Decoded: Doors Provided for Egress Purposes
If it looks like a door and swings like a door, building occupants (and the code official) will probably think it’s a door, and it should operate like doors are supposed to.
Decoded: Extraneous Labels on Fire Door Assemblies (April 2020)
If a labeled fire door is installed in a location where a fire door is not required, must the assembly be maintained and inspected according to the requirements of NFPA 80?

Remember when I went to Italy in July and I took hundreds of photos of doors and then hardly shared any of them with y'all because some of the photos were going to be published in Door Security + Safety Magazine?
Decoded: Update on Roof Doors (August 2019)
A change to the 2018 edition of the International Building Code (IBC) and the International Fire Code (IFC) helps to establish the intent of these codes with regard to roof doors.
Decoded: Locks Used Only for Security Purposes (July 2019)
The IBC exempts locks used only for security purposes from the mounting height requirement. The accessibility standards exempt locks operated only by security personnel. What's the difference?
Decoded: Thresholds and Gasketing for Fire Doors and Smoke Doors (June 2019)
Thresholds and gasketing are simple in comparison to other types of hardware, but the code requirements can make them difficult to properly specify and supply.
Decoded: Why Barricade Devices? (May 2019)
Why would a school district consider using unregulated security devices, given the associated risk and liability? The answer may surprise you.

Decoded: Manually-Operated Sliding Doors (April 2018)
Manual sliders are not always allowed in a means of egress, since the model codes require side-hinged or pivoted swinging doors for most locations. The International Building Code (IBC) currently contains 9 exceptions where swinging doors are not required.
Decoded: Update on Storm Shelter Doors (March 2018)
If you have seen more projects incorporating storm shelters lately, this is likely due to changes in the International Building Code (IBC).
Decoded: Panic Hardware Requirements for Rooms Housing Electrical Equipment (February 2018)
NFPA 70 – National Electrical Code (NEC) has been adopted by most US states, and includes requirements for panic hardware or fire exit hardware on certain rooms housing electrical equipment; the voltage and amperage thresholds that determine which rooms require panic hardware were changed in the 2017 edition of this code.
Decoded: Locations for Vision Lights and Viewers (January 2018)

Decoded: Fire-Protection-Rated vs. Fire-Resistance-Rated Assemblies (March 2016)
Where can we continue to install fire-protection-rated openings (NFPA 252 or UL10C) and where do we need to install fire-resistance-rated openings (ASTM E119 or UL 263)? One clue can be found in NFPA 80. In the 2013 edition, Paragraph 6.3.3.3 states that transom frames and sidelight frames are permitted when a fire-protection rating of 3/4-hour or less is required...
Decoded: Communicating Doors Between Sleeping Rooms (February 2016)
A door opening between two adjoining hotel rooms is called a communicating door, and is created by installing two doors within one frame - each swinging in the opposite direction. The purpose of these doors is to allow convenience for family or friends sharing two hotel rooms, but the doors also provide security between the two rooms when occupied by separate parties...
Decoded: Smoke Door Requirements of the International Building Code (Updated July 2019)
Several of you have asked me to update the article on smoke doors that I wrote several years ago. I have looked at this until my vision is blurry, so if anyone is willing to review it for errors I'll offer a bounty for any mistakes found...

