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]

What is Firefighting Foam and Why do Firefighters Use it?
When firefighting foam is used on a fire, the foam blanket smothers the fire, removes oxygen, reduces heat, and creates a barrier that mitigates vapor release. In essence, foam acts as a versatile tool that tackles the components of the fire tetrahedron (oxygen, heat, fuel) from various angles, enabling more efficient fire suppression.
