A novel auto-ignition/gas generating composition contains a primary fuel selected from salts of azoles, alkyl tetrazoles, and mixtures thereof; a secondary fuel selected from salts of organic acids; and a primary oxidizer selected from metal nitrates. A tertiary fuel may also be provided and is selected from organic acids. Gas generators and gas generating systems incorporating the novel compositions are also contemplated.
