An essentially particulate-free, non-toxic, odorless and colorless gas is generated in a pyrotechnic inflator device by using a eutectic solution of ammonium nitrate, guanidine nitrate and/or aminoguanidine nitrate, and minor amounts of polyvinyl alcohol and either potassium nitrate or potassium perchlorate. Ballistic modifiers such as triaminoguanidine nitrate (TAGN) or nitroguanidine (NQ) may be used as needed.

[ We claim:] [1.] A pyrotechnic method of generating an essentially particulate-free, non-toxic, odorless and colorless gas comprising the steps:a) providing a gas generator having an enclosed chamber with exit ports,b) disposing within said chamber, a solid eutectic propellant solution comprising gas-generative effective amounts of ammonium nitrate (AN) and at least one of aminoguanidine nitrate (AGN) and guanidine nitrate (GN), and effective stabilizing amounts of polyvinyl alcohol (PVA) and either potassium nitrate (KN) or potassium perchlorate (KP) as the sole source of gas, andc) providing said solid eutectic solution also as the means for igniting the propellant eutectic solution upon detecting that the pressure chamber is being subjected to a sudden deceleration, whereby gas is essentially instantly generated and conducted through the exit ports of said chamber.
