Which of the following is the Film Forming Fluoroprotein foam (FFFP) type?

• A. Protein foam
• B. Fluoroprotein foam
• C. Film forming fluoroprotein foam (FFFP)
• D. Aqueous Film Forming Foam (AFFF)

Answer: (C)

Film Forming Fluoroprotein Foam is the type that explicitly combines a protein base with fluorinated surfactants capable of forming a persistent surface film on the fuel. This film helps seal the surface, suppress vapors, and improve burnback resistance, making extinguishment more effective on hydrocarbon fires. The other foams differ in composition or behavior: ordinary protein foam lacks the fluorinated film; fluoroprotein foam adds fluorinated agents but doesn’t always form the specialized surface film; AFFF is a synthetic fluorinated foam without a protein base. So the term that matches the described category is the film forming fluoroprotein foam.
