Add Needed Fire Flow

Needed fire flow is an estimate of the amount of water that should be available for a specific occupancy. The required fire flow GPM figure is calculated based on a formula developed by ISO ("Guide for Determination of Needed Fire Flow", Edition 10-2001, © 2001 ISO PROPERTIES, INC., 2001). Additional information about needed fire flow and the role of needed fire flow in ISO's Public Protection Classification (PPC) Program are available at http://www.isomitigation.com.
