ABSTRACT:
A method for preventing explosions in closed tanks which hold flammable liquids and flammable vapors and air above these liquid fuels comprising filling the ullage with a pressurized gas which not only excludes oxygen from the ullage but also prevents transmission of fire initiating sparks. The method further comprises filling the ullage with an electronegative gas alone or in combination with an inert gas or gases. More specifically, the preferred electronegative gas is sulfur hexafluoride (SF.sub.6) which may also be used in combination with CO.sub.2 and/or N.sub.2. More particularly, the method is directed to the prevention of explosions in aircraft fuel tanks.
