I think you would need to be working on an industrial scale for that to be an issue. Plus, that's where they came from in the first place - outside. Ventilation also provides fresh air, otherwise you would have too much CO. Part of any ventilation system should include makeup air coming from a direction other than the one to which you are venting.
