Aqueous film forming foam is used for?

• A. Suppressing Vapors of Flammable Liquids
• B. Providing Color in Foam
• C. Cleaning
• D. Cooling Spilled Liquids

Answer: (A)

Aqueous film forming foam is designed to suppress vapors from flammable liquids by forming a thin, stable film on the surface that blankets the fuel and cuts off contact with air. This film reduces vapor release and helps prevent ignition, allowing firefighters to control the spill effectively. The cooling effect comes from the water in the foam, but the main purpose is vapor suppression and fire control on hydrocarbon fuels. The other options miss the primary function: color in foam isn’t a safety feature, cleaning isn’t the main goal, and although cooling occurs, it’s not the core reason for using this foam.
