Objective The extinction equipment against hydrazine propellant was studied in order to improve capability of the emergency response to the leakage accident of liquid propellants during the phase of aerospace launching test. Methods The extinction equipment was developed on the basis of advanced liquid/gas double phase current compressed air foam technique.The major structure was composed of the compressed air dynamic system,the double phase current spray gun,the foam pre-mix pot,and the stainless steel cart. Results Compared with the frequently-used extinction measures,this extinction equipment against hydrazine propellant had a wide range and coverage,and produced better-distributed foam. It had higher water saving efficiency and higher extinction effect. Conclusion The extinction equipment against hydrazine propellant,which was convenient,flexible and highly-efficient was proved effective in handling an emergent response to the leakage of hydrazine propellant.
