1. A method of managing the combustion of a primary gas generant within a gas generator of a vehicle occupant protection system, the method comprising the steps of:
- providing an inflator within a vehicle occupant protection system;
providing a primary gas generant composition suitable for use within the inflator; and
providing an autoignition composition in operable communication with the primary gas generant composition, whereby the autoignition temperature of the autoignition composition is less than the autoignition temperature of the primary gas generant composition and heterogeneous thereto, and, the autoignition composition contains carboxylic acid and potassium chlorate.
