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. Suitable oxidizing agents are selected from basic metal carbonates and basic metal nitrates. The fuel and oxidizing agent are selected such that substantially nontoxic gases are produced such as mixtures of water vapor and either carbon dioxide or nitrogen.
