This question is coming from a concern that I have over sprinkler riser systems device installation/replacing such as pressure, tamper, water flow, switches and related low voltage devices on any working riser system and the requirement for any technician to be able to perform, and a State licensed Limited Energy technician performing this work.… (Show more)

Pressure requirement for Combined sprinkler and FHR system

Hi.. As per NFPA 13 , 100gpm flow is considered for hose stream (inline with AHJ) in addition to the sprinkler demand. Accordingly, hydraulic calculations are prepared. Is it necessary to achieve minimum residual pressure of 65 psi where the FHR nodes are provided ? Or any residual pressure with 50 or 100 gpm is acceptable ?

Hose allowances in NFPA 13 are not required to have a minimum residual pressure unless the hose connections are installed downstream of an alarm valve or system valve.

The testing requirements of Section 5.3.1 of the 2020 NFPA 25 for sprinklers will give your answers for what an aged sprinkler system needs to comply with. It is highly doubtful the entire sprinkler system would need to be replaced to a more current current standard. We had some health care institutions that were 50+ years that had not any major…

Unlimited area buildings and construction types

I understand that a 250.000 square feet, fully sprinklered, ordinary hazard warehouse can be classified as an unlimited area building per NFPA 5000 and the IBC, without any construction type requirement. Are there any other codes in the US requiring some kind of fire rating for the structural members of such buildings, or can you simply go for a… (Show more)

If there is an elevator inside a dwelling unit, does the upper floor require disabled refuge area?

Does anyone see any issues with putting an elevator in a dwelling unit? I'm involved in some developments in which the architect wants to put 2 story elevators in double story apartments and double story houses. The problem I have with this is that NFPA 101 says that all areas of a building which are accessible to people with sever mobility… (Show more)

Ben: That would be my understanding. There will be a future trend because of higher costs of land, foundations, and roof systems that single family homes and apartment dwellings will be designed to include multiple floors and the residential elevator will be demanded by the consumers. The means of escape will be limited in the upper…

Nonrechargeable (nonrefillable) extinguisher

NFPA-10 mentions Nonrechargeable (nonrefillable) fire extinguishers by definition and states they are excluded from the 6 year test with a lifespan of 12 years. Are they allowed by NFPA code in a commercial office? If so, what is the annual inspection requirement?

Daniel, Having taught many, many hands on extinguisher classes I can tell you that about 99.5% of the population cannot extinguish any fire with a non rechargeable 1A 10BC fire extinguishers. It takes an expert with extinguishers to accomplish anything with such a small extinguisher. In most offices I had to protect over the years I used 10 lb.…

I agree with rdfacm02's good sense and judgement about the termination as shown in Figure A.7.8.4 of the 2021 NFPA 96. When the architect hands you a drawing like they did, to me, this is the only comment you would be able to give them. Where the architect decides the rooftop termination is an aesthetic thing they were not envisioning, then the…
