Nitrous oxide, a highly reactive gaseous substance with characteristic sweetness, is found in many occupations, including acetylene blow pipe welding, electroplating, metal cleaning and mining, as well as in the manufacture of dyes, Paint or nitric acid in the process may be exposed to nitrogen oxides. Contact with 150mg / m3 nitrogen dioxide 3 ~ 24h, the respiratory symptoms, such as cough, fever, shortness of breath, sputum with bloodshot, extremely weak, nausea and headache

Nitrogen dioxide is gaseous substance a brownish red, highly active, also known as hydrogen peroxide.

Nitrogen dioxide plays an important role in the formation of ozone in the process. Nitrogen dioxide artificially generated mainly from the combustion process of the release, such as vehicle exhaust, boiler emissions etc.. One of the causes of acid rain or nitrogen dioxide.

To prevent leakage of gas into the air in the workplace. Avoid contact with halogen. When handling light light unloading, prevent the cylinder and accessories damaged. Fire fighting equipment and leakage emergency treatment equipment equipped with corresponding variety and quantity.

Store in a cool, ventilated warehouse. Away from the fire, heat source. The temperature should not exceed 30 DEG C. Should be separated from the easy (but) fuel, halogen, food chemicals storage, avoid by all means. The storage area should be equipped with emergency treatment equipment.


Used as an oxidizing agent in chemical reaction and rocket fuel, used as a catalyst in the production of sulfuric acid in nitroso process.

NO2 is used as an intermediate in the manufacturing of nitric acid, as a nitrating agent in manufacturing of chemical explosives, as a polymerization inhibitor for acrylates, and as a flour bleaching agent.

It is also used as an oxidizer in rocket fuel, for example in red fuming nitric acid; it was used in the Titan rockets, to launch Project Gemini, in the maneuvering thrusters of the Space Shuttle, and in unmanned space probes sent to various planets
