Variable Door Thickness
I've specified hardware for A LOT of doors. Thousands. But I've never worked on a door like this one, where the door thickness varied from top to bottom. When you have a door with an unusual thickness, you need to consider the interface between the lever trim/control, the lock body, and the panic hardware, along with the length of the fasteners and cylinder. With a mortise lockset or a mortise panic like this Von Duprin 5575 device, the location of the lock body within the door thickness factors into the equation. For example, if it was a 3" thick door but the lock body was installed at the push side face of the door, only the connection between the lever and the lock body would need to be addressed. If the lock body was installed at the pull side face of the door, only the connection between the lock body and the panic hardware would need to be addressed. If the lock was centered in the door thickness, both connections would be affected, as below.

CBS Chicago: Would-Be Burglar Thwarted After Pulling Door Marked ‘Push’
The fact that this door swings in instead of out seems to confuse the burglar enough that he can't figure out how to get in. However, I would NOT recommend inswinging doors as a security measure! Considering that people generally try to exit the way they came in, I think this opening could be an egress problem unless it is serving a very small bar. What do you think?

From Stephen Richardson and Joe Beeman of Allegion, here's a hinge modification they saw recently. Would you consider this acceptable? Why / why not?

BUILDINGS BUZZ – Voices from the Industry
I always enjoy having a chance to work with facility managers to make sure they're up to date on what's new in my world - whether it's a new product or a recent code change. I often answer specific questions and help with product applications one-on-one, but I really appreciate the opportunity to connect with them en masse.

Timbuktu Bar & Banquet Hall Fire
Every day I read news articles about fires, looking for references to fire doors or egress doors. I'm sure you can imagine my reaction when I see an excerpt like, "The bar was open and occupied at the time of the fire and a fire wall and fire door stopped any fire damage from occurring there, according to the report."

Q&A: Life Safety Code 2012
A few years ago I met Brad Keyes of Keyes Life Safety Compliance, who is a terrific resource when it comes to life safety questions about health care facilities. When I received the question below I sent it to Brad, and his answer was so comprehensive and helpful that I asked if I could post it here. It is relevant to all types of health care facilities, not just ambulatory health care. Thank you Brad, for allowing me to share this information!

FF: Random Creativity
If any of you attended DHI's AH2 class in Savannah, Georgia back in the Good Old Days, you may have had one of my all-time favorite instructors - Bob Jutzi. I actually use a lot of his techniques when I teach, to try to make my classes more engaging and dare I say "fun"? I don't have a flat-cat Earl, but I still have the monkey from my AH2 class (and a monkey arm from another year). Bob sent me the photos below so if you want to leave him a "howdy" you can do so in the comments.

Manhattan High Rise Fire
On January 5th, a fire in a Manhattan high-rise apartment building resulted in the death of building resident Daniel McClung, who was found in a smoke-filled stairwell. Several other residents were injured, including Mr. McClung's husband who was also found in the stairwell. The fire appears to have been the result of an overloaded extension cord or power strip. The apartment's resident was not at home when the fire started, and reportedly opened his door upon returning home, saw the fire and escaped leaving the door open. This provided oxygen to the fire, and allowed the smoke and flames to spread.

Back to Cape Cod
A few years ago I took my family to a resort on Cape Cod for winter break, and I spent this past weekend at the same resort. On our first visit, I found a lot to write about...the hinges on all of the cross-corridor doors had been modified (sometimes very badly) and were no longer code-compliant for fire doors, the fire doors connecting the 8 buildings were propped open with wedges and the latches had been removed, the swimming pool egress doors were questionable, and there were a few other issues.

FF: Creative Doorknobs
The other day I ran across this glass globe doorknob, which allows you to see into the next room before you enter. Pretty cool design, but not without its challenges, especially if it's not available with 1-way viewing. I could use it to spy on my kids to see if they're playing video games when they're supposed to be sleeping, but I don't want them to be able to check to see if the coast is clear before leaving their bedroom to make a run to the cookie jar.

WW: Overlapping Astragal
Last week on The Building Code Forum, one of the members mentioned that their local police department recommended the installation of overlapping astragals on the exterior pairs at their schools. This left me WORDLESS! It definitely feels like 2 steps forward - 1 step back some days.

