Decoded: Stairwell Reentry (December 2016)
This is one of the code issues I receive the most questions about, so it's the topic of my next Decoded column. Let me know if I didn't answer all of your questions. :)
Decoded: Dwelling Unit & Sleeping Unit Entrance Doors (November 2016)
According to the International Building Code (IBC) and NFPA 101 – The Life Safety Code, most doors in a means of egress are required to unlatch with one releasing operation. One exception to this rule is when a door leads to a residential dwelling unit or sleeping unit...
Decoded: NFPA 80 Requirements for Hinges, Pivots, and Continuous Hinges (September 2016)
With the continued focus on fire door assemblies, it’s important to be familiar with the basic requirements as well as what has changed in the more recent codes and standards. This article focuses on hinge requirements for fire doors...
Decoded: Small Assembly Occupancies (August 2016)
It is not uncommon for a building classified as another occupancy type to include an area used for assembly. For example, a nursing home would typically have a dining room, an office building might have a large conference center, or an apartment complex could have a function room that can be used for parties...
Decoded: Changes to the Life Safety Code for Health Care Occupancies (July 2016)
In case you haven't noticed, there is an interesting conversation happening on my post from earlier in the week about classroom barricade devices. If you have something informative to add in response to the manufacturers of these products...
Decoded: Alternative Methods and Equivalency (June 2016)
I'm on vacation this week and I could really use your help. This is my next Decoded article...if you're willing to check it out and leave any comments below, I could submit it to the editor and try to enjoy a little time off. Please help! :)
Decoded: Change to BHMA Standard for Exit Devices (May 2016)
BHMA is required by ANSI to update and review each of the product standards every 5 years, and an important change was made to ANSI/BHMA A156.3 when it was last revised in 2014. The standard now requires cycle tests for Grade 1 exit devices to include preloading...
Decoded: Safe Dispersal Area Within a Fence or Enclosed Court (April 2016)
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...
Decoded: Fire-Protection-Rated vs. Fire-Resistance-Rated Assemblies (March 2016)
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...
Decoded: Communicating Doors Between Sleeping Rooms (February 2016)
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...
Decoded: Smoke Door Requirements of the International Building Code (Updated July 2019)
Several of you have asked me to update the article on smoke doors that I wrote several years ago. I have looked at this until my vision is blurry, so if anyone is willing to review it for errors I'll offer a bounty for any mistakes found...
Decoded: Code Requirements for UL 294 – Standard for Access Control System Units (December 2015)
The two common code questions that arise regarding UL 294 are - A) which electrified applications are subject to the listing requirements? and B) which components of a system are required to be listed?
Decoded: Delayed Egress vs. Controlled Egress (November 2015)
From the November issue of Doors & Hardware...the table below addresses the requirements for delayed egress and controlled egress, for both the IBC and NFPA 101. Do you know the difference?
Barricade Device Update (October 2015)
In the October issue of Doors & Hardware, I have an article on what took place in Ohio with regard to the state legislation on classroom barricade devices, and another article covering the myths and facts presented at the National Association of State Fire Marshals' annual conference (here's a video version of this information)...
Decoded: Fire Door Closing Cycle (September 2015)
It has been 8 years since the annual fire door assembly inspection requirements were added to the 2007 edition of NFPA 80 – Standard for Fire Doors and Other Opening Protectives. Six years ago, the 2009 model codes referenced the 2007 edition of NFPA 80, making the inspections required by code in jurisdictions where those codes were adopted...
Decoded: Patient Room Doors in Health Care Occupancies (August 2015)
The recent nursing home fire in central China which killed 38 elderly residents is a deadly reminder of the responsibility of these facilities to keep their residents safe. While the code requirements for health care facilities and nursing homes go far beyond the doors, frames, and hardware, there are some important considerations for door openings...
