We have a 100 ft high rise residential bldg. with major renovations. There are two existing 4" standpipes. The building will be retrofitted with a sprinkler system per NFPA 13. From NFPA 14 2003,can 5.4.1.3 be used to not require a fire pump to supply the standpipe 100 psi pressure since this existing 80 year old bldg is being sprinklered? Is the fire pump required to supply 750 gpm with 500 gpm at 100psi at the most remote standpipe? Art Tiroly ATCO Fire Protection
Roland Huggins wrote excellent question. I put my money on Steve's answer. The NFPA committees that I am on (or familiar with) are aggressively moving away from encouraging occupants to use a hose (which correlates nicely with OSHA requirements).
