Which foam concentrate uses fluorinated surfactants to produce a film on hydrocarbon fuels?

• A. AFFF
• B. Film-forming fluoroprotein foam concentrate (FFFP)
• C. Alcohol-resistant foam concentrate
• D. Protein foam concentrate

Answer: (B)

The key idea is that fluorinated surfactants are used to create a persistent film on hydrocarbon fuels. A film-forming fluoroprotein foam combines a protein base with fluorinated surfactants, and this setup forms a continuous, heat-resistant film on the surface of the fuel. That film blankets and seals the hydrocarbon surface, promotes rapid spreading to cover the fuel, and helps prevent burnback, making it specifically suited for hydrocarbon fires. This is why the option named “film-forming fluoroprotein foam concentrate” is the best choice.
