Reader Photos
I'm in the mood to clean house (figuratively speaking only), so here's the latest collection of reader photos to hit my inbox. Thank you to everyone who has taken the time to send them. More, please. :-)
Cocoanut Grove & Our Lady of the Angels
When I teach a code class, I often begin by talking about some of the tragic fires that have shaped today's codes. Because of the lessons learned from these fires and the code changes that resulted, the safety of building occupants has been greatly improved.
Movie Night
A couple of weeks ago someone asked me whether the exterior exit doors for a movie theater required panic hardware, and in my opinion, the answer is a resounding YES! Movie theaters are considered assembly occupancies, and the occupant load is well over the limit (50 or 100 occupants depending on the code) that would require panic hardware.
NFPA 80 & NFPA 105
Next Tuesday is the proposal closing date for the 2013 editions of NFPA 80 - Standard for Fire Doors and Other Opening Protectives, and NFPA 105 - Standard for the Installation of Smoke Door Assemblies and Other Opening Protectives.
Labels for Fire-Rated Frames
Questions about frame labels have come up several times this week, so I guess it's time for a post. I've pulled together some information from various sources and I hope some of you will chime in with your input.

I have received SO MANY reader photos lately - THANK YOU!
2009 IBC / 8th Edition Mass Code
If you missed the New England Chapter DHI meeting last week...a Q&A presentation on codes, the question/answer document and the handout are now available on the chapter website.
Good News / Bad News
First the good news. When the annual DHI conference was held in Boston, I conducted a 3-hour code class for architects (I later conducted the class for our DHI chapter.). Public speaking isn't my favorite thing to do, so when one of the attendees approached me before class started and said, "You're not REALLY going to talk for 3 HOURS about CODES, are you?", I got a little nervous. When we conduct presentations for architects, they're typically lunch-n-learns - 1 hour max, with lunch (and cookies!) as an incentive to attend. We get great feedback on our lunch presentations, but asking architects to sit through 3 hours of discussion on hardware and codes was a different story. To my surprise, about 100 architects registered to attend, they actually showed up, and they stayed until the end. I didn't lose my train of thought, pass out, have an "accident", or lose my voice, so I considered the class a success.
Coat Hooks
A couple of weeks ago, someone called to ask me where in the codes it states that 12 coat hooks can not be mounted on a 90-minute rated wood door. I have to admit, that was a new one.
Back to School
I received these photos last week and I didn't have much advice...maybe someone else does. These are classroom doors in a school for autistic children, and the extra locksets are due to the special needs of the students. The students are unable to retract both latches at the same time (if they can even reach the upper lockset). While this keeps the children in the classroom (a good thing), it also prevents egress (a bad thing).
Mouse Holes
These doors are from the same children's museum as the planetarium exit doors in the previous post. I first noticed the "mouse hole" at the bottom of one pair, and wondered why it was there, until I saw multiple other holes with wires running through.
Reader Photos
Maybe I should have a new series called "Jeff Tock's Photos." :-) Jeff is one of the Ingersoll Rand trainers who travels the world teaching people about hardware, and he sees a lot of "special applications." Jeff sent me this group of photos recently (thanks Jeff!):
FDAI Specification – Revised
A while back, I posted some recommended specification language regarding the annual inspection of fire and egress door assemblies, and I have since revised it based on everyone's comments. The original language and comments are still here, and the updated language is below. This should be inserted into the hardware specification for projects designed to comply with the 2009 edition of the IBC, or in jurisdictions which require compliance with NFPA 80-2007 or 2010. Feel free to comment if you have suggestions for improvements.

Some creative and unusual hardware applications sent in by blog readers:
Smoke – NFPA 80
NFPA 80 - Standard for Fire Doors and Other Opening Protectives, is a document which most of us in the hardware industry began studying in our earliest hardware school courses and refer back to throughout our careers. This standard is THE publication on fire doors, and is referenced by all of the codes and standards used in the U.S. that have anything to say about fire doors. You'd think that because of the close relationship between fire doors and smoke doors (some fire doors ARE smoke doors, after all) that NFPA 80 would have something to say about smoke. As it turns out, not much.
