What happens if nitrogen gas leaks? When liquid nitrogen is exposed to the air, it can turn into a gas. Oxygen levels can drop when this happens and can lead to headaches, lightheadedness and even the loss of consciousness.
Can nitrogen be detected? As nitrogen is colorless and odorless, the organism can absolutely not detect this gas. Only a nitrogen gas detector (oxygen meter) can accurately measure nitrogen concentrations (or rather oxygen rate in the air).
