Question: Protein foam

Answer: A protein-based foam concentrate that is stabilized with metal salts to make a fire-resistant foam blanket. (NFPA 402)

Question: Fluoroprotein foams

Answer: Protein based foam to which fluorochemicals have been added

Question: Film-foaming fluoroprotein foam (FFFP)

Answer: Protein foam solution that uses fluorinated surfacants to produce a fluid aqueous film for supressing liquid fuel vapors

Question: Aqueous film forming foam (AFFF)

Answer: A concentrated aqueous solution of one or more hydrocarbon and/or fluorochemical surfactants that forms a foam capable of producing a vapor-suppressing, aqueous film on the surface of hydrocarbon fuels. (NFPA 403)

Question: Alcohol resistant foam

Answer: -similiar to AFFF but formulated so alcohols and polar solvents do not dissolve foam

Question: Compressed air foam system (CAFS)

Answer: A system that combines foam concentrate, water, and compressed air to produce foam that can stick to both vegetation and structures.

Question: Compressed air foam (CAF)

Answer: Class A foam produced by injecting compressed air into a stream of water that has been mixed with 0.1 percent to 1.0 percent foam.

Question: Foam proportioner

Answer: Device that introduces foam concentrate into the water stream to make the foam solution.

Question: Foam eductor

Answer: A device placed in the hose line that draws foam concentrate from a container and introduces it into the fire stream.

Question: Foam injectors

Answer: Add the foam concentrate to the water stream under pressure.
