1. A method of suppressing fires in a space comprising the steps of:
- (a) generating a first fire suppressing gas mixture from at least one non-azide solid propellant chemical, the first fire suppressing gas mixture comprising nitrogen and at least one of moisture and carbon dioxide,(b) filtering at least a percentage of said at least one of moisture and carbon dioxide from the first fire suppressing gas mixture to produce a second fire suppressing gas mixture; and
(c) delivering the second fire suppressing gas mixture into the space.

Abstract
A method and apparatus for suppressing a fire utilizing non-azide solid gas propellant 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.

9. A gas generator for generating and delivering a fire suppressing gas mixture to an enclosed space, comprising:
-
a tower; a pre-packed non-azide solid propellant canister disposed within said tower; a pyrotechnic device for igniting said solid propellant canister and thereby generating said fire suppressing gas mixture; a discharge diffuser for directing the fire suppressing gas mixture within said enclosed space; and at least one filter for filtering at least a portion of one gas from said fire suppressing gas mixture. - View Dependent Claims (10, 11, 12, 13, 14)
