Nitrogen is colorless, odorless and tasteless. It is nonflammable, will not support combustion and is not life-supporting. The gas is slightly lighter than air and is only slightly soluble in water. When liquid nitrogen is vaporized and then heated it consumes a large amount of heat, making it an ideal coolant.

Nitrogen is not toxic but also not life supporting.

If insufficient oxygen is present, high nitrogen concentrations cause asphyxiation and death.

Liquid nitrogen can cause frost bites or cold burns.

It is used to provide an inert atmosphere for metallurgical process.

It is used for synthesis of chemicals

It is used for packaging of materials which are sensitive to oxygen

It is used for filling of electric lamps

It is used as a carrier gas in analytical instruments

It is used in laser cutting, shrink fitting or cold fittings of metal parts

It is used for purging or cleaning

It is used for vehicle tyre filling
