Firefighting foam - Wikipedia
Firefighting foam is a foam used for fire suppression. Its role is to cool the fire and to coat the fuel, preventing its contact with oxygen, thus achieving suppression of the combustion. Firefighting foam was invented by the Moldovan engineer and chemist Aleksandr Loran in 1902. [1]

Fire Fighting Foams - Chemguard
FOAM: A fire fighting foam is simply a stable mass of small air-filled bubbles, which have a lower density than oil, gasoline or water. Foam is made up of three ingredients - water, foam concentrate and air.
Fire-fighting foam is a stable mass of small bubbles of lower density than most flammable liquids and water. Foam is a blanketing and cooling agent that is produced by mixing air into a foam solution that contains water and foam concentrate. Excludes air from the flammable vapors. Eliminates vapor release from fuel surface.

Firefighting Foams Explained: Action, Expansion and Application
Dec 3, 2019 · Fire-fighting foam acts in two phases, insluation and cooling. Insulation stops the airflow and prevents the combustible from evaporating, taking away the oxidising agent. Cooling removes or decreases the energy that combustion requires as the water in the bubbles decants and evaporates.
