http://en.wikipedia.org/wiki/Nitrogen_asphyxiation#Awareness_of_impending_death
>When a human breathes in pure nitrogen, they exhale carbon dioxide without resupplying oxygen. Nitrogen is a colorless, odorless and tasteless gas that comprises approximately 78 percent of the Earth's atmosphere. As such, the subject would detect no abnormal sensation. This leads to asphyxiation without the painful and traumatic feeling of suffocation.
Nitrogen poisoning is hardcore shit. It's heavier than air, so it builds up from the ground if there's a leak. You'll have no clue what's going on until you suddenly get dizzy and pass out, falling to the floor and immersing yourself in a sea of pure nitrogen gas. Death is almost certain unless you are removed from the floor in mere seconds. Often multiple people will die from the same leak, as a second person goes to help the first and instantly collapses and dies before he knows what's happened.
