Methods for producing a gas generator for a vehicle occupant restraint system with an autoignition means are disclosed. The autoignition composition used in the method preferably comprises Pb(SCN).sub.2 and chlorate oxidizer which undergo rapid autoignition at temperatures from approximately 190.deg

Methods for producing a gas generator for a vehicle occupant restraint system with an autoignition means are disclosed. The autoignition composition used in the method preferably comprises Pb(SCN).sub.2 and chlorate oxidizer which undergo rapid autoignition at temperatures from approximately 190.degree.-220.degree. C. The inventive method provides for the use of aluminum for the gas generator housing. Through the method of this invention, autoignition compositions are safely manufactured by wet blending and are installed via automation in the interior of the inflator housing. When aluminum housings are used, a barrier material is used to prevent corrosion of the aluminum by the autoignition composition. Optionally, the dried autoignition material is coated with a protective substance to prevent water absorption and mechanical abrasion.
