If presence of an ignition source can not be prevented in a fuel tank then a fuel tank can be made inert by ( 1 ) reducing the oxygen content of the ullage ( space above the fuel that contains air and fuel vapors ) below the threshold required for combustion, or ( 2 ) by reducing the air-fuel ratio of the ullage below the minimum threshold ( Lower Flammability Limit ) required for combustion, or ( 3 ) increasing the fuel air ratio above the maximum threshold ( Upper Flammability Limit ) that can support combustion.
