Fluoroprotein foams

Fluoroprotein foam is available as concentrates for proportioning with water to a concentration of 3% or 6%. The manufacturer should be consulted for the correct concentrate to be used in a particular system. Proportioners, the devices that meter the concentration, must be designed and set for the percent of foam liquid concentrate to be used. 

Fluoroprotein foam is produced through the turbulent mixing of atmospheric air into the foam solution (water and foam liquid concentrate). This turbulence is typically produced by air introduced into the solution by venturi action (foam maker). 

The foam produced with Aqueous Film Forming Foam (AFFF) concentrate is dry-chemical compatible. Protein and fluoroprotein foam concentrates and AFFF concentrates are incompatible and should not be mixed although foams separately generated with these concentrates are compatible and can be applied to a fire in sequence or simultaneously. AFFF is available in various liquid concentrate percentages.

Foam extinguishers, identified by a pale cream panel, contain either AFFF (aqueous film forming foam), FFFP (film forming fluoroprotein foam) or FPF (fluoroprotein foam). These types of extinguishers all form a foam blanket over the fire which excludes the oxygen but their contents react...

Protein foam concentrates are produced by hydrolysis products of proteinaceous matter, such as hoof and horn meal, chicken feathers, or fish meal. Fluoro-protein concentrates are protein foam concentrates with fluorinated surfactants added. The fluorinated surfactants add to the cost of the protein-based foam agents but enhance fire-extinguishing efficiency by repelling hydrocarbon fuel when the foam is covered with fuel. Fluoroprotein foam introduced to a base of a burning fuel tank rises through the fuel and extinguishes the fire. The low surface tension allows fluoroprotein foam to move rapidly over a hydrocarbon fuel surface [133-138].
