What is Film Forming Fluoroprotein Foam (FFFP) best described as?

• A. Foam concentrate that combines the qualities of fluoroprotein foam with those of aqueous film forming foam.
• B. Finished foam after air is introduced into the foam solution.
• C. Protein foam with synthetic fluorinated surfactants added; these surfactants enable the foam to shed from hydrocarbon fuels.
• D. A device that injects foam concentrate into the water stream.

Answer: (A)

Film Forming Fluoroprotein Foam is a foam concentrate that blends the film-forming and spreading benefits of fluoroprotein foams with the wetting and film-forming characteristics of aqueous film forming foams. The fluorinated components help the foam form a continuous film on hydrocarbon fuels, improving spreading, cooling, and burn-back resistance. That combination is exactly what the description in the correct choice conveys: a concentrate that merges fluoroprotein qualities with aqueous film-forming foam.

The other descriptions describe either the finished foam after mixing air into it, a protein foam with fluorinated surfactants (which doesn’t emphasize the film-forming blend), or a device that injects concentrate into water, none of which capture the essence of FF FP as a concentrate designed to provide film-forming properties on fuels.
