Abstract
There is disclosed an apparatus for suppressing a fire. The apparatus includes a gas generator containing as a propellant, a mixture of a fuel, strontium nitrate as an oxidizer, and magnesium carbonate. When the propellant is ignited, a nitrogen rich effluent is generated that is effective to suppress the fire. By providing the propellant with at least 35%, by weight, of magnesium carbonate, the generation of effluent by-products that are corrosive to aluminum is inhibited.
