Disposal Pipes and Atmos

[FishDance]

I'm not sure if this works with regular rooms filled with gas, but if you set up a hellburn engine to the point where the rooms nearby are incredibly hot, then travel underneath said rooms with a disposal pipe, you will permanently have burning and potentially toxic gas in your lungs. You can use oxygen tanks, go into space and asphyxiate, or go to a completely safe part of the station, but until you die, you will permanently be treated as though you're breathing burning gas.
