Recently several hybrid rockets have used Nitrous oxide (N2O) as a propellant. The overall consensus is that N20 is much safer and easier to work with than liquid oxygen. It is more forgiving in terms of the temperatures it is kept and how it operates. Even though N2O is a widely used energetic material, the number of decomposition related accidents are quite limited due to its abnormally slow decomposition kinetics. However, hazards do exist, especially in propulsion systems where large quantities of N2O are stored at room temperature in thin walled vessels. The closely coupled combustion chamber is a significant source for ignition which does not naturally exist in other applications. Explore the safety issues associated with N2O with emphasis on propulsion systems. Review the steps in understanding N20 decomposition hazards in order to safely and properly utilize one of the safest oxidizers being used in rocket propulsion systems.
