Code-Compliant Doors: What to Look For

This article was published in the February 2013 issue of the Locksmith Ledger:

I was recently contacted by a locksmith from a local university who attended my class on fire door inspection last year.  A new dormitory on campus is in the final stages of construction, and many of the fire doors have been installed with perimeter clearances that exceed those allowed by NFPA 80 – Standard for Fire Doors and Other Opening Protectives.  The locksmith was concerned that when the local fire marshals eventually begin to enforce the annual fire door assembly inspection requirement, the facility would then be responsible for the non-compliant doors.

Missing LatchThe requirement for fire doors to be inspected annually was added to the 2007 edition of NFPA 80, and carried forward in later editions.  When other codes – particularly fire codes – reference those editions of the standard, annual fire door assembly inspection becomes a requirement for that jurisdiction.  Code officials may not immediately be aware of the requirement because it is in a referenced standard and not the code itself, but eventually the requirement will be enforced.  The change to the standard has brought much-needed attention to the condition of fire doors, and a similar change in NFPA 101 – The Life Safety Code (2009 edition and later) addresses the inspection of certain egress doors.

But responsibility for keeping doors in code-compliant condition does not begin when the annual inspection requirements are enforced.  Fire doors help to compartmentalize the building and are an important part of the passive fire protection system.  Facilities, including the university with the new dorm, are responsible for maintaining those doors in code-compliant condition from Day 1.  This has always been the case…I went back to my 1961 edition of NFPA 80 and found a 12-point Care & Maintenance section, including a mandate for “a continual maintenance and inspection program to insure that doors will operate under fire conditions.”  My advice to the locksmith?  Insist that the fire door issues are corrected before accepting ownership of the new dorm.

Deadbolts on Egress Door Locksmiths have an opportunity – and a responsibility, to inform the facilities they visit about any compliance issues with their fire doors and egress doors.  NFPA 80 and NFPA 101 both require any problems to be corrected “without delay.”  Accessibility issues should also be addressed with the facility.  Here are some issues to watch for:

Operation – Does the door operate properly, open and close without binding?  Is any of the hardware damaged, defective, or missing?  A leaking door closer might still close the door, but it may not control the door properly or comply with accessibility requirements for closing speed – typically 5-6 seconds.

Labels – Fire doors are equipped with a label, and frames for fire-rated openings may have a label or may be embossed with a listing mark.  These labels must be present and legible.  If they cannot be made legible, the Authority Having Jurisdiction (AHJ) may require the openings to be relabeled by a listing agency.

Closing – One of the most common issues with fire doors is a damaged or defective door closer – fire door assemblies must be self-closing or automatic-closing.  Self-closing doors have a closing device (door closer or spring hinges), which closes the door each time it is opened.  Automatic-closing doors have a hold-open device that will release the door and allow it to close during a fire.  Test these devices to ensure that they release and that the doors close properly.  Kick-down door holders and other mechanical hold-open devices are not acceptable for use on fire doors and must be removed.  If fire doors are held open with door wedges or similar means, installation of code-compliant hold-open devices should be considered.

Hotel Door ClearancesLatching – In order to keep the door in a closed position during a fire, most fire doors are required to positively latch by means of an active latch bolt.  If panic hardware is installed on a fire door, it must be fire exit hardware which is listed for both panic and fire protection.  It’s fairly common to see existing fire doors which have had the latching hardware removed – this hardware must be replaced.  Most egress doors are required to unlatch with one operation, so the installation of additional locking devices on egress doors can be a problem.  Many codes exempt residential dwelling unit entry doors from the single-operation requirement.  If latching hardware needs to be replaced, upgrading existing knobs to levers is recommended and may be required.

Clearance – Another very common problem with fire door assemblies is incorrect clearance around the perimeter of the door.  The maximum clearance allowed for wood doors is 1/8” at the head, jambs, and meeting stiles of pairs, with a maximum of 3/16” for hollow metal doors and a maximum of ¾” between the bottom of the door and the top of the flooring or threshold.  A perimeter clearance problem may potentially be solved by shimming the hinges with steel shims, and there are currently products under development to address the clearance issue as well.

