If a low-energy operator is actuated by a motion sensor, it has to meet the requirements of A156.10 instead of A156.19, which usually means the door must have guide rails and safety sensors. What about the "wave-to-open" switches...are these considered motion sensors?
As a hardware consultant, there were many times that I tactfully pointed out to an architect what I thought was a door-related design problem. My advice was usually ignored unless the issue was code-related. Finally...vindication from Vox and 99% Invisible.
Oh dear. Must be electric latch retraction. :D
As a member of the door and hardware industry, my focus with regard to classroom lockdown is how to provide security without jeopardizing safety. Lt. Joseph Hendry of the Kent State University Police Department looks at the issue from a slightly different (and valuable) perspective...
This Wordless Wednesday photo was posted on the Truck Floor Training Facebook page, by Ian Vandenberg of Travis County Fire Rescue. I just love the extra-large wood wedges...
The new code reference guide is here! Each year, thousands of people receive a hard copy or electronic download of our code reference guide. When a new edition of a code or standard becomes available, I incorporate any necessary changes...
My question for you is this...if you supply, specify, or install wood fire doors, is the glazing typically installed in accordance with NFPA 80 - at the factory or in an authorized wood shop?
"The violations included a window that was screwed shut with three wood screws; an evacuation sign that labeled three exits to the home, even though there were only two; and one of the two exits, leading out to the back, was jammed by a chair that was screwed to the deck..."
If these criteria are met, the fence surrounding the building would not be required to have gates that allow free egress, as the building occupants can gather safely in the enclosed area and wait for emergency responders to arrive...
This Wordless Wednesday photo (from Keith Brown and Steve Bildzok of Allegion) reminds me of how I feel when I walk into my kids' bedrooms. "WHY? What is all of this crap on the floor and why isn't it put away where it belongs? What excuse could you possibly have...
Here's the last whiteboard animation video in the current "Intro to Door Hardware" series...about the design-bid-build process for new construction.
This Fixed-it Friday photo could easily cross over into Wordless Wednesday territory...a fire-rated stairwell door in a day care center, where the installer obviously had an accident that he didn't think was important enough to address...
The possible solutions posted by iDH readers included electrified lever trim, electric latch retraction, delayed egress, a direct-hold electromagnetic lock, a networked wireless lock, or an electric strike. My preference would be...
I'm Wordless about today's photo, sent in by Paul Goldense of Goldense Building Products. But on another topic...please help with yesterday's WWYD? post if you can...
This question comes up quite often, so I hope some of you have insight to share. In the words of my old friend Waller Elliott, "Picture this: You have an existing stairwell door (single), with a 90-minute fire rating..."
Rounding out our "intro" series of whiteboard animation videos...here's an introduction to hollow metal doors. The rest of our whiteboard animation videos can be found on the Allegion Training page, or on the Videos page of iDigHardware.com. What other topics would you like to see addressed in future videos?
I don't like to be critical of peoples' work, but this Fixed-it Friday retrofit could use a little TLC. Thank you to Deputy Jeff Tock of Allegion for thinking of me whenever he sees a problematic door. ;)
After yesterday's discussion in the comments about the lack of feasibility of annual fire door inspections, I think it's time for a reminder of how much protection a closed door can be during a fire. While inspecting all of the existing fire doors may seem like an insurmountable task...
Today's Wordless Wednesday photo was sent by Nolan Thrope of Allegion...this is a cross-corridor fire door in a school. The closer is missing as well as the obvious hinge problem. Sadly, this type of neglect is not uncommon. :(
I was so happy to arrive at the hotel last night and find this photo from Austin Bammann, of Central Indiana Hardware. This is a great illustration of the variations and unintended patterns that can occur with rotary cut natural birch doors ("To infinity...and beyond!")...
Just when you thought there couldn't possibly be enough to know about panic hardware for another whiteboard animation video...here's one that talks about the different types of panics available and why you might choose one over another.
I guess this application would work if there wasn't a real need for security, but if someone is able to press the touchpad from outside the gate, they will be able to enter the secure area after waiting 15 seconds. It's a lot of money to spend for security that can be so easily defeated. I'll give them credit for installing the signage though!
In yesterday's post I wrote about a video on classroom barricade devices that had gone viral. In the first 36 hours or so, the video had 18 million views. 18 MILLION! Almost 600,000 people have shared the video on Facebook, and about 6,500 people have commented. This is an amazing (and somewhat disturbing) example of the power of social media...
A video about classroom barricade devices - a particular company's devices, actually - has been posted on a Facebook page and has gone viral. Right now, about 14 hours after it was posted, it has over 3 million views. There are over 1,000 comments - many of them in support of this idea...
Just when I think I've run out of questions and potential pitfalls, one shows up in my inbox. A while back I wrote an article for Doors & Hardware, addressing the required mounting height for operable hardware. The model codes and accessibility standards require operable hardware to be mounted between 34 inches and 48 inches above the floor. I noted in the article that some states have adopted different requirements for mounting heights...
Do you have questions about low-energy automatic operators or the standards that apply to them? Maybe this will help...
