Air supply piping from and air compressor. I see that some air compressors are connected with stainless steel braided hose. Does this hose have to be listed for fire protection use? I can’t seem to locate any relevant information in NFPA 13.
Hi, I'm working on a hangar project which is a Membrane-Covered Rigid-Steel-Frame-Structure Hangar. The hangar has a 6800 m2 fire area. With regard to fire protection system design as per NFPA 409-Chapter 9, I'll proceed with high-expansion foam system as specified in 220.127.116.11. 18.104.22.168.3 states the following "The application total discharge…(Show moreShow less)
Section 9.14.2 has several protection options, but It seems that low level high expansion foam system is not required to have a high level sprinkler system. It seem that section 22.214.171.124.3 is only applicable if both high level sprinklers and low high expansion foam system are installed. Hangars under 1115 m² with hazardous operations are…
Hi, the topic is fire sprinkler system in a big aquapark. What about internal swimming pool with many plastic slides. I think above swimming pool sprinklers are needed to protect construction of building. What about density in this area? I cant imagine sprinkler under slides, there will be obstruction. What about it? Best regards Joanna…(Show moreShow less)
If codes such as NFPA 1, NFPA 101 or local codes requires the building be sprinklered, then sprinklers must be provided. Unless the slides are made of a highly flammable plastic, the discharge density will likely be small. NFPA 13 has a section for the omission of sprinklers, that the slides might or might not apply.
The criteria I know are as follows According to NFPA.13 chapter 17, ESFR protection provided with in rack sprinkler. Maximum ceiling/roof height is 45ft. ============================================================================= Do you have the following criteria? "no limits on building height with in-rack sprinklers." Thank you…(Show moreShow less)
If you want a "no limit building height with in-racks" in the 2016 version of NFPA 13, you'll have to apply CMDA or CMSA criteria. Otherwise, if ESFR are required, use the new alternative in-rack arrangements provided in the 2019 edition of NFPA 13.
In Laser Tag Arenas, there are team Bases. Each project has different themes and therefore have different designs for Bases. Most Bases have an overhead element connected to 2-4 walls. Question: What specific rules would these structures need to follow, in-order to NOT need a sprinkler under / inside the structure?
Does this building require a suppression system? Conditions: Existing motel built in the late 1960s Abandoned (4-6 years) Under remodel (new drywall, plumbing, electrical, mechanical) 60 units 12,000 sq foot building Fire resistive (cement block) construction Two stories Rooms exit to the parking lot…(Show moreShow less)
Hello Milt, I think your axiom makes my argument very well against others than the organization who wrote the codes and standards interpertating them. When I worked for the DoD and all 7 of us got together and a code question came up at times there were 2-5, 4-3 etc interuptions with excatlly the type of discussion going on that you discribe in…
Is it sufficient to install the normal lights connected to generator or we have to install emergency lights operated by batteries inside the hospital and which area required to installed emergency lights and which NFPA cover this matter
Is it ok to use pendant sprinkles in an open ceiling configuration if the distance from the sprinkler deflector and the ceiling are within 12 in. I have been told that only upright sprinklers are allowed in that situation.
In the NFPA2001 standard, the definition for shall says it is a mandatory requirement. As far as I know, something is only mandatory if stated in Legislation, Regulations or Official Acts? Does this mean the parts that are "mandatory" are backed by regulations? if yes, which ones?
Piggy backing onto this, the shall within a standard is a mandatory requirement for compliance with the standard. The AHJ makes the final determination if the standard is a mandatory requirement for compliance with local building codes and ordinances.
