==The Less Well Known Hazards of Gases==
* Any gas at pressure over 1000 kPa will cause you to start suffocating as in a vacuum. You can just use internals, though.
* N2O is invisible at low pressures. If you start giggling, put on your internals to avoid passing out.
* Any gas can displace O2, and less than ''16'' (also useful for optimizing internals) kPa of oxygen starts the Oxyloss. CO2 can be removed with the scrubbers, but to get rid of N2 simply apply some way of removing gas from the air and adding O2. My personal favorite is 2 air pumps, 3 connectors and an Air Filter and a canister: 1 pump draws in, goes through the connection and filters N2 into the canister, and the rest to the other pump, which expels it. Can also be used for N2O which is only sluggishly scrubbed otherwise.
* Pressures above 750 kPa do 10 DPS + 5 DPS for every extra 375 kPa above that mark, rounded off. Space suits completely block it all, but there is no other defense.