Fasteners – Are any fasteners missing from the hardware, or have original fasteners been replaced with an incorrect type?  Listing procedures typically require hardware to be installed with the fasteners furnished by the hardware manufacturer.  Using different fasteners may void the listing.

Holes in Fire DoorHoles – When hardware is replaced, there are often holes left in the door or frame from the mounting screws for the original hardware.  These holes must be filled with steel fasteners, or with the same material as the door or frame.  Any products used to fill holes must be listed for that use, and currently there are limited products available which have been tested for use on fire door assemblies.  Most fillers that have traditionally been used to fill holes in fire doors are not listed for this use.

Glass – For many years, codes have required glass used in doors and sidelites to be impact-resistant, but there was an exception for fire doors because of the lack of glass products which met both the fire resistance and impact resistance requirements. Many existing fire doors are equipped with traditional wire glass, which does not meet the current code requirements for impact resistance.  There are now many glass products, including new wire glass which does meet the impact requirements, and most codes now require impact-resistant glass to be used in fire doors as well as non-rated doors.  This glass will bear a small label or etching which includes codes indicating the properties of the glass.  Given the dangers associated with traditional wire glass in doors, replacement of this glass in existing doors in hazardous locations is recommended but may not be required.  Under current codes, impact-resistant glass is required, even in fire doors.

Modifications – NFPA 80 limits field modifications on fire doors to holes for surface-applied hardware, function holes for mortise locks, and holes for labeled viewers, with a maximum hole size of 1” diameter.  The standard also allows field preparation for protection plates, and wood and composite door undercutting – a maximum of ¾”.  Other field modifications must be approved by the listing agency, which usually involves the door or frame manufacturer as well.

Remember, code-compliance is not dependent on whether the AHJ is enforcing the annual inspection of fire doors and egress doors.  These doors are required to be code-compliant today.  There is more information about many of these topics on

    The importance of using unlisted panic hardware in a location that has fire requirements should be emphasized. In my career I have seen this mistake made dozens of times. In one new building, fire rated hardware was installed on an outside door with no fire exposures. The panic hardware, clearly labeled as such, was installed in a 2 hour fire wall. Not only were the labels very clear but one could see the apparatus for dogging the panic bar down with a hexagonal wrench to unlatch the panic hardware.

    Sometimes the dogging mechanism access is plugged with a small plastic plug, sometimes there is no plug but the hole on the push plate calls attention to the potential of panic hardware installed on a fire rated door. I watch for any sign of a mechanism to restrain the latching such as the dogging access hole and verify the rating by looking at the rating plate. When I have asked various contractors why they installed the wrong sets on the wrong doors, they are invariably uninformed about the difference. Hardware is often installed by the general contractor who does not specialize in installation. My experience indicates that the contracting public has an opportunity for education here.

    I have found that many fire doors that have been worked on do not retain the fire rating as a change of hardware has left many holes in these doors and no one knew that this was wrong. Yes I find that contractors who do installing doors and hardware only cause more work for the locksmiths. A lack of rules regarding fire doors seems to be the norm.

    What is the current test for self latching? For security purposes, I have two “tests” that i run on doors, one of which is allowing the door to close, just until the latchbolt touches the lip of the strike. Hold the door there, then release. If its all is well, the closer should pull the door into the latched position. MANY doors do not pass this test (more don’t then do). So how does a Code official test the door… I mean specifically?

      Sorry for the delay…I knew I had this somewhere!

      we call that ‘latch parking’ and for example, it’s what kids to to a pool gate
      to leave it so that their unauthorized peers can get in… huge liability issue.
      this is why i won’t put other than an ordinary commercial door closer on a pool
      gate and the pool gate has to have the standard door/frame configuration so that
      i can mount a closer on it at the top in a ‘parallel-arm’ configuration. also,
      keeps the closer arm from being out there in a ‘v’ formation allowing for a
      monkey bar nuisance attraction. AND i’ll virtually guarantee that it actually latches
      100 percent of the time. latch parking works well with crap closers like kant-slams…

    Is there a third party in Las Vegas that could help in telling me if our wood doors and frames are fire rated and can be field labeled or not.
