Do fire and smoke rated doors require smoke gasketing in healthcare occupancies which are classified as Group I-2 under the International Building Code® (IBC)?
Ask The Code Weenie!
While NFPA 80 nor NFPA 105 specifically state fire doors and smoke doors require smoke gasketing, the key is to check the applicable code or standard, (i.e., International Building Code), for a limitation on air infiltration, typically a reference to UL 1784, Air Leakage Tests of Door Assemblies, as the test standard, and this would only be required on doors contained within a smoke barrier not part of a cross-corridor assembly. For fire doors and smoke doors in certain locations, the limit for air infiltration is 3 cfm per square foot or less as tested at a pressure of 0.10 inch of water (0.02 m3/(s · m2) or less as tested at a pressure of 0.02 kPa)—for most door sizes, this cannot be achieved without smoke gasketing. The requirements for smoke doors and fire doors depend on where they are used. As such, IBC only requires fire rated smoke barrier doors to meet UL 1784. This results in the effect that life safety surveys involving the use of NFPA 101, 2012 cannot technically mandate the installation of smoke gasketing either for existing or new construction involving smoke barrier doors.
The same would not hold true for fire prevention inspections conducted under the International Fire Codeâ for facilities constructed to meet either the IBC or the legacy Uniform Building Code (UBC) – previously adopted throughout Western Pacific regions of the US. What strategy should facility managers take about existing fire doors where edge sealing is not equipped on fire doors in their facility? Like so many things in code compliance, the answer depends on the specifics of your individual facility. If you need any assistance in understanding this parameter for your facility, AEGIS has fire protection specialists here to help you with code consulting services and inspection services that can help maintain compliance with fire door strategies. What about smoke barrier doors – do the codes say I need to install gasketing on these doors? This question will be answered in our next article of this series.
