Hypergolic fluids are toxic liquids that react spontaneously and violently when they contact each other. These fluids are used in many different rocket and aircraft systems for propulsion and hydraulic power including, orbiting satellites, manned spacecraft, military aircraft, and deep space probes. Hypergolic fuels include hydrazine (N 2H4) and its derivatives including monomethylhydrazine (MMH), unsymmetrical di-methylhydrazine (UDMH), and Aerozine 50 (A-50), which is an equal mixture of N2H4 and UDMH. The oxidizer used with these fuels is usually nitrogen tetroxide (N2O4), also known as di-nitrogen tetroxide or NTO, and various blends of N2O4 with nitric oxide (NO). Several documented, unintentional hypergolic fluid spills and fires related to the Apollo Program, the Space Shuttle Program, and several other programs from approximately 1968 through the spring of 2009 have been studied for the primary purpose of extracting the lessons learned. Spill sites include KSC, JSC, WSTF, CCAFS, EAFB, McConnell AFB, and VAFB.
