Steps
Read Appendix B directly on ICC's free online reading portal at codes.iccsafe.org (select the edition your jurisdiction has adopted, e.g. IFC2021P2 or IFC2024P1) — ICC provides free read access to the code text, though bulk download/redistribution is restricted
Confirm which IFC edition (and any local amendments) your specific AHJ enforces before calculating, since fire-flow tables and construction-type modifiers can change between editions
Use Section B105/Table B105.1 fire-flow calculation inputs (building area, construction type, and any listed reductions) as your working reference, but verify current table values against the live ICC page rather than an older cached PDF
If summarizing Appendix B for a client proposal, link to the ICC page rather than reproducing the full table, since the code text itself is copyrighted
Known gotchas
ICC's Digital Codes site offers free reading access to the code text itself, but that's different from a licensed, redistributable copy — don't paste full tables into deliverables without checking ICC's terms
Fire-flow requirements are frequently modified by local amendment; the base IFC Appendix B numbers may not be what your specific AHJ actually enforces
