Large quantities of hazardous cryogenic propellants are loaded aboard the Space Shuttle prior to launch. The Hazardous Gas Detection System (HGDS) is designed to detect leaks which could result in pre-launch or in-flight fires or explosions. This paper describes the historical development, design and performance of the HGDS. Data for response time, detection limits, accuracy and drift are presented. Finally, present and future applications are discussed and some general conclusions are drawn.
