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.