Smoke – NFPA 105
I usually like to start with the quick and easy items on my to-do list, which is why it takes me forever to get to the big stuff. It's a fault, and I recognize that, but nobody's perfect. I tried to find the easy place to start this series of posts, but there seems to be only one logical place to begin - NFPA 105.
Smoke – The Series
It’s official. I can’t hide from it any longer. People ask me about “smoke doors” almost every day, but if you know me you know that I have a lot going on, so whenever I try to scale the mountain of information about this topic I get sidetracked by the little things that need my attention.
Don’t Get Burned
On Thursday, May 13th, the New England Chapter of the Door & Hardware Institute will be holding our meeting at a new location - Vinny T's in Dedham, Massachusetts. The meeting topic is fire door assembly inspection (FDAI), and many of the local fire door inspectors will be participating in the presentations. The format is "cracker-barrel" style, where there are 5 or 6 short (10-minute) presentations about various sub-topics, with time for Q&A.
Rosepark Care Home
A while back, I wrote a post about the requirement for fire doors to be self-closing, and I referenced a fire at the Rosepark Care Home in Uddington, Scotland. The fire occurred in 2004, but the results of the investigation are being reported now. I've been collecting news articles related to fire and egress doors on www.firedoorguide.com, and there are several articles there about the Rosepark fire.
Boston Back Bay Fire
There was a 9-alarm fire last week in Boston, in a 10-story condominium building. Several residents had to be rescued by firefighters, because they didn't evacuate the building immediately when the alarm sounded. One resident, who waited 10-15 minutes (by her estimate) to leave, found a stairwell full of smoke and a locked door to the roof. She was found at the roof door in full cardiac arrest with no pulse and no respirations. She was revived by firefighters and she survived. She's extremely lucky.
Stairwell Doors
I think I've seen so many non-code-compliant doors that I'm becoming numb to them. In the old days I would be spurred into action by the sight of a blocked exit or propped-open fire door. Yesterday I was at the local bagel joint and I saw their marked emergency exit blocked with stored high-chairs. No surprise. I went to my chiropractor's office and in the 3-story stairwell, two doors were propped open by the construction crew doing a 2nd-floor office fit-up, and the third floor door's latchset had been removed and replaced with a push plate and pull. Ho-hum.
Triangle Factory Fire – 99 Years Ago Today
The fire at the Triangle Shirtwaist Factory in New York City on March 25th, 1911, claimed 146 lives - mostly young immigrant women. Building owners locked the exit doors to keep the workers in and the union organizers out, so when a fire broke out on the 8th floor it was impossible for some of the 600+ workers on the 8th, 9th, and 10th floors to escape. The fire escape was not sufficient to hold the number of fleeing occupants, and collapsed. Firefighters' ladders were several stories too short, and water from the fire hoses could not reach the upper floors of the building. Sixty workers jumped to their deaths.
Parkside West Fire
Last Tuesday night, approximately fifty people were left homeless by a fire at the Parkside West Apartments in New London, Connecticut, which apparently began on a stove in a 3rd-story apartment. One of the newspaper accounts of the fire investigation reported that the fire marshal stated "in the third-floor apartment where the fire is believed to have started, a weatherstrip prevented the door from closing, allowing smoke to spread."
Full Surface Hinge
I've been writing a lot about fire doors lately, and specifically about what bad condition many existing fire doors are in. The codes have always required fire doors to be kept in good working order, but with the specific requirement for the annual inspection of fire doors it will hopefully bring more of these deficiencies to light.

Survey Q4: “What are some ‘rules’ regarding fire doors?”
Back to business after a brief vacation in Costa Rica...
Costa Rican Egress / Fire Protection
The hotel with the treacherous handicap ramp (see previous post) was actually a very nice little hotel, but it had some other code-related issues. I think all of the issues stem from the lack of stringent building codes in Costa Rica, but they're still a little scary for travelers who happen to be door hardware consultants.
Survey Q4: “What are some ‘rules’ regarding fire doors?”
This is the 4th post in a series about fire doors and the results of a recent (unscientific) survey.
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.
Survey Q2: “What is the purpose of a fire door?”
This is the 2nd post in a series about fire doors and the results of a recent survey.
