Does the NFPA-101, 2012, exempt Temper Rise in stairwells, regarding fire doors, if the building is fully sprinkled?
If so, can you give me the chapter, section, and verse.
Ok what is Temper Rise
The doors have to meet the required rating, no matter if the building is sprinkled or not.
Thank you Paul.
It's Temperature Rise. Sorry about that.
There are many cases where a wall is rated for 1 hour and a 20 minute fire door is allowed. Or a non rated accessory is allowed on a fire door that is not allowed on others with the exact same fire wall rating. These 101 exemptions exist mostly in buildings that are sprinkled, but not always.
I usually can find the code answer easily however, I was challenged about Temperature Rise in stairwells by a Door and Hardware (DHI) Code expert that said, paraphrasing "Temperature Rise was no longer an issue with fire doors if the building is fully sprinkled. It is in Chapter 7 of the 101." I couldn't find the verse.
I have looked through the 2009, 2012 in both chapters 7 and 8 and have found nothing.
Temperature Rise is a very important part of some fire walls. I can't see the justification for allowing this exemption.
I have emailed this gentleman about the exact chapter ,section, and verse, but have received no return response.
I am going to be teaching a class on Temperature Rise and I was hoping that someone could help me out.
I am wondering if the person was just making a general statement. Kind of yes it will get hot, but at some point the sprinkler system will activate, and keep the temperature down.
Compared to a non sprinkled building, where the door could take the full heat of the fire.
Send your question to the person's email in this link, and you should get a great answer:::
I see no reduction in the IBC for a rated stair door in a sprinkled building.
Temperature rise does not reduce the fire doors rating. Temperature Rise is an additional rating along with the fire and smoke ratings. It is the rate of heat increase of a fire rated door or wall in 30 minutes.
There are 3 categories; 250 degrees, 450 degrees, and 650 degrees.
A 250 Degree Temperature Rise door can only increase 250 degrees from the ambient temperature on the safe side of the door. So a rooms ambient temperature is 65 degrees, plus 250 degrees temperature rise, equals 315 Degrees.
If you are passing down a stairway from the 12th. floor and the fire is on the 10th., The 10th. floor fire door is hot and can severely burn a person who is just passing by, or could stop a persons' egress to safety because of the intense heat. Temperature rise products reduces the amount of heat transfer that passes through a door or wall so people can escape without harm.
You can see why I need the correct information about the possible temperature rise exemption and why exempting it is dangerous. It was a bold statement that needs to be backed up.
Thanks for input Paul.
This DHI person was stating a code fact.
The other thing is normally you start with the hourly rating of a door, not temperature.
22.214.171.124.1 Door leaves shall be arranged to be opened readily from the egress side whenever the building is occupied.
126.96.36.199.2* The requirement of 188.8.131.52.1 shall not apply to door leaves of listed fire door assemblies after exposure to elevated temperature in accordance with the listing, based on laboratory fire test procedures.
A.184.108.40.206.2 Some fire door assemblies are listed for use with fire pins or fusible links that render the door leaf release inoperative upon exposure to elevated temperature during a fire. The door leaf release mechanism is made inoperative where conditions in the vicinity of the door opening become untenable for human occupancy, and such door opening no longer provides a viable egress path.
Only temperature thing I found
Look at page three,,, Item 4:::
Still does not say anything about fire sprinkler:
Sorry have not done hardly any high rise::
Ok found it in the IBC
2015 IBC section 716.5.5 So he was telling you correctly per IBC
Not the wording::
Section 716.5.5 includes a requirement for temperature rise doors, but the exception exempts buildings that are equipped throughout with an automatic sprinkler system.
Will not let me cut and paste:::
My guess in 101 it would be in chapter 8
Exception may not be in 101???
send and email to the person above and ask
The NFPA-101, 2012.
Look at the Table 220.127.116.11, and 18.104.22.168, also look at 22.214.171.124.1. The (T) refers to temperature rise.
Temperature rise doors are typically in stairwells, occupancy separation, and special occupancys.
The purpose is to not have people burned passing by a door that has a fire raging on the other side. That is why the glass is restricted in temperature rise doors. Porcelain glazing such as Fire Lite glass does not stop the heat transfer and therefore can only be used within the 100 sq.inch requirement on a 90 minute fire rated door. You will notice that Fire Lite carries a (NT) meaning it can not be used on a temperature rise door that has more than 100 sq. in. for a 90 minute door.
