Coffee Break Training: Access and Water Supplies: Fire Flow Formulas: Part 19: 'International Fire Code' Fire Flow Requirement Sample   [open pdf - 557KB]

"The IFC [International Fire Code] describes fire flow as the rate of a water supply at a pressure of 20 pounds per square inch (138 kilopascals) that is available for firefighting. The IFC method employs a table that lists the minimum flow based on the 'International Building Code®' construction type and size of the structure, or what is called the 'fire flow calculation area.' The fire flow calculation area is the sum of all floor area between firewalls with no openings or, in fire-resistive construction, the sum of the area of the three largest successive floors. IFC Appendix B also allows fire flow reductions between 50 percent and 75 percent if the structure is protected by automatic sprinklers in accordance with National Fire Protection Association (NFPA) 13, 'Standard for the Installation of Sprinkler System's or NFPA 13R, 'Standard for the Installation of Sprinkler Systems in Low-Rise Residential Occupancies'."
