If the fans are on in here, it's probably safe for us to keep the oxygen mask.
Just a couple of suggestions;-
* Take one of the chairs and use it to wedge the door open. If she wakes up, or someone else goes in, they'll move it, and we won't be dealing with anymore blind door ambushes.
* The fuses were blown in the comms room, however we could still see. So that means we can steal the lighting fuse from this room without major issues.
