The stairway with the smoke -proof enclosure should be extended tothe roof surface. The door opening at the roof should be 1 1/2 hour fire protection assembly. she penthouse over the stair enclosure should be a minimum 1 hour noncombustible construction. None of the 3 stairs shown on the plans comply as a smoke -proof enclosure. Section 3309, and 3601(d) *2.
