Abstract
There is provided an apparatus for suppressing a fire. The apparatus includes a gas generator charged with a combustive propellant. Upon ignition, the combustive propellant generates a copious volume of gas. The gas is directed by a first conduit to a chamber containing a packed powder that is effective to suppress a fire. A second conduit directs the gas driven packed powder to the fire. In one embodiment, the fire suppressing packed powder is magnesium carbonate.
