The communicating space is separated from the remainder of the building by fire barriers with not less than a 1-hour fire resistance rating, unless one of the following is met: The entire floor area of the communicating space is open and unobstructed, such that a fire in any part of the space will be readily obvious to the occupants of the space prior to the time it becomes an occupant hazard. The lowest or next-to-lowest story within the communicating space is a street floor. The communicating space does not connect more than three contiguous stories.
Unless prohibited by Chapters 11 through 43, unenclosed floor openings forming a communicating space between floor levels shall be permitted, provided that the following conditions are met:

Ok if you look at A.8.15.4.1 appears if the building code requires enclosure protection, and not there then 8.15.4.1įrom 101:: I am not sure if there is similar language in the IBCĨ.6.6 Communicating Space. In cases where a portion of a floor area is "Open to Above" to an adjacent floor but the opening is not used for a moving stairway or staircase and is not a "Large Opening", are closely spaced sprinklers and draft curtains required? RE: NFPA 13, 8.15.4 - Vertical Openings cdafd (Specifier/Regulator) 23 Apr 13 17:13 It goes on to say "Escalator openings in department stores are examples of vertical openings that would not be considered a convenience opening or convenience space, and as a result they would be required by NFPA 101 to be enclosed to protect against vertical fire spread." These spaces are not required to have a barrier around the opening perimeter (See Section 8.6, Vertical Openings, in NFPA 101 for more details)". In the NFPA 13 (2010) Handbook it states "closely spaced sprinklers are required around a vertical opening only when it would otherwise be required to be protected by a barrier by the building code or NFPA 101.Smaller vertical openings may be referred to in the local building code or NFPA 101 as communicating spaces or convenience openings. NFPA 13 seems unclear whether closely spaced sprinklers and draft curtains are required in these cases. greater than 20' dimensions and area greater than 1000 square feet).
