As suggested by the weakness of the N–O bond, NO 2 is a good oxidizer. Consequently, it will combust, sometimes explosively, with many compounds, such as hydrocarbons.Inhalation of nitrogen dioxide on the lung tissue has a strong irritant and corrosive

Strictly airtight, to provide adequate local exhaust ventilation and comprehensive. Operator must undergo special training, strictly comply with the operating procedures. Recommended operator wear self - absorption filter gas mask (half mask), wear chemical safety glasses, penetrate the gas - gas protective clothing, wear - proof gloves. Away from the fire, heat, smoking is strictly prohibited in the workplace. Keep away from flammable and combustible materials. 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
