    Description

    The fire characteristics chart is proposed as a graphical method ofpresenting 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 (NFDRS) 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 potential application.
