Negative Air Pressure Rooms Where others are protected from any airborne transmission from a patient who may be an infection risk (Class N). Anterooms Negative air pressure rooms with Anterooms, with interlocked doors, which are used for quarantine isolation (Class Q). Isolation Room Design When designing an isolation room, make sure the anteroom has enough space for storage and application of PPE. The door into the anteroom from the isolation room should be self-closing, and should swing into the anteroom. The anteroom provides access to the isolation room for staff and visitors. For Class N isolation rooms, due to the negative pressure relationship between the isolation room and the surrounding area, separate doors can be provided for the ingress and egress of the patient’s bed directly in and out of the isolation room. It is imperative that the isolation room keeps negative pressure to the anteroom, and the anteroom keeps negative pressure to the surrounding area, to ensure infectious particles do not escape from either room into the surrounding areas when any of the doors are open. Magnehelic gages should be installed to ensure negative pressure relationships are held. A dedicated exhaust system should be provided from the isolation room. To maintain negative pressure, the exhaust system needs to remove more air than what is being supplied into the room. The exhaust air ducts for isolation rooms should be independent from the building’s air exhaust system. This will reduce the risk of contaminated air finding its way back into non-contaminated areas through a back-draught situation. FIND YOUR CLEAN SPACE.