Sort of like the chicken and the egg, this Fixed-it Friday photo from Steve Turner and Ray Valentine of Precision Doors & Hardware made me wonder...was the closer added because the automatic operator wasn't closing the door properly, or was the automatic operator added because the closer required too much opening force? Or one or the other stopped working completely but was not removed?
I've been working on updating my code reference guide - adding new information from the 2016 edition of NFPA 80 - Standard for Fire Doors and Other Opening Protectives. There are quite a few changes to NFPA 80, and although this edition of the standard won't be used in most jurisdictions until the 2018 model codes are adopted, some of the changes may help to clarify the requirements of previous editions...
This Wordless Wednesday photo from Scott Straton of Allegion requires a bit of explanation. In Scott's words..."My niece was working out at 3:00 AM (she is an avid runner and had an early flight) at a hotel fitness room. When she went to get a drink of water, the lock failed and she was not able to get out..."
Here's a new whiteboard animation video explaining the basics of thresholds and gasketing, including the related accessibility requirements...
Last week I got an email from an architect working on a renovation project at a college. Part of an existing classroom building is being converted into a new administration area, and the project scope includes preparation for an access control system that will be designed later. The electrified hardware was included in the current project, but the access control readers have not yet been added and the system is not powered up...
I think if I passed this Fixed-it Friday door while visiting this memory care unit my mind would have gone right to the NFPA 101 section that addresses exits disguised by murals in certain types of health care units. Maybe I wouldn't have focused on the actual artwork, but as Gail Erickson of Allegion pointed out when she sent the photo ("I wonder how many times the alarm goes off when they go to get a cup of tea?"), what is depicted in the mural could affect how well the disguise works...
We've been working on a new series of whiteboard animation videos...here is one of my favorites!
I love it when non-hardwarey people send me photos of egress problems or faulty fire doors. Today's Wordless Wednesday photo is from my friend Gia Jobin, who saw this door on a university campus and recognized that there was a problem...
Yesterday someone asked me about the preferred lock function for a lactation room (aka mothers' room, lactorium), and I realized that I had not written about this before. Back when I needed a lactation room, one of my coworkers changed the passage set on my office to a privacy set...
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...
Today's Fixed-it Friday photo was posted on the Truck Floor Training Facebook page by Brandon Stroud, a firefighter from Anderson, South Carolina. I don't know whether to laugh or cry...
After 7 years of posting a new piece of door & hardware information on this blog every day, it makes me very happy to receive a new question that I haven't thought about before. Last week's question was related to the solid bar gasketing designed to allow closer shoes (and other hardware) to be attached directly to the gasketing...
This public radio broadcast about egress and the accompanying article from 99% Invisible are both FABULOUS. Some of the old-fashioned inventions for exiting a building remind me of the "new" school safety and fire escape ideas...
When I take time off for the holidays, I often leave a crossword puzzle or some other activity in case you decide to check in while I'm away. This time I'm posting the first of 4 Decoded classes for you to check out while things are relatively quiet...
Questions on smoke gasketing continue to come up, so the Steel Door Institute asked me to write about it for their quarterly newsletter. You can subscribe to their newsletter here...
This photo from Kristi Dietz of LaForce, Inc. (check out their blog!), is not just your everyday Fixed-it Friday photo. It is one of my favorite Fixed-it Friday photos OF ALL TIME! And no, it's not code-compliant...at least not in any jurisdiction that I know of...
We've all seen this somewhere. Did you say something? Was the problem resolved?
Nobody ever thinks it will happen to them...a fire in their home, school, or workplace. But according to the National Fire Protection Association (NFPA), U.S. fire departments responded to an estimated annual average of 5,690 structure fires in educational properties between 2007 and 2011. I've written many times about how important it is...
Last Friday, the Ohio Board of Building Standards posted a 434-page business impact analysis containing all of the comments submitted with regard to the proposed code change on classroom barricade devices. My comments to the board included a comparison of the recommendations made in the July 2015 OBBS Final Report vs. the proposed code language...
When Jess Dey found this closer on eBay, I was shocked to see such a beautiful potbelly closer! I've never seen a closer with decorative accents - usually architects want to hide the hardware. As it turns out, this closer from the Standard Oil Building in San Francisco was rescued from the trash heap as a standard closer...
Every December I weed through my inbox so I can start fresh in the new year. I get A LOT of email...my inbox is currently down to only 525 emails waiting for some sort of action on my part. I just found an email that included a link to an article from NFPA Journal...
These photos were shared on the Truck Floor Training page on Facebook, and are posted here with the permission of Chris Morgani of the Fort Myers Beach Fire Department. In addition to the obvious problem, the door is welded shut. Maybe it's not a required exit, or maybe someone made an uneducated decision. We will probably never know...
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...
NFPA 80 - Standard for Fire Doors & Other Opening Protectives no longer includes a prescriptive requirement for certain pairs of fire doors to have astragals. In the 1999 edition of this standard (and prior editions), an overlapping astragal was required for pairs of doors rated for more than 1 1/2 hours. In the 2007 edition, the requirement for an overlapping astragal was removed, and the use of the astragal is dependent on the manufacturer's listing procedures...
