Assembly Egress
Hopefully you're not getting sick of my vacation photos because I've got a few more. This post has a special bonus at the end though - something I've NEVER seen before.
Iroquois Theater Fire
Today is the 107th anniversary of a tragedy at the Iroquois Theater in Chicago, which shaped the early codes and led to the invention of the panic device. More than 600 people lost their lives in this fire, making it the deadliest theater fire and the deadliest single-building fire in United States history.
Unequal Pairs
I've talked about this before, but the question still comes up almost weekly - "What's the code-compliant solution when replacing a pair of doors in a 5'-wide opening?"
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. :-)
Decoded: NFPA 72 on Access Control (December 2010)

Connections
When I started this blog, my goals were to organize all of the code information I had into a searchable database, and to offer a more painless way to learn about hardware. I think one of the hardest things about starting out in this industry is the way most of us learn about it - at the School of Hard Knocks. There are some great classes available through DHI and other sources, but it can take a very long time to attend them all, which gives us plenty of opportunities to make mistakes. I know I've made my fair share over the years, so I wanted to help people learn a little bit at a time and hopefully make it as painless as possible.
Exit? Really??
I received these photos from a fire inspector in Texas who shall remain nameless so he'll keep sending me the crazy stuff he sees in his travels. If you recall from earlier posts, an egress door has to look like a door, and can't be disguised in any way. This egress door is in a restaurant that seats 200-250, and the second photo is what the means of egress looks like after you go through the door. Nice.
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.
Double Cylinder Deadlocks – Residential
I don't get involved with residential construction very often, but a local locksmith recently asked about the use of double-cylinder deadlocks on single family homes. His position is that he will not install them, but he was looking for a code reference to back him up.
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.
Maverick Bars
I recently received this photo from Michael Wojnarowski of Builders Hardware, and it reminded me of a Powerpoint presentation I ran across a while back. The presentation was created by the Anne Arundel County Fire Marshal Division - Code Enforcement Bureau, and the topic is Maverick Bars.
Out to Lunch
I saw this door at a restaurant today. The decor is meant to look like a garage, and it's pretty cool - I especially liked the naked closers. I did wonder about the main entrance door though. It's tough to tell from the photos, but the graphics from the wall run over the aluminum portions of the door and frame and across the glass, so the glass is tinted orange with the dark stripes running across. You can barely see the word "extra" on the glass at the top of the door, but look at the window on the side of the vestibule - it's the same treatment that's on the door. When I looked at it from my seat it looked dark orange just like the wall.
Stay in School
I just noticed an article in the Edinburgh Evening News that was worth sharing. No, I don't make a habit of reading Scottish newspapers, but thanks to Google I see all kinds of news items involving fire doors.
Courtyard Egress
A few weeks ago I did a post about egress from an occupied roof, and that reminded me to go back and dig out some courtyard photos I took a while ago. When a courtyard is completely enclosed with no means of egress that leads directly to a public way, the path of egress is typically into the building and then out again through the building's egress doors.
Trick or Tweet
Ellen DeGeneres cracks me up - even though she never talks about doors and I never have time to watch her show any more. Recently, Ellen and I became Facebook friends, so I get random status updates from her show which often include videos. I happened upon a video of when she sent one of her writers through a haunted house, and about 25 seconds into the video, I noticed a set of emergency exit doors (which have LCN 4110s and Von Duprin 99s if I'm not mistaken). Yes, I do realize that I'm a weirdo, but you should know that by now.
Reader Photos
Here are some more reader photos that have recently hit my (e)mailbox...
Gates
My daughter Norah and I went to New Haven yesterday for what will hopefully be our last trip to Yale-New Haven Children's Hospital. Thank you to everyone who has inquired about her...she's doing great and is back to her old tricks.
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.
Rooftop Garden
As promised, I found quite a few interesting applications during our stay at Yale-New Haven Children's Hospital, which I will post here in the next few weeks. I also received some reader photos in response to my plea for help in keeping this site supplied with posts that weren't too time-consuming for me while my daughter recovered from her surgery. Thank you for the photos, as well as the emails to check on her progress. We were able to go home on Friday as planned, and she's running around like nothing happened.
Surgical Suite Entry
I have been amazed and touched by the number of people who actually read my Good News/Bad News post all the way to the end and took the time to call or email me about my daughter's surgery. Thank you so much for your care and concern. It has been a tough week and an extremely stressful day, but everything went perfectly and my daughter is doing really well. We're still in the hospital but we hope to be able to go home tomorrow (actually today since it's 2 a.m.).
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.
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).
