Smoke Seals on Healthcare non-rated corridor doors???

Sprinklered building, I-2 Use group, 2006 IBC

Section 407.3.1 clearly defines the requirements for corridor doors in healthcare. It says "...shall provide an effective barrier to limit the transfer of smoke..."

Section 710.5.2 says "where required elsewhere in this code.....doors shall be tested in accordance with UL 1784 w/ artificial bottom seal...."

The only place in the code that I see another relative reference to the requirement for UL 1784 is 715.4.3 and 715.4.3.1 which only applies to RATED corridor doors (20 min or greater) and smoke barriers.


1. Do you consider the statement in 407.3.1 listed above to be sufficient direction to lead you to section 710.5.2 thus requiring smoke seals and UL 1784 compliance for doors in smoke partitions.

Thanks for your response and I totally agree. Well maybe not about the screen door…that is pushing it a little.

We have not been placing "smoke seals" on corridor doors in I-2 (sprinklered). It just seems like the hardware consultants’ that we use want to do it.
Smoke seals are highly recommended as doors do not maintain their first installed alignment for fit in the frame and tightness to jamb stops. Considering you are working on a healthcare type building, the smoke seals will be a negligible cost compared to the overall project cost.

As a small tangent off of this ...

Would you advocate a sill seal as well as the jamb and head seals? I've always seen the jamb and head, but rarely the sill seals. It would appear that the sill seal would be the last indication that there's a smoke issue, but ...?
I would recommend the sill seal for critical use areas like intensive care units and operating rooms where evacuating a patient is very difficult and time consuming. Additionally I would recommend a smoke sensor on the "hall" side with a monitor indicator such as a light on the "room" side.

All of this situation needs to also be integrated into the facilities emergency ops plans for various situations such as fire, power loss, violent storms, etc. People need training based on the actual building features such as a smoke sealed door and/or monitor system so they can have good information on their situation and take the most appropriate effective action.