Decoded: Fire Door Closing Cycle (September 2015)
It has been 8 years since the annual fire door assembly inspection requirements were added to the 2007 edition of NFPA 80 – Standard for Fire Doors and Other Opening Protectives. Six years ago, the 2009 model codes referenced the 2007 edition of NFPA 80, making the inspections required by code in jurisdictions where those codes were adopted...
Decoded: Patient Room Doors in Health Care Occupancies (August 2015)
The recent nursing home fire in central China which killed 38 elderly residents is a deadly reminder of the responsibility of these facilities to keep their residents safe. While the code requirements for health care facilities and nursing homes go far beyond the doors, frames, and hardware, there are some important considerations for door openings...
Decoded: Screen Doors and Doors in a Series (July 2015)
Screen doors are sometimes used in commercial or institutional occupancies, where air transfer through the opening is desired. One example of this would be a door leading from a commercial kitchen to the exterior. In some areas of the country where the climate is temperate, this is a common application which consists of two doors in the same opening, one inswinging and one outswinging. It can be very difficult for people with certain disabilities...
Decoded: Double-Egress Pairs in a Health Care Occupancy (June 2015)
There is an IBC exception regarding smoke barrier doors that has to be one of the most confusing and widely debated door-related sections in the code. In the 2015 edition, Section 709.5 Exception 1 exempts smoke barrier doors in some health care occupancies from the requirements that apply to smoke barriers in other locations...
Barricade Device? Think Twice! (May 2015)
I've edited this article and the downloadable PDF - feel free to share it!...There is a question currently under debate in several jurisdictions across the country – should barricade devices be used to secure classroom doors during an active-shooter incident?
Decoded: Electrified Hardware Refresher (April 2015)
There are 7 basic code categories for electrified hardware used to control access or egress, and this edition of Decoded provides a brief refresher on each as well as some recent code changes. Many of these code applications, but not all, fall into the category commonly called “special locking arrangements.”
Decoded: Egress Terminology (March 2015)
As I mentioned in my previous column, there are other factors that affect the quantity and location of egress doors, beyond the general requirements for 2, 3, or 4 exits depending on the occupant load. For example, doors used for egress need to be located remotely...
Decoded: Calculating the Egress Width of Door Openings (Updated July 2017)
A common question when replacing doors and hardware during a renovation is whether one leaf of a pair can be “fixed” in place, or whether an opening can be eliminated completely. It’s very risky to make this decision without consulting the Authority Having Jurisdiction (AHJ), but it is helpful to understand some of the factors that could affect the location, size, and quantity of required exits before preparing your request for the AHJ...
Decoded: Test Your Knowledge (January 2015)
You may have already noticed...I've been taking a little time off between the holidays, but here's something to keep you busy until I'm back in action next Monday...
6 Accessibility Changes to Watch Out For (November 2014)
The 2010 Americans with Disabilities Act (ADA) Standards for Accessible Design went into effect in March of 2012, but there are several requirements that continue to surprise architects and specifiers as well as door and hardware suppliers. These issues can be costly to resolve if they’re discovered after the doors and hardware are on-site, so it’s important to stay current on the requirements...
Decoded: Fair Housing Act (October 2014)
A common misconception is that the Fair Housing Act applies only to federally-funded housing projects, but according to the US Department of Housing and Urban Development, “The Fair Housing Act requires all ‘covered multifamily dwellings’ designed and constructed for first occupancy after March 13, 1991 to be accessible to and usable by people with disabilities. Covered multifamily dwellings are all dwelling units in buildings containing four or more units with one or more elevators, and all ground floor units in buildings containing four or more units, without an elevator.”
Decoded: Calculating the Occupant Load (September 2014)
Many code requirements are dependent upon the occupant load of the room or space in question. For example, the International Building Code (IBC) requires panic hardware for doors equipped with a lock or latch, which serve Assembly or Educational occupancies with an occupant load of 50 or more (the occupant load limit for NFPA 101 – The Life Safety Code is 100 or more)...
The Effect of Oversized Clearances on Fire Door Tests (August 2014)
Rectifying clearance problems can be difficult and costly, so it may be tempting to leave non-compliant doors in place and assume that a little extra clearance won’t affect the performance of the fire door assembly; I can now say from first-hand experience that this is not true...
Decoded: Use Groups and Occupancy Classifications (July 2014)
In Chapter 3, the IBC defines each “use group” and NFPA 101 - Chapter 6 describes each “classification of occupancy.” Both terms describe how the building or a portion of the building will be used, and each of these codes contain requirements specific to certain uses...
