The captain ordered the hold to be sealed and pressurised steam was pumped in. In addition nitrous oxide gas in elevated concentrations can cause health effects in operators which should be prevented. In a fire, all types of ammonium nitrate may melt and decompose with the release of toxic fumes (mainly oxides of nitrogen) which may be yellow or brown. Ammonium Nitrate as an Eco–Friendly Oxidizer for Composite Solid Propellants: Promises and Challenges. Jalpa A. Vara, Pragnesh N. Dave, Shalini Chaturvedi. (Redirected from List of Ammonium nitrate disasters) When heated, ammonium nitrate decomposes non-explosively into gases of oxygen, nitrogen, and water vapor; however, it can be induced to decompose explosively by detonation into nitrous oxide and water vapor. The Altmetric Attention Score is a quantitative measure of the attention that a research article has received online. Thermal decomposition of ammonium nitrate is complex and can follow different routes. From a safety viewpoint, it is considered relatively stable at ambient temperature and pressure.

This information is available free of charge via the Internet at http://pubs.acs.org. The heterogeneous decomposition rate of HNO3, HNO3 + (B2O3/SiO2) → OH + NO2 + (B2O3/SiO2), was determined by varying its rate to match the modeled result to the measured concentrations of NH3 and H2O; the rate could be represented by k2b = 7.91 × 107 exp(−12 600/T) s−1, which appears to be consistent with those reported by Johnston and co-workers (Johnston, H. S.; Foering, L.; Tao, Y.-S.; Messerly, G. H. J. Conf.1997, 34-1, 1−5) and ADN decomposition reactions (Park, J.; Chakraborty, D.; Lin, M. C. Proc.
