Inside and Outside Hose Allowance
Inside and Outside Hose Allowance
(OP)
As per NFPA, the total inside and outside hose allowance for extra hazard group is 500 gpm. My understanding is this allowance is only for the inside and outside hoses which excludes any fire hydrant allowance (class-1 standpipe). For fire hydrants, we need to add additional allowance of 500gpm.
I would like to know the above considerations are in compliance with NFPA standards.

Thanks Travis Mack

The hydrants also have to meet site fire flow requirements. These are separate from the fire sprinkler system and hose allowances.

RE: Inside and Outside Hose Allowance
As you have said that Maximum required hose allowance is 500 gpm for both inside and outside hoses in EH. If I am not providing any outside hose, can I deduct 400 gpm and use only 100 gpm as inside hose allowance in the calculations.
