A fireline is designed to contain the leading edge of a wildland fire by completely removing fuel in the path of the fire.  A fireline can be created using hand tools or with mechanized equipment. The width of a fire line can range from 1 ft to more than 20 ft. The rate of fireline construction depends on the fuel types encountered (grass, litter, logs, and so on) and the steepness of the terrain. On large wildfires, a fireline may be constructed at some distance from the leading edge of a fire, and a backfire or burnout may be ignited from the edge of the fireline back towards the leading edge of the fire to remove fuel as the wildfire approaches the fireline.
