Cooking oil and the extinguishing agent combine to produce saponification, which creates a soapy foam blanket that separates fuel and oxygen.
<h3>What takes place when you add foam to a fire?</h3>
These are the ways foam functions: The foam smothers the flames by covering the fuel surface. The foam covering keeps the fuel surface and the flames/ignition source apart. Foam cools the fuel as well as any nearby metal surfaces.
