Needed Fire Flow

Needed fire flow is the amount of water that should be available for providing fire protection at selected locations throughout a community. ISO has prepared a guide for estimating needed fire flow. The publication is only a guide and requires knowledge and experience in fire-protection engineering for its effective application.

You can download a copy of the Guide for Determination of Needed Fire Flow. The document is a PDF file of approximately 90kB. You can view or print the file with a free Adobe® Acrobat® Reader.

Customized reports
For information about your own community's public fire protection, a customized PPCTM report is available by mail from ISO. The report includes a list of the needed fire flows for all the commercial occupancies ISO has on file for your community, as well as details of the latest review of your community's fire protection services (that is, your PPC grading). The report is available only to your community's fire chief or chief administrative official. ISO does not charge communities for these reports.
