Power and comfort.

I was trying to build some gas scrubbers as a contingency for fires when I noticed that even if they are stopped they still produce the same comfort penalty. Then I noticed that it is true for everything.
Is this as intended? I was assuming that it was a noise thing and that non-functioning noisy things would not produce the same amount of discomfort.

Kitchen fires, right? I once had a Clumsy prisoner that started a kitchen fire immediately after the first got put out. Had I thought of it, I would have executed her. No shortage of pirates.

I want Oxygen Generators in the living quarters, too. I have noticed that the Scrubbers pull the smoke in around them, so it would be best to put them in an adjoining room.
