Fire Controllability Guide

If started they spread very slowly and may go out without suppression forces. There is little flaming combustion and intensity is low. Control is readily achieved and little or no mop up is required.

Ignition may take place near prolonged heat sources. Speed is slow in forests, moderate in open areas. Light surface fires with low flames. Control is readily achieved with direct manual attack with minimum forces. Steep, exposed slopes may require light mop up.

Open flame will start fires. Mature grasslands and forest litter will burn readily. Spread is moderate in forests and fast in exposed areas. Fires burn on surface with moderate flame heights. Fight fires with direct attack and all available resources including aircraft. Light to moderate mop up.

Ignition can occur readily with fast spread in forests. Grass fire behaviour will be extreme. Fires will be very hot with crowning and short to medium spotting. Direct attack on the head may not be possible requiring indirect methods on flanks. All available resources must be used with extended mop up. Beware of wind change!!!

Ignition can occur from sparks. Fires will be extremely hot with fast rate of spread. Control may not be possible during day due to long range spotting and crowning. Suppression forces should limit efforts to limiting lateral spread. Damage potential total. All available resources must be used with extended mop up and careful attention to areas that can flare up. Beware of wind change!!!
