An apparatus and method for inflating a vehicular inflatable device are provided wherein inflation gas is produced via a dissociative material wherein an initiator includes an enhanced fuel pyrotechnic formulation which, in addition to initiating dissociation of at least a portion of a quantity of gas source material contained within the inflator, forming dissociation products used to inflate the device, also forms particles to interact with one or more of at least a portion of the remaining quantity of gas source material contained within the inflator and the dissociation products to form additional inflation products for inflating the inflatable device.
