Some seals on rated openings, are they required? I know say a rated door with a S in a square but not smoke seal . The inspector fail that opening or a rating door frame label that has UL63, UL 10B and no smoke seal opening was FAILED. This hospital is 30+ years old and ive been here for 5 and this has never been brought to my attention. Are theses true facts? Can anyone point this in NFPA 101?
