Where can I find the reference in NFPA that It is not accepted by fire codes to pass any utility through the exit that will not serve the exit itself.
I will take it that exit means exit enclosure.
2015 NFPA 101 Section 18.104.22.168.1
Penetrations into, and openings through, an exit enclosure assembly must be limited to the following:
Let me know if this is what you are looking for.
Are you talking about an enclosed stairway or exit enclosure??
Or something else?
If so which building code or standard do you need it from? and year edition
Thank you ….Exit enclosure...I got the answer from Mr.Milton Werner...as shown below.
Thank you Sir...
I understand you were looking for the NFPA requirements but the responses regarding the building code are also viable. You will need to verify the requirements for the governing State building/fire codes and adhere to the most restrictive of all codes and standards adopted.
I just wanted to add to your comment not the extend the discussion of another topic.
The Exchange's method to catalog the questions appears to identify the NFPA 101 for the question. This is sometimes confusing to someone that wants to answer the question using other local or state building safety regulations. However, it is correct to make an assumption that other local building safety regulations may apply. At the state level we have to deal with the adoption of the IBC and NFPA 101. We consider "adhere to the most restrictive of all codes and standards adopted" as doing a comparison and creating another regulation that was not authorized by state statute. Since IBC and NFPA 101 each provide a holistic approach using differing philosophies, we have only the authority to do plan reviews and inspections separately for each code. The state statute has a provision to resolve conflicts between the adopted codes in the state. When conflicts occur between any adopted local or state building safety regulations for non-residential occupancies, NFPA 101, Life Safety Code prevails. The building safety regulation conflicts are the ones that would not allow complete compliance to NFPA 101. The intent was to have new and existing buildings use the most technically current fire safety and other emergencies in commercial buildings which IBC did not offer.
