Gas generating compositions containing or including a sufficient quantity of a non-nitrate containing ammonia source whereby, upon reaction of the gas generating composition, NOxproducts are present in the product gas in a reduced amount as compared to reaction product gas resulting from reaction of the same composition without said quantity of non-nitrate containing ammonia source. Also disclosed are associated methods of reducing NOxproducts present in an effluent of a gas generating composition that upon combustion forms gas useful for inflating a vehicle occupant safety restraint device.
