A fire suppressing gas generator includes a cylindrical housing comprising an array of discharge ports distributed generally uniformly therearound; a cylindrical filter disposed within the housing and spaced from the interior wall of the housing; a plurality of azide-based propellant grains inside the cylindrical filter; and at least one ignition device associated with the propellant grains. The propellant grains when ignited by the ignition device generate a fire suppressing gas which passes through the filter and out of the discharge ports of the cylindrical housing for delivery into a space.

System and method for sodium azide based suppression of fires

A fire suppression apparatus includes a canister containing a non-azide solid propellant chemical that generates an oxygen-displacing gas mixture when ignited; a pyrotechnic device associated with the canister for initiating ignition of the solid propellant chemical to generate the oxygen-displacing gas mixture; and at least one filter associated with the canister for filtering out contents of the oxygen-displacing gas mixture to result in a clean agent fire suppressant deliverable into a space. The fire suppression apparatus is preferably configured for use in fire suppression systems for normally occupied spaces.

System and method for suppressing fires

A method and apparatus for suppressing in a space includes structure and/or function for generating a first oxygen displacing fire suppressing gas mixture from at least one non-azide solid propellant chemical, the first fire suppressing gas mixture having at least a first gas. The first gas comprises nitrogen. At least the first gas is delivered into the space, thereby delivering a clean agent fire suppressant into the space that reduces the concentration of oxygen in the space to below a level necessary to sustain combustion. Preferably, the method and apparatus are used in inhabited spaces.

A method and apparatus for suppressing a fire utilizing non-azide solid gas propeilant generation to produce and transport a suitable gas for suppressing a fire in a normally occupied area. The nitrogen gas produced by the solid propellant gas generation is optionally treated to remove undesirable elements such as water and/or carbon dioxide from the product gas prior to the delivery of the product gas to the protected hazard area.