WWYD? Connecting Classroom Doors
Many classrooms have a door connecting to the adjacent classroom. Correct me if I'm wrong, but since most classrooms do not require a second means of egress, I think those doors are typically there for convenience. I tried to find something in past codes that would have required the second door, but so far I only see the requirement for a second means of egress when the occupant load reaches 50 or more. (Note: There are some situations where a classroom may need to have a second means of egress because it is not located on the ground floor.)

School Security in the News
If you search Google News for the words "school" and "security", the search engine will return millions of results. There are stories about many cities, states, and school districts working on plans and funding to increase the safety and security of their schools. There are reports about incidents at schools, and products that may help improve security. It's tough to wade through it all. The following articles address the topic with a slightly different focus.

School Security After Sandy Hook
Saturday, December 14th, marked the one-year anniversary of the senseless violence that took the lives of 20 children and 6 staff members at Sandy Hook Elementary School in Newtown, Connecticut. I don't think there's any doubt that the tragedy has resulted in increased focus on the security of our schools.

I will admit...new mortise locks can be pricey. Luckily they usually last for decades. But there comes a time when even a heavy duty mortise lock needs to retire.

WW: Ice Time
This photo, from an ice arena, gives me the chills. Ice rinks are notoriously difficult locations for doors and hardware...lots of abuse, often a high occupant load, humidity and corrosion issues, and other contributing factors. In case you don't see the problem right away, look at the top of the mullion. Angle brackets have been bolted to each door, and there is a pin inserted through one bracket, through the mullion, and through the other bracket. Someone trying to exit through these doors would likely have no idea why they won't open.

Swing Free in School?
Over the weekend I visited a local high school for a swim meet. Right away I noticed MANY pairs of fire doors equipped with LCN Sentronics, which are designed to hold the doors open until the fire alarm sounds and then close the doors to deter the spread of smoke and flames. Some of these doors were propped open with wood wedges (uh-oh). When I took a closer look, I realized what the problem was.

FF: STOP!
When you're faced with an opening where a floor stop or wall stop just won't work, you could use an overhead stop. If that's not enough protection, you could use a door closer with advanced variable backcheck (AVB), which starts the backcheck (cushioning effect) earlier in the opening cycle and keeps the door from gaining momentum. Or you could get creative and make your own stop, cover it with carpet so it looks pretty, and then buy a new door...

WW: Look Closer
I just had an idea. I'm putting together an online code class for my coworkers, which will be available to others outside of the company next year. The way I like to teach about codes is to explain the intent behind the requirement, show examples, reference the applicable section of the code, and preferably to break up the education into small chunks so it's easier to absorb over time. The way I initially tried to learn was to read the code books and highlight the sections, but it didn't really stick with me. So many people email me to say, "I know the code says something about *this*, but where is it?"...something they have read or heard may have left an impression on them about the requirement, but it didn't settle into their brain for the long haul.

FF: Lockdown
Eric Paul of Ingersoll Rand Security Technologies sent me these photos of another school lockdown product that a local school was using. The lock is kept locked, and the add-on product keeps the latchbolt retracted until there's an emergency and the teacher needs to lock the door. This product can not be used on fire doors, which need to latch. Have any of you ever seen or used this product? Comments?

WW: Down at the DMV
I find the Department of Motor Vehicles so frustrating that one year I actually cried because after waiting over an hour they said I didn't bring the right utility bill. AND...my car got hit by someone taking his driving test in the parking lot (he failed). It might have all been worthwhile if I could have spotted an exit at the DMV like this one, sent in by Lisa Augerson of Ingersoll Rand Security Technologies. According to Lisa, the DMV person said they keep it unlocked during business hours.

Hobbit Doors
Hobbit doors are all the rage right now...you can find hobbit door jewelry, cookies, outlet covers, ice cream sandwiches...I would like a real one. Not a tiny real one - a 5-footish, round hobbit door with a knob in the middle. Now I just have to figure out where to put it. If I made a hobbit hole in the back yard I could hide from the kids in it.
