Backing Fire moves in relation to wind in which direction?

• A. With the wind
• B. Against the wind
• C. Perpendicular to the wind
• D. No wind

Answer: (B)

Backings fire moves opposite to the wind. In prescribed burning, this type of fire is ignited along the fireline so that it progresses into the unburned area while the wind pushes against it. Facing the wind causes the flames to spread slowly and with lower intensity, which makes the burn easier to control and helps establish a safe, burned area ahead of the fire. If the fire were moving with the wind, that would be a head fire, which typically spreads faster and is harder to control. Perpendicular spread would be a flanking fire, and no wind changes the dynamics but doesn’t bias the fire toward one direction.
