A method and apparatus for dispensing a liquid, such as a fire suppressing agent, with a gas wherein both the liquid and a combustible propellant for generating the gas are stored in separate sealed compartments at atmospheric pressure. The liquid is stored in a chamber between an annular piston and a central pedestal containing a gas generating canister. A portion of the gas generated drives the piston to expel the liquid into a mixing chamber in the pedestal, and another gas portion is fed into the mixing chamber so as to mix with and propel the liquid through a nozzle. The liquid may be atomized or vaporized depending on its composition. Mixing of the liquid with the gas may be enhanced by tangentially injecting the liquid into the mixing chamber.
