A nonazide gas generant that may be used in an inflation device, such as a vehicle passenger restraint system, comprising a hydrated or anhydrous mixture of nonazide fuel, an oxidizer and a quantity of copper phthalocyanine, otherwise known as Monarch Blue and/or azodicarbonamidine dinitrate. Specifically, the nonazide gas generant composition of the present invention may include phase stabilized ammonium nitrate (PSAN), high bulk density nitroguanidine (HBNQ), one or more nonazide fuels, a quantity of copper phthalocyanine and/or azodicarbonamidine dinitrate and optionally a binder. The gas generant composition of the present invention is capable of self-sustained burning at low or ambient temperatures and pressures, important for use in dual stage "smart" inflator automotive passenger restraint systems, while exhibiting a relatively high gas volume to solid particulate ratio upon combustion at acceptable flame temperatures. The composition also exhibits a tailorable burning rate and properties to preclude catastrophic events during cook off tests.
