FIGHTING FIRE Abstract of the Disclosure Fire-fighting foam effective against burning hydro- philic or polar liquids like lower alcohols, ketones, etc. is made from concentrate containing thixotropic thickener dissolved in large amount, yet has a tolerable viscosity particularly when stirred. Heteropolysaccharide-7 or chain-shortened modifications of it are suitable for this purpose. The concentrate can also be made suitable for fighting fires on hydrophobic liquids by adding surfactants that cause aqueous film formation over such liquids.