Survey SAYS…
A couple of weeks ago I posted a survey to find out what people know about fire doors. The purpose was to test my theory that the reason fire doors are improperly modified and damaged hardware is left unrepaired is because people don't realize a) which doors are fire doors or b) what can or can't be done to a fire door. I originally developed this theory while I was creating a presentation about fire door inspection, and I wanted to have data to support it.
Construction Label
Last week I was on a conference call for one of my projects in Washington DC, because of a problem with the specified concealed closer and the fire-rated wood door and wood frame. The door manufacturer suggested a "construction label," and most of the call participants needed an explanation of what that was. I thought posting a description here might help others who are wandering the web seeking information about construction labels. (Don't laugh...you wouldn't believe how many people come to this site wondering what a Cush arm is.)
Fire Door Survey
In 2007, the annual inspection of fire door assemblies became a code requirement that is gradually being adopted across the U.S. Given the enormous quantity of fire doors and the relatively small number of qualified fire door inspectors, implementation of this change has been challenging, but because of the appalling condition of the fire doors I see daily, I am determined to increase awareness of this requirement and use it to improve the safety of buildings.
Same Hotel, Different Day
Luckily, we are safely home and the hotel didn't catch on fire, but I did take a quick tour of the place before we left. Almost none of the fire doors that I looked at were code-compliant, and I wasn't being nitpicky.
NFPA 80 – 2010
I recently received my copy of the 2010 edition of NFPA 80 - Standard for Fire Doors & Other Opening Protectives, and I spent some time today perusing the changes (indicated by a vertical line to the left of the revised text).
History Repeats Itself, Again
Once again, failure to follow fire safety and egress code requirements in a nightclub has resulted in a fire with multiple fatalities. The death toll from the December 4th fire at the Lame Horse in Perm, Russia currently stands at 112 with more than 100 people severely injured.
FDAI in Specifications
UPDATE: I wanted to preserve this original post but the recommended specification section on fire and egress door assembly inspections has been updated and is available HERE.

Hospital & Nursing Home (I-2) Cross-Corridor Pairs
The 2009 edition of the International Building Code (IBC) contains an important change that's easy to miss if you're not looking for it. I stumbled across it a few months ago when someone asked me about the exception for cross-corridor doors without positive latching in I-2 occupancies.
Opening Force for Fire Doors, Part 2
In a post about opening force a while back, I wrote that fire doors do not have to meet the opening force requirements of the accessibility codes and standards. While that IS true, someone recently asked me a question that led to this further explanation.
Louvers in Fire-Rated Doors
When I started working in the door and hardware industry, we regularly installed fusible link louvers in fire-rated doors, as allowed by various door manufacturers' listings. Although fusible link louvers are still available, their use is limited by current codes:
NFPA Journal Door Inspection Article
There's an article in the May/June 2009 issue of the NFPA Journal about the inspection of egress doors and fire doors. You can access the article here. It's an excellent overview of the inspection requirements found in the 2009 Edition of NFPA 101 - The Life Safety Code.
Protection Plates in Health Care
There's an exception in the Health Care chapters of NFPA 101 that I've always wondered about. It's in the chapters regarding New & Existing Health Care Occupancies (18 & 19), in the section about corridors:
Exit Enclosure
My last post referenced the term "exit enclosure", and I received a few questions about its meaning. An exit enclosure is the enclosure around an exit. For our purposes it usually refers to a stairwell. According to the IBC, exit enclosures connecting 4 or more stories require a 2-hour fire resistance rating, and those connecting less than 4 stories require a 1-hour fire resistance rating (IBC-2009-1022.1). Exit enclosures must lead directly to the exterior or to an exit passageway, which will typically have the same fire resistance rating as the exit enclosure. The IBC includes some exceptions for exits which do not need to be enclosed, such as stairs in parking garages.
Temperature Rise Doors
A temperature rise door is a fire-rated door which limits the heat transfer through the door for a period of 30 minutes. Temperature rise ratings indicate the maximum rise above ambient temperature on the non-fire side of the door, and will be either 250°, 450°, or 650° F. The 250° door is the most restrictive because it limits the heat transfer to only 250° for a 30-minute period. A typical hollow metal door would reach approximately 1400° F in the same time period. By minimizing the transfer of heat, a temperature rise door could protect an exit enclosure, allowing people to pass below the floor of fire origin.
