===[[File:Air_Canister.png]]Air===
A 1:4 gasmix of O2 and N2 (20% O2, 80% N2). The station is filled with this.

Air in SS13 can be seen, strangely enough, as a 'watered down'-O2, with N2 being the water. Optimal atmospheric pressure for humans is 101.3 kPa. Due to the minimum of 16 kPa of O2, the pressure of 101.3 kPa cannot be changed too much without the situation becoming excessively lethal. Under 16 % oxygen? You start dying. Under 90 kPa due to fire from a while ago? You start dying. Be mindful of this.

Air canisters, marked in white, can be found in emergency storages.
