WWYD? Classroom Acoustics
Is compliance with the ANSI-ASA S12.60 standard required for any school projects? What is the current practice for classroom doors? Sound gasketing? STC-rated assemblies?

As a child of the 70's and 80's, and now a mom of three young adults, I once resisted the idea of keeping classroom doors locked during class, but times have changed. WWYD?
I'd like to compile some information on glazing films that can be used on glass in doors and sidelights, including fire door assemblies. I'm hoping that some of you have insight to share.
I'm finally writing this post so I can find the answer quickly next time...today's Quick Question is this: Are doors serving single occupancy restrooms required to be self-closing?
Although at first glance I was Wordless, I'm wondering...what would you do? On the other side of this door is an unoccupied roof, four feet down from the occupied space.
I've seen this application hundreds of times, gymnasium fire doors with applied padding. But is applied padding allowed when the doors are fire rated? WWYD?
Paul Timm of Allegion sent me this photo, and it illustrates a really great question about doors in a means of egress. Is there something specific in the codes that would prevent this?
Some states and local jurisdictions have already adopted requirements for classroom doors to be lockable. Should the model codes require locks on classroom doors? WWYD?
Today I have a follow-up question to yesterday's post about stairwell reentry. Neither of these questions is addressed in the codes, so I am looking for any insight from the field.
In some buildings, a stairwell may have more than one door serving a floor. In that case, are all of the doors required to allow reentry, or could one door be designated for this purpose?
When a stairwell door unlocks (or is always unlocked) to allow building occupants to leave the stairwell if it becomes compromised during a fire, what happens next? WWYD?
The doors on this hotel bridge could be lockable if they met the requirements of the new section of the I-Codes addressing egress doors serving exterior spaces. Does anyone want to take a guess on what would be mandated by that section?
This grocery store's manager stated that the justification for this closed exit was that people were walking out of these doors without paying for their merchandise. I have my own thoughts about this situation, but I'm wondering...WWYD?
One of our specwriters contacted me earlier this week, in search of the Quiet Doorman product. Does anyone have a source for this panic bar retainer or something similar? WWYD?
As a former specwriter, I can see a potential for problems if a plate that is required to be installed with screws is specified for a fire door that requires installation with adhesive. Is this an issue that arises in the field? WWYD?
If you are responsible for inspecting fire door assemblies or keeping them code-compliant, you already know that one of the most common challenges is related to perimeter clearance. Do you have a few minutes to share your insight?
This exit serves an aircraft hangar in a military museum and is properly marked - there is an exit sign above the door. What do you think about the additional exit path marking projected onto the floor? WWYD?
If you are an AHJ or a fire door inspector, or have used listed plates to cover holes in fire doors, please share your insight. Are there limitations on hole size, door material, or fire rating? Is permission from the door manufacturer required?
Yesterday in an airport I saw a bank of interlocks and an adjacent pair of doors with delayed egress locks. What do you think about this application? Do some AHJs require delayed egress doors where interlocks are installed? WWYD?
There isn't one lock function that works for every school - in some schools, only staff members with keys are able to lock the classroom doors, and in other schools anyone can lock the doors. WWYD?
Unless specifically exempt from the labeling requirements, each component of a fire door assembly must be labeled to show that it is acceptable for that purpose. Is the fire door label in this photo compliant with NFPA 80? WWYD?
When a stop or holder is mounted on the floor, at what point does it become a tripping hazard? I have not found a specific reference in the model codes or referenced standards on the acceptable mounting location.
I have an opinion on this question that I will share tomorrow, but I'd love to know how you are seeing the model codes applied in the field. A question arose recently regarding which doors require panic hardware, and the answer required "proof" from the IBC...
It is not uncommon for a building to have a means of egress that passes through a swimming pool enclosure. I have run into this several times before and I'm wondering how you are seeing it addressed in the field. WWYD?
This photo is a great illustration of a problem that has come up before, and I don't have a good answer. What solutions have you seen for double pairs of fire doors like this? WWYD?
