A method of suppression in which the control line is located some considerable distance away from the fire’s active edge. Generally done in the case of a fast-spreading or high-intensity fire and to utilize natural or constructed firebreaks or fuel breaks and favorable breaks in the topography.
What is the difference between direct and indirect fire attack?
Parts of direct fire attack include: digging a fire line directly around the flames and pulling burned fuel into the black; using water; smothering; and removing an element from the fire triangle. Indirect fire attack is used when you can’t safely engage directly, because the fire rate of spread is significant.
What is a direct fire attack?
Any treatment applied directly to burning fuel such as wetting, smothering, or chemically quenching the fire or by physically separating the burning from unburned fuel.
