There is little flaming combustion and intensity is low under all conditions. Control is readily achieved and little or no mopping up is required. These are light surface fires, with low flames. Control is readily achieved by direct manual attack methods and with minimum forces, difficulty may be experienced on exposed, dry slopes and some light mopping up will be necessary. Flaming matches, etc. may start fires.
Fires burn on the surface with moderate flame.
Control is not difficult but direct and indirect attack with fire truck and labour should be used. Like to moderate mopping up will be necessary. Ignition can occur readily, spread may be fast in the forests though not for sustained periods. Grass fires could outstrip forces with a spread of approx. Control will be very difficult requiring indirect attack methods with major assistance necessary.
