Foams and methods of using foams for fighting fires in confined areas (i.e., mine shafts) are provided. In one embodiment, a foam for extinguishing a fire is provided. The foam includes a surfactant; a non-flammable liquid; and an inert gas having a density substantially less than air. Preferably, the density of the foam is substantially less than the density of air. The light foam will allow a basic form of directional control of the foam because the light foam will float towards the ceiling of a cavern or mine shaft. This offers fire fighters several options in extinguishing an underground fire.
