An ignition enhancer and gas heater composition for vehicle occupant restraint systems (commonly known as "airbags") contains a non-azide fuel, an oxidizer and a metal. The ignition enhancer composition provides reliable and consistent ignition of a main propellant composition to produce a sufficient amount of gas to inflate an attached airbag within ten to eighty milliseconds or successfully heat the stored gas in a hybrid system. In a preferred embodiment, the enhancer composition contains 5-aminotetrazole, strontium nitrate, boron nitride, mica or clay and aluminum.
