Is Nitrogen Dangerous?

Nitrogen is dangerous to consume in its liquid form. While the chemical is non-toxic, its extreme cold temperature, which ranges as low as -346 degrees Fahrenheit, has the ability to cause significant injury or death.

Liquid nitrogen is used in many commercial endeavors, from making ice cream to chilling cocktail glasses and cooling refrigerators. When used in these ways, the chemical vaporizes into a gas that is harmless. While liquid nitrogen is dangerous if consumed, nitrogen gas is not. Nitrogen gas makes up more than 78 percent of the air humans breathe, and compounds that include nitrogen are necessary for some plants.
