Abstract
The Chemical and Materials Section of the Rocket Research Laboratories at Edwards Air Force Base has been responsible for hazard appraisal of various storable liquid propellants. Evaluating the toxic hazards posed by spills or inadvertant releases was curtailed by a lack of suitable instrumentation and by the shortcomings of applying laboratory wet chemical techniques to field experiments. Under contract to Edwards Air Force Base, Mine Safety Appliances Company developed an instrument suitable for continuous monitoring for toxic levels of NO2, UDMH, B5H9, N2H4, F2 and CIF3. Based on spill test data from Edwards Air Force Base, realistic performance specifications are suggested for any continuous toxic hazard monitoring equipment for missile facilities.
