Fabric coatings and methods reduce the toxicity of effluent gases produced by combustion of nonazide gas generating compositions used to inflate vehicle occupant restraint systems. Passing the effluent gases into a coating comprising an alkaline material reduces the concentration of toxic oxides of nitrogen therein. Further, passing the effluent gases into a coating comprising an oxidation catalyst reduces the concentration of carbon monoxide therein.

A method of reducing toxicity in effluent gases produced by combustion of a gas generating composition used to inflate a vehicle occupant restraint device, wherein the gas generating composition comprises a nonazide fuel which produces toxic oxides of nitrogen and carbon monoxide upon combustion, said method comprising the steps of: applying a first coating to a first fabric positioned downstream of the combustion reaction, said first coating comprising at least one alkaline composition which effects a reduction in the concentration of the toxic oxides of nitrogen present in said effluent gases; applying a second coating to the first fabric, said second coating comprising an oxidation catalyst which effects a reduction in the concentration of the carbon monoxide in said effluent gases; and flowing the effluent gases into the coated first fabric.
