A process for manufacturing a gas generating material includes preparing a wet mixture of a metal azide and a metal oxide without prior mixing of the metal azide and metal oxide in dry form. The metal azide content of the gas generating material is controlled and the possibility of forming hazardous hydrazoic acid fumes is minimized by maintaining the temperature of the wet mixture of gas generating material between 20°C. and 30°C. The possibility of forming hydrazoic acid fumes is further reduced by maintaining the pH of the wet mixture of gas generating materials at or above 10.5. Excess liquid is removed from the wet mixture of gas generating materials so that the wet mixture has a moisture content of approximately 9%. The excess liquid from the wet mixture is recycled and used the formation of additional gas generating material. The wet mixture of gas generating materials, having a moisture content of approximately 9%, is formed through small openings to form extrudate of gas generating material.
