Provide an example of a Class 3 hazmat and its typical placard color.

• A. Gasoline (Class 3); red placard indicating flammable liquid.
• B. Water (Class 9); blue placard.
• C. Ammonia (Class 2); green placard.
• D. Fireworks (Class 1); orange placard.

Answer: (A)

Class 3 hazmat covers flammable liquids, which are identified by a red placard indicating a flammable liquid hazard. Gasoline is a classic example of a flammable liquid, so it fits this category perfectly and uses the red placard to warn responders about the fire risk. The other options don’t fit: water isn’t a flammable liquid and isn’t Class 3, ammonia is a gas (Class 2) and would have a placard signaling a gaseous hazard, not a liquid one, and fireworks are explosives (Class 1) with placards associated with explosives rather than flammable liquids.
