Remember...“Not any room can be used as a smoking lounge.
Accommodating smokers in the building may be accomplished by constructing a specifically designed smoking lounge.
The smoking lounge should have direct exhaust to the outside at 60 cfm per smoker (at maximum capacity). Transfer air from surrounding areas may be used for make-up air.
The lounge should be maintained under negative pressure relative to the surrounding areas.
The return air plenum should be sealed off from the smoking lounge and doors should be kept closed.
