FIRE-FIGHTING FOAMS FOR FLAMMABLE LIQUID FIRES.

Developments over the last 20 years have been centered on the formulation of foam compounds incorporating fluorocarbon surfactants into both protein based foams and synthetic detergent based foaming agents to give the broad range of foams available today. Most foam applications are associated with the protection of potentially large flammable liquid risks considered under three headings: large spill fires; deep fuel, contained fires; fires in water miscible liquids. The types of foams in use today are: film-forming foaming agents; water soluble polymers; fluoroprotein foams.
