A sodium-azide-free gas-generating composition includes an oxidizable inorganic fuel, such as a metal, and an oxidizing agent containing oxygen and a metal. The fuel and the oxidizing agent are selected such that water vapor is produced upon reaction between the inorganic fuel and the oxidizing agent. Although a number of inorganic fuels can be employed, a suitable fuel can be a transition metal, another element such as silicon, boron, aluminum, magnesium, an intermetallic compound, hydrides of these metals and mixtures thereof. The oxidizing agent comprises a metal hydroxide, a metal hydrous oxide, a metal oxide hydrate, a metal oxide hydroxide, or mixtures thereof. The fuel and oxidizing agent are selected such that essentially no gases other than water vapor are produced.