The Coliseum
You wouldn't think that a fair would be a great place for door-hunting, but I saw the doors below at The Big E last weekend. There's a lot going on here - sliding, folding, and swinging doors serving a giant assembly occupancy. This reminds of many scenarios dreamed up by architects that I've advised strongly against. No offense to all of the architects out there, but I'll bet the facility hates these doors.
What would you do?
I received the comment below on my post about the childrens' museum doors with applied panels painted to look like stone. It's a good question, so I'm turning it into a post of its own.
Faux Stone
To finish up my spontaneous series on the children's museum, here are a few of the faux-painted doors we saw there. I think these are even harder to distinguish as doors (when they're closed) than the planetarium exit.
Planetarium Exit
When I need inspiration for what to write about and nobody has sent me a good code question that day, all I have to do is look back at my photos from family outings. That's sad, I know. :-)
All Fixed!
My site has been moved to a new server so hopefully all of the technical difficulties are behind us and I can get on with the important stuff - DOORS! :-)
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!):
Reader Photos
The good news is that these doors are being replaced, presumably with doors that will provide security without jeopardizing life safety. The bad news is that this is a popular restaurant and their main entrance doesn't come close to meeting the requirements for egress.
LAX Egress
It's not very often that I see a news report about egress doors that don't meet code requirements. Considering the prevalence of the problem, it's amazing to me that it doesn't get more publicity, but then again, I'm a little more focused on the problem than the average citizen.
Notre Dame Cathedral, Paris
Every day I find a new excuse to avoid reading and writing about smoke doors. I swear I'll get back to them, but as construction gets rolling again we're getting really busy.
Sortie D’Urgence. Briser et Presser.
This is a new one. Translation: "Emergency Exit. Break and Press."
FDAI Speed Dating
Tonight I attended the local DHI chapter meeting, where I was one of the presenters in a "cracker barrel" style presentation on fire door assembly inspection. It was kind of like FDAI speed dating. We had 6 tables, each with a different topic and 1 or 2 presenters per table, and the attendees cycled through all of the tables to hear a 10-minute presentation on each topic.
Construction Zone
I know you're probably anxious for me to get back to the smoke series, but it's Mothers' Day so I'm going to take one more day off. Instead I'm posting the photos below, which I took yesterday at the local college campus center. Our school was using their function room for a fundraiser, and this door was the emergency exit for the room. On the other side of the door is a construction zone, and neither door was operable.
Hotel Meeting Rooms
It's a little scary how excited I get when I find photos in my inbox...mostly because it makes the subsequent post pretty easy and I don't have to try to make the doors I see during my own wanderings meaningful. I received these photos from one of our esteemed trainers, who travels around teaching people about hardware. Any hardware people who have attended a class in a hotel meeting room can vouch for the scary hardware applications you can find there.
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.
Stephens Court, Calcutta India
This building in Calcutta was involved in a fatal fire today, with 24 deaths reported so far and additional people still missing. The top floors of the building had been added illegally, but the building owner paid a fine and all was forgiven. The fire department reportedly had never inspected the building.
More Costa Rican Egress
When we drove through Santa Elena, we noticed a restaurant with a tree growing up through the middle of it. It looked pretty cool, so we headed there for lunch after our 3-hour morning hike in the Monteverde Cloud Forest Reserve and before our afternoon hike at the Selvatura Hanging Bridges. (On the verge of passing out from exhaustion later that evening, we realized that it was only 7:16 p.m.!)
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.
<90 Degrees, Not So Fast
My last post was about the method of measuring the clear opening width of a door that doesn't open to 90 degrees. After reading the codes and the commentaries and having several discussions with someone from the ICC, I posted a graphic of a 32" cylinder passing through the opening, as described by the ICC.
<90 Degrees
I haven't posted for a few days because I've been working on my new FDAI presentation and various other things, but I'm kind of excited about this post because it answers a question that has been floating around for years. Ok...maybe "excited" is the wrong word, but I really enjoy crossing things off the "grey list."
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.
Wicked Restroom Doors
It's been 40 days since I've mentioned a ladies room, and I just saw an application that I can't resist posting about.
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.
Not an Exit
This sign is on the OUTSIDE of a door on the gas station I frequent. I can't think of any reason it would be important to know that nobody will be exiting out of that door (UPDATE: Check out the comments for some interesting insight from a fire marshal.), but it did make me wonder when a sign like this IS required.
Means of Egress Reliability
A while back I posted a photo of an egress door in an indoor soccer arena, which had nets hanging in front of it. I asked my blog visitors to comment on whether they thought the application was code-compliant or not.
