    Fire Door Requirements By Occupancy

    Can someone point to the codes about where fire doors are required by occupancy? I am familiar with NFPA 80 but am unable to find information about where fire doors need to be installed, assuming there are different requirements for varying occupancies. I am familiar with TABLE 716.1(2)OPENING...

    opaque portion of a door -temperature rise

    When addressing temperature rise for fire doors, the temperature rise limit applies to the "opaque portion" of the door. My questions: 1. Is a fire door in a fire wall allowed to have glazing? 2. Is there a temperature rise restriction on the glazing portion of a fire door in a fire wall?

    Fire Door Signage

    For all of the AHJs out there...I would like to know if you would approve signage on fire doors that meets the 2022 edition of NFPA 80, in jurisdictions where that edition has not yet been adopted. In a nutshell, the new standard allows slightly larger metal signs than the past editions, and...

    Fire rated entry door: 1-2 Family Residential (existing)

    I am a code inspector in upstate New York and I’ve been trying to get a definitive answer on entry doors in a 1 and/or 2 family needing to be fire rated (20 min)? When I started 14 years ago I was trained by my supervisor to enforce that. At this point in my career I like to make sure...

    Fire Door Latching - During/After the Fire

    Sorry - 2 questions in one day that I need help with. I recently received a question about why doors with fire exit hardware don't open during the hose-stream portion of a fire test (or when hit by a hose stream in an actual fire). The reason is because the latching hardware basically fuses in...

    How do you measure bottom clearance on a fire door?

    I could really use some AHJ advice on the question I just posted on iDigHardware. In short, a fire door must have no more than 3/4-inch clearance at the bottom. How is this measured if the clearance is different on the push side and the pull side of the door because of the flooring condition...

    fire rated doors flush bolts top and bottom?

    1 hour rated pair of doors with panic hardware. Are the flush bolts required to be BOTH top and bottom? Can we provide top bolt only? We are in a healthcare setting and are trying to avoid a receiver in the floor that can be a collector of dirt/dust. Thank you in advance for anyone's thoughts.

    Fire Doors Where Not Needed

    I've got another one I'd love some input on. This is part of a larger situation going on with inspections of healthcare facilities, but while I'm waiting for a resolution on that, I'm trying to break down the problem into smaller questions. The questions are...Is it permissible to have a...
