Fire Doors: The First Line of Defense

Fire doors are a vital part of a building’s passive fire protection system. When properly installed and maintained, they will help to compartmentalize a building to protect occupants and property from the spread of smoke, flames, and toxic gases, and aid in providing a safe means of egress during a fire. However, something as minor as the installation of a fail-safe electric strike rather than a fail-secure model can render the fire door assembly ineffective, potentially endangering the lives of the building’s occupants. Conducting regular inspections and making the necessary repairs can mitigate the risk and liability of having fire doors that may not function properly in an emergency.

Inspection and Testing

Although a jurisdiction may not be officially enforcing the annual inspection requirements that were introduced in the 2007 edition of NFPA 80 – Standard for Fire Doors and Other Opening Protectives, fire door assemblies are required by code to be in good working order. Inspecting newly installed fire door assemblies (a requirement of the 2013 edition of NFPA 80) ensures the building owner has a code-compliant installation to begin with, or allows any deficiencies to be identified and repaired during the warranty period.

The 2013 edition of NFPA 80 includes thirteen criteria for the inspection and testing of door, shutter, and window assemblies upon completion of their installation, and also upon completion of maintenance work on fire door assemblies. The following criteria are evaluated during a fire door inspection.

  1. Labels are present and legible.
  2. No holes or breaks in door or frame.
  3. Glazing and glass kit / glass beads are intact and securely fastened.
  4. Door, frame, and hardware are in proper working order.
  5. No missing or broken parts.
  6. Door clearances are within allowable limits.
  7. Door closer / spring hinges are operational and door is self-closing.
  8. Coordinator ensures that door leaves close in proper sequence (pairs only).
  9. Door is self-latching in the closed position.
  10. Opening is not equipped with auxiliary hardware items which interfere with operation.
  11. No field modifications have been performed that void the label.
  12. Gasketing and edge seals, where required, are present, continuous, and of the proper type for a fire door.
  13. Signage on door covers less than 5% of door face and is not attached with mechanical fasteners.

As in previous editions of NFPA 80, any deficiencies noted during the inspection process must be repaired “without delay.” Records of these inspections must be retained for at least three years, and the media used must be able to survive for the required retention period.

Common Fire Door Code Violations

There are any number of ways that a fire door could cease to be compliant, from simple lack of maintenance to creative modifications. The Door Security & Safety Foundation, an organization that exists to promote secure and safe openings that enhance life safety, has identified the ten most common deficiencies:

  1. Painted or missing fire door labels
  2. Poor clearance dimensions around the perimeter of the door in the closed position
  3. Kick-down door holders installed on the door
  4. Auxiliary hardware items that interfere with the intended function of the door
  5. Fire doors blocked to stay in the open position
  6. Area surrounding the fire door assembly blocked by furniture, equipment and/or boxes
  7. Broken, defective or missing hardware items (latch bolts and/or strike plates, closer arms, cover plates, etc)
  8. Fire exit hardware installed on doors that are not labeled for use with fire exit hardware
  9. Missing or incorrect fasteners
  10. Bottom flush bolts that do not project a sufficient amount into the strike

Modifications of fire door assemblies in the field can also create problems. Job-site alterations are limited by NFPA 80 to preparations for surface-applied hardware, function holes for mortise locks, holes for labeled viewers, installation of protection plates, and a maximum ¾-inch wood and composite door undercutting.  Holes drilled in the field are limited to 1-inch diameter, with the exception of cylinder holes which can be any size. Additional field modifications would require permission from the listing laboratory.

If holes are left in a fire door assembly when hardware is removed, those holes must be filled with steel fasteners or the same material as the door or frame.  There is also a fire door caulk now available for use in filling small holes in wood doors.  Other modifications should not be made in the field without prior approval, unless the doors will be relabeled by the listing laboratory.

“Qualified” Inspectors

The 2007 edition of NFPA 80 (and all subsequent editions) requires fire door assemblies be inspected each year by someone knowledgeable about the type of assembly being inspected.   The 2013 edition added a requirement for the inspections to be performed by a “qualified person” with this knowledge and understanding. This term was defined as follows:

Qualified Person. A person who, by possession of a recognized degree, certificate, professional standing or skill, and who, by knowledge, training, and experience has demonstrated the ability to deal with the subject matter, the work, or the project.

For anyone who may be considering adding fire door inspection to their list of available services, training programs are available through the Door and Hardware Institute (www.dhi.org) and the Associated Locksmiths of America (www.aloa.org) in partnership with the International Fire Door Inspector Association (www.IFDIA.org). The Intertek Qualified Personnel (IQP) Program (www.intertek.com/iqp/) offers a certification for fire door assembly inspectors who have successfully completed the DHI program.

Conclusion

One of the greatest challenges has been the delay in adoption and enforcement of the inspection requirements, although increased awareness is now evident and many fire door inspectors are helping to educate building owners and code officials about the requirements. There is no code-related restriction on having the same person or company conduct the inspection and then make the needed repairs, although some facilities may prefer to keep these functions separate. Another concern is whether additional liability is incurred when doing an inspection. That question is best answered by an insurance professional.

The bottom line is that fire doors must be kept in code-compliant condition, regardless of whether inspection requirements are being enforced. It’s in the best interest of locksmiths who perform commercial and institutional work to understand the requirements for these doors and advise their customers what needs to be done to repair deficiencies so they will function as designed in the event of a fire.

    I have a occupancy separation with a fire rating of 2 hours in Healthcare Facility. What code reference in NFPA 80 is there for the size limitations of the glazing/vision glass I can use in the door? Building is fully sprinklered.

    Thanks
    Joe

      Hi Joe –

      There are a lot of variables here. The first thing you’d have to figure out is what the rating of the door needs to be, and for that you’d need to know which code is in use as well as what type of wall it is. Most 2-hour walls require 1 1/2-hour opening protectives. NFPA 80 doesn’t state how much glass you can use in a 1 1/2-hour door…it says “limited to maximum area tested.” The allowable amount of glazing will depend on what glazing material you’re using, and the listings of the door manufacturer.

      I would start by deciding how much glazing you want, and then checking with your preferred door manufacturer to see whether their listings allow it and what type of glazing is needed.

    Hey,

    This might seem like a very basic question. I am dealing with Fire Door codes for the very first time and am finding it difficult to navigate code. I am supposed to specify the Fire Rating on doors in a mid rise building. All I have in the office is NFPA 101(Life Safety Code) Book. I know that the relevant material will be in NFPA 80, but neither does the office have it and the version that the website offers(free viewing) isn’t complete. How do I specify and find where the relevant code is?

    A quick answer will be greatly appreciated since my deadline is in a couple of hours.
