Abstract
Fire extinguishing or suppression apparatus and method employing a liquid pyrotechnic composition of a ternary mixture of hydroxyl ammonium nitrate, an amine nitrate salt, and water, in a closed combustion chamber of a pressure container. The apparatus is constructed to permit a large volume of water vapor exothermically generated by the reaction of a liquid pyrotechnic composition to be discharged from the combustion chamber and pressure container to an area of a fire.
