Detailed explanation-1: -But how does the technique actually work? A back fire is a fire that is deliberately initiated in front of an active fire front, usually a forest fire, grass fire, or some other type of wildfire. The backfire consumes some of the combustible material and creates a fire belt that the wildfire has difficulty crossing.
Detailed explanation-2: -A backburn is a fire lit close to the edge of an active bushfire, which burns out the fuel between the bushfire and an established control line. The removal of fuel halts the fire’s spread, providing suitable conditions for firefighters to finish suppressing the fire.
Detailed explanation-3: –overfilling, deflagration or ground throwing of the edge of the creeping fire; -fire suppression with water or solutions of fire suppression chemicals; -laying of mineralized strips and ditches; -clean burn [6, 8, 9].
