It could be a problem with nfpa 13 vs building code. I am not versed at all in egress, fire ratings etc., but I would bet floor area does matter. Do the building codes make you count both floors when the vertical openings are not protected? I guess I am looking for consistency.
This is going to open up a can of worms. There are a considerable number of buildings that have been designed only counting area's per floor with openings to the story or stories above. Offices, malls, apartment buildings and the list goes on.
There is a retail store that is 100,000 sq ft and two stories. There are vertical openings and sprinkler protection per 8.14.4 (nfpa 2002 ed), smaller ones with sprinklers around and the larger ones that do not require sprinklers. I am told that because of the larger vertical openings (that...
Taking that most AHJ's would follow the standard word for word, the stairway's that do not have access to the roof would need connections that penetrate the roof. Where does it say that because there is only one stairway that has access to the roof we only need the one connection on the highest...
Existing building with 5 stairways and flat roof. Only one of the stairways has access to the roof. Each stairway has an existing standpipe. NFPA-14 7.3.2 (5) states that hose connections must be at the highest landings of stairways with stairway access to a roof and on roofs with a slope of...
All very good points and I do agree that per the code this space is not concealed and should be protected. Without it being closed off there are alot of "what ifs" that can be played out here. This is a forum where these types of situations are and should be discussed. That is why I wrote...
Existing 32' warehouse with sprinklers and they want to store roll tissue to 20'in half of the building. Insurance company is making them put a false noncombustible ceiling in at 25'. Will provide new system for below. Existing system above the ceiling to be removed due to weight concerns...

You are correct on the use of 4.8K without a strainer. I should have looked it up in 13. I knew there was a reason for not using the 4.8K's up here in the north. Its because you can only use the 4.8K's on wet systems. Our attic systems are usually dry.
I agree with LCREP. You are not allowed to store above the tires without the required protection of the combined height of the tires plus other storage. That height would need to be protected as if it was all tire storage.
Can anybody explain why in NFPA 13 you can use either QR or Res Sprks in a residential (light hzd) facility and in 13R you can only use Res Sprks (there is an exception in 13R to use QR's if no more that 4 sprk in a unit). Any thoughts would be appreciated.