Have you seen lever handles purposely mounted in the vertical position? If you are an AHJ, do you have concerns about this application? Is the hardware violating a code or standard when mounted this way? WWYD?
Would a pair of doors with a hollow metal removable mullion and locksets on both door leaves be more reliable and require less maintenance than a pair with flush bolts and a lockset? What are the challenges with this application? WWYD?
Many school security experts advise schools to keep classroom doors locked at all times, but is that feasible? How do we overcome the challenge of security vs. convenience? WWYD?
Last week, I received some photos of a pair of fire doors with LBR fire exit hardware installed without the auxiliary fire pin. Apparently the door manufacturer's listings did not require the pin, but the hardware listings do. WWYD?
Last week I received an email from an architect, asking if I would update a post from 2009. Naturally, I was curious about how this old information was being used.
Every so often I ask the readers of iDigHardware to weigh in on what you are seeing in your state or local jurisdiction. Today I need your help on the topic of accessibility symbols - please share your insight in the comments.
Logan Piburn sent me these photos the other day and asked for my opinion. Based on the model code excerpts in this post, would you consider these egress doors code-compliant? WWYD?
Does anyone out there have an example of a lockdown plan meeting the requirements of the International Fire Code (IFC)? I'd like to share it with the life safety manager of a university who is looking to see what other facilities are using. WWYD?
On behalf of an iDigHardware reader, I need help from someone with a really long memory or a better filing system than mine. Where did the limit of 30 pounds to set the door in motion and 15 pounds to open the door fully come from?
Is there a code requirement that would prohibit the installation of automatic operators above an acoustical tile ceiling? Would the working space required by NFPA 70 - National Electrical Code apply here?
I don't think I've written about this particular application before, but I do think it's a valid option for classroom doors. I'd like to know what you think, and if there are potential problems or concerns.
One common difficulty regarding ESE classrooms and classrooms for very young children, is the possibility that a student will leave the classroom through an exterior door and end up in a dangerous situation. WWYD?
The balcony in these photos is located in a conference center. It's not too high above grade, so yes - you could jump off, but generally that's not how the egress requirements work. What would you do?
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?
Today is the second day of a 3-week work trip for me, where I will be doing a lot of training and attending two conferences. In a perfect world, I would have already written and scheduled 3 weeks worth of blog posts...
This week marks the 30th anniversary of a tragic fire at Imperial Food Products - a chicken processing plant - where 25 workers lost their lives. Could an agreement between OSHA and the USDA improve workplace safety?
Thank you for all of your comments and feedback on last week's Fixed-it Friday post - I really appreciate the help! I'd love to hear what you think about fire door assembly labels as an educational tool for building occupants.
I received this photo of a bank of doors with delayed egress panic hardware from Jim Elder of Secured Design LLC, and we got to chatting about some delayed egress questions. I'd love to hear what you think. WWYD?
I'm wondering what you think about this door opening...it's kind of an interesting one as door openings go. I have never thought about using a combination of panic hardware and a lockset with an electric strike. WWYD?
The IBC states: Doors in the means of egress shall be readily distinguishable from the adjacent construction and finishes such that the doors are easily recognizable as doors. Do you think this door is "readily distinguishable"? WWYD?
This is an important update to an earlier post about the code changes related to "occupied" indicators on privacy sets. The IBC change applies to family and assisted-use restrooms, but not to all single-user restrooms.
I'm sure you can all see the problem with this apartment entrance...how would you mount a door closer on this side of the door?
I'm having a hard time making the connection between the NEC classifications for hazardous locations and the requirements for access control used in those areas. Are you an electrical expert?? I'd love some help with this!
I have not commonly seen automatic-closing devices on fire door assemblies released by the sound of the fire alarm system vs. the detection of smoke, but maybe it's a viable option for the US market? WWYD?
We are now beginning a new code development cycle for the International Building Code, and NFPA 101 - Life Safety Code will follow soon. This gives us an opportunity to propose changes to the codes that affect door openings the most...
