During various stages of handling, manufacturing, packaging of chemicals require Nitrogen for various uses. Nitrogen is used to displace oxygen and prevent explosions in highly dangerous atmospheres, such as chemical plants and manufacturing facilities.

Almost every major drug class contains some nitrogen, even antibiotics. Nitrogen, in the form of nitrous oxide, is also used as an anesthetic.

Nitrogen is used to displace oxygen in food packaging. By eliminating the oxygen, the food can last longer. It can also add a cushion around the food to keep it safe from breaking in transport.

Nitrogen is an ideal gas choice for repressurizing depleted oil wells. Along with the benefit of increased productivity, inert nitrogen has no corrosive effect on borehole piping

In the mining industry, nitrogen gas is used to quickly extinguish fires by eliminating the oxygen from the air. And when an area is going to be abandoned, they use nitrogen to ensure the area will not explode.

When electronics are being assembled, nitrogen gas is used for soldering. Using nitrogen reduces the surface tension to provide a cleaner breakaway from the solder site.
