Gosh, 73-feet is a long distance to drag fire hose from the valve at the exit 
door along the length of the rated exit passageway. 
If there’s no occupancy openings in the length of the exit passageway, then 
maybe you could ask the AHJ if he wants a hose valve at the inside end of the 
exit passageway. 
If that’s the case, then I don’t think you need to add the additional 250-gpm. 
Just use 500 plus 250.
Just my opinion.

[Sprinklerforum] Re: Standpipe NFPA14 2019

2024-05-10 Thread Steve Leyton 
Do you have a hose connection on the 1st floor landing of the remote standpipe 
stairwell in addition to the one at the exit passageway door?   And is there 
access to occupiable areas on the first floor from the passageway or stairwell?

Obviously, two or more hose connections supplied by a feed main on a single 
floor is a horizontal standpipe by definition, but it would seem to me that in 
this type of egress system that would be redundant or not of value depending on 
where a firefighter would be going with the water after connection to one or 
the other hose connection.

The foregoing does not represent any opinion or interpretation of the standard 
on behalf of NFPA or the NFPA 14 Technical Committee.

To all,
I have a 4 story building with 2 exit stairways I am installing a class I 
manual wet standpipe combination sprinkler system. The remote stair is on the 
interior of the building and has a rated exit passageway  on the first floor 
that is 73' long. I am placing all hose valves on the main floor landings and 
one a the exit door of the exit passage way.

I am planning on calculating 500 gpm from the remote stand pipe and 250 for the 
2nd standpipe. The exit passage way hose connection will be fed by a  2/12 
lateral pipe fed from the  4" horizontal supply to the remote standpipe as it 
pass by the exit passageway.

Do I need to include an additional 250 gpm in my calcs at the hose valve at the 
exit passageway?

Thanks

I hope are all doing well,

I am referencing Section 8.6.2.2 of the NFPA 13 (2022), which mentions that 
ESFR sprinklers can be used with premixed antifreeze solutions, provided they 
are listed. Based on this, would it be possible to protect a cold storage 
warehouse (refrigerated) using ESFR sprinklers along with the recommended 
tables if a listed sprinkler compatible with a premixed antifreeze solution is 
available? Has anyone implemented this solution before?. Due to certain 
constraints, using dry barrel sprinklers is not possible, and implementing dry 
pipe systems would require rack sprinklers, which are troublesome.

Additionally, I have been exploring the possibility of using heat tracing as an 
alternative, but so far, I have not found any viable options. Any insights or 
recommendations on this matter would be greatly appreciate

Best regards,
José

[Sprinklerforum] Standpipe NFPA14 2019

2024-05-10 Thread Chris Wilson 

To all,
I have a 4 story building with 2 exit stairways I am installing a class I 
manual wet standpipe combination sprinkler system. The remote stair is on the 
interior of the building and has a rated exit passageway  on the first floor 
that is 73' long. I am placing all hose valves on the main floor landings and 
one a the exit door of the exit passage way.

I am planning on calculating 500 gpm from the remote stand pipe and 250 for the 
2nd standpipe. The exit passage way hose connection will be fed by a  2/12 
lateral pipe fed from the  4" horizontal supply to the remote standpipe as it 
pass by the exit passageway.

Do I need to include an additional 250 gpm in my calcs at the hose valve at the 
exit passageway?