Decoded: Screen Doors and Doors in a Series (July 2015)
Screen doors are sometimes used in commercial or institutional occupancies, where air transfer through the opening is desired. One example of this would be a door leading from a commercial kitchen to the exterior. In some areas of the country where the climate is temperate, this is a common application which consists of two doors in the same opening, one inswinging and one outswinging. It can be very difficult for people with certain disabilities...
Decoded: Double-Egress Pairs in a Health Care Occupancy (June 2015)
There is an IBC exception regarding smoke barrier doors that has to be one of the most confusing and widely debated door-related sections in the code. In the 2015 edition, Section 709.5 Exception 1 exempts smoke barrier doors in some health care occupancies from the requirements that apply to smoke barriers in other locations...
Barricade Device? Think Twice! (May 2015)
I've edited this article and the downloadable PDF - feel free to share it!...There is a question currently under debate in several jurisdictions across the country – should barricade devices be used to secure classroom doors during an active-shooter incident?
Decoded: Electrified Hardware Refresher (April 2015)
There are 7 basic code categories for electrified hardware used to control access or egress, and this edition of Decoded provides a brief refresher on each as well as some recent code changes. Many of these code applications, but not all, fall into the category commonly called “special locking arrangements.”
Decoded: Egress Terminology (March 2015)
As I mentioned in my previous column, there are other factors that affect the quantity and location of egress doors, beyond the general requirements for 2, 3, or 4 exits depending on the occupant load. For example, doors used for egress need to be located remotely...
Decoded: Calculating the Egress Width of Door Openings (Updated July 2017)
A common question when replacing doors and hardware during a renovation is whether one leaf of a pair can be “fixed” in place, or whether an opening can be eliminated completely. It’s very risky to make this decision without consulting the Authority Having Jurisdiction (AHJ), but it is helpful to understand some of the factors that could affect the location, size, and quantity of required exits before preparing your request for the AHJ...
Decoded: Test Your Knowledge (January 2015)
You may have already noticed...I've been taking a little time off between the holidays, but here's something to keep you busy until I'm back in action next Monday...
6 Accessibility Changes to Watch Out For (November 2014)
The 2010 Americans with Disabilities Act (ADA) Standards for Accessible Design went into effect in March of 2012, but there are several requirements that continue to surprise architects and specifiers as well as door and hardware suppliers. These issues can be costly to resolve if they’re discovered after the doors and hardware are on-site, so it’s important to stay current on the requirements...
Decoded: Fair Housing Act (October 2014)
A common misconception is that the Fair Housing Act applies only to federally-funded housing projects, but according to the US Department of Housing and Urban Development, “The Fair Housing Act requires all ‘covered multifamily dwellings’ designed and constructed for first occupancy after March 13, 1991 to be accessible to and usable by people with disabilities. Covered multifamily dwellings are all dwelling units in buildings containing four or more units with one or more elevators, and all ground floor units in buildings containing four or more units, without an elevator.”
Decoded: Calculating the Occupant Load (September 2014)
Many code requirements are dependent upon the occupant load of the room or space in question. For example, the International Building Code (IBC) requires panic hardware for doors equipped with a lock or latch, which serve Assembly or Educational occupancies with an occupant load of 50 or more (the occupant load limit for NFPA 101 – The Life Safety Code is 100 or more)...
The Effect of Oversized Clearances on Fire Door Tests (August 2014)
Rectifying clearance problems can be difficult and costly, so it may be tempting to leave non-compliant doors in place and assume that a little extra clearance won’t affect the performance of the fire door assembly; I can now say from first-hand experience that this is not true...
Decoded: Use Groups and Occupancy Classifications (July 2014)
In Chapter 3, the IBC defines each “use group” and NFPA 101 - Chapter 6 describes each “classification of occupancy.” Both terms describe how the building or a portion of the building will be used, and each of these codes contain requirements specific to certain uses...
Decoded: Key-Operated Locks (Updated December 2017)
I need some help from you...a nice clear photo of a door with the signage described below, as well as the indicator lock. If you have seen one of these in your local area, I'd really appreciate some help with these photos...
