Decoded: Corridor Doors in Health Care Occupancies
Past fires in hospitals and nursing homes - and the resulting fatalities - have shaped the codes that we use today. Although today’s codes do not typically require patient room doors to be fire door assemblies, these doors provide a critical layer of protection for patients.
Elevator Lobby Egress
Fair warning...this is going to be one of those posts that makes your eyes glaze over, especially if you haven't had your coffee yet. But since I've seen several people come to my site looking for this information and leaving without it, I need to post about it before the next person comes looking. I'll try to make it as concise as possible, and remember, the red italicized paragraphs are the code excerpts so you probably don't need to read those unless you're really digging into this issue.
Decoded: Two Releasing Motions for Egress
My next Decoded article covers the tentative interim amendment - TIA 1436, which revised NFPA 101 in order to allow 2 releasing operations to unlatch existing classroom doors.
Decoded: Safe and Secure Schools
My next Decoded article focuses on safety requirements to consider while addressing school security. And while we're on the subject, Safe and Sound Schools is conducting their 4th survey on the National State of School Safety, and I invite you to participate.
UL 294 Follow-Up – 2021 Update
The access control hardware on your project is up and running (phew!), and then you are asked to provide evidence that every piece of electrified hardware on the job is listed to UL 294... (updated with 2021 code references)
Dormitory Tragedy – Ankara, Turkey
Last week I was contacted by an architect from Istanbul, about a recent fire that occurred in a girls' dormitory there. There were 12 fatalities...
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: Communicating Doors Between Sleeping Rooms
The code requirements for communicating doors between hotel rooms have not changed, but a new question has come up...have you ever seen these requirements applied to shared bathrooms between dorm rooms? WWYD?
Survey Q3: “How can you identify a fire door?”
This is the 3rd post in a series about fire doors and the results of a recent (unscientific) survey.
“Yes, I overspecify panic hardware, but let me tell you why…”
In Mark Kuhn's latest post, he makes a compelling argument for specifying panic hardware in some locations where it is not technically required by code. Do you agree with Mark's reasoning?
CONSTRUCT: Clear, Complete, Concise, and Correct Door Schedules
Architects and specifiers may wonder why hardware consultants need so much detailed information – and why it makes us crazy when changes are made and we don’t know about them. It all starts with the door schedule…here’s why each field matters...
Science Lab Doors
Several questions have come up lately regarding the door and hardware requirements for science labs in schools. When a short article about a chemical fire in a lab storage cabinet came across my desk, I decided to do a little digging. I found that fires in school science labs are not uncommon, in fact, the number of injuries to students has grown - in part because of changing educational requirements which advocate more hands-on science instruction. In the event of a lab fire, building code requirements can help to limit the damage to the lab and prevent the fire and smoke from spreading.
Shorty Panics
When panic hardware is installed, the actuating portion of the panic hardware must "extend at least one-half of the door leaf width." I have been taught since my first days in hardware school, that this means the width of the touchpad or crossbar has to measure at least half the width of the door. But lately I've had a couple of situations where someone interpreted this in a different way...

QQ: Roller Latch vs. Roller Strike
I received a Quick Question last week that has come up before: What is the difference between a roller latch and a roller strike? Are both prohibited on fire door assemblies?
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.
Apply It: Mosque Exits – Answers
Here are the answers to Tuesday's real-world questions about the egress requirements for this mosque in Dubai. Read the other post first if you want to give it a try.
WWYD? Exit-Only Doors
If areas with high-piled combustible storage are required to have fire department access doors with hardware on the exterior to allow access, doesn't it seem like doors to other types of buildings should have the same requirements?
Stairwell Reentry
Most stairwells in commercial and institutional buildings are designed to protect the means of egress using fire-resistant construction and fire door assemblies as opening protectives. When building occupants are within a stair enclosure during a fire...
QQ: Astragal vs. Egress Conflict
I have a 3-hour pair of hollow metal doors that requires an overlapping astragal in order to comply with the manufacturer's listings. Both leafs have vertical rod fire exit hardware. How do I avoid an egress conflict?
Decoded: Change to BHMA Standard for Exit Devices
BHMA is required by ANSI to update and review each of the product standards every 5 years, and an important change was made to ANSI/BHMA A156.3 when it was last revised in 2014. The standard now requires cycle tests for Grade 1 exit devices to include preloading...
Specifying Zombie-Resistant Door Openings (Update)
While ensuring code-compliance, of course!
Specifying Zombie-Resistant Door Openings (Update!)
It's hard to believe that it has been 6 YEARS since I last updated this post on zombie-resistant door openings, and 9 YEARS sine I wrote the original version. With the new model codes coming out soon it's time for another update, and what better day to post it than on Halloween??
Balancing Life Safety and Security in Educational Occupancies
This article - about balancing life safety with school security - is the cover story for the Spring 2022 issue of Life Safety Digest. Feel free to share it with school administrators or others who may need it!
Series on Historic Fires
There have been many fires throughout history that have shaped our current codes, and I recently ran across a series in the Enid (Oklahoma) News which includes several events that impacted the door and hardware industry specifically. As I've said before, I think we can learn a lot from the past...
FF Follow-Up
Last week's Fixed-it Friday photo has raised some questions about the best way to handle an unequal pair...a) Do both leaves of a pair require panic hardware?...
Decoded: Stairwell Reentry
The next article in my Decoded series addresses clarifications to the 2024 model codes related to stairwell reentry. These requirements ensure that building occupants can leave a stairwell if it becomes compromised during a fire.
Stairwell Reentry – Revisited
Something recently caught me by surprise and I feel like I should bring it to light so that anyone who is specifying, supplying, or installing electrified hardware on stairwell doors would be aware of the potential issue...
