Hand-held foam extinguishers used the identical two chemicals in solution. To actuate the extinguisher, a seal was damaged and the unit inverted, allowing the liquids to mix and react. Chemical foam is a secure answer of small bubbles containing carbon dioxide with lower density than oil or water, and reveals persistence for overlaying flat surfaces.

Static installations are concerned in the case of lengthy distance static displays, or basic headed sprinklers. This kind of spray can only be applied to class B fires of the hydrocarbon kind (water-immsicible liquids), utilizing AFFF foam concentrates (Aqueous Film Forming Foam). Expansion is strongly dependent on the type of foam concentrate and the kind of hose used.
