if nitrogen is everywhere, why is it a big deal if there is a nitrogen leak?
In: Chemistry
It depends, we use nitrogen as a shield gas in plastic welding. It leaks out in a continuous stream to keep the oxygen in the air out of the weld. Nitrogen leaks in a confined are can be bad, as others have stated, because you can breathe nitrogen without side effects and without oxygen mixed into it you can die.
Adding the scenario where you are worried about a nitrogen leak would make a more specific question that might get better answers.
