media should be used depending on thecombustible material involved.Nitrous oxide vigorously accelerates combustion.Materials that would not normally burn in air could combust vigorously in atmospheres having high concentrations of nitrous oxide.If possible, shut off the source of escaping Nitrous oxide. ...
Nitrous acid rapidly decomposes into nitrogen oxide, nitric oxide and water when in solution: 2HNO2 ? NO2 + NO+H2O It can also decompose into nitric acid and nitrous oxide and water. 4HNO2 ? 2HNO3 +N2O +H2O Nitric acid (HNO3), also known as “aqua fortis” and “spirit of nitre”...
