Description

The fire characteristics chart is proposed as a graphical method of presenting two primary characteristics of fire behavior: spread rate and intensity. Its primary use is communicating and interpreting either site-specific predictions of fire behavior or National Fire-Danger Rating System (NF3RS) indexes and components. Rate of spread, heat per unit area, flame length, and fireline intensity are plotted on a fire behavior chart. Spread component, energy release component, and burning index are plotted on an NFDRS chart. Specific examples illustrate use of a fire characteristics chart in conjunction with fire prescriptions, fire behavior forecasts, fire .management plans, and briefings. The equations used in creating the charts are given; and a method of obtaining heat per unit area from fire behavior nomograms is illustrated.
