The action of setting a fire along the inner edge of a fire control line to consume the fuel between the line and the fire's edge is called a _____.

• A. Backfire
• B. Burnout
• C. Firebreak
• D. Fire out

Answer: (D)

Burnout is the controlled ignition of fuels inside a fire control line, letting them burn toward the fire edge so the area between the line and the fire becomes fuel-free. By starting the burn on the inner edge, crews create a blackened, protected zone that the main fire can’t cross, increasing the chances that the line will hold. This technique is a common part of building and reinforcing firelines, used to ensure there’s no continuous fuel for the fire to sweep through.

Backfiring is a related tactic but involves igniting fuels ahead of the fire to influence its direction, not the same as burning inside the line to remove fuel. The firebreak is the physical barrier itself, not the action of burning fuels. Extinguishing a fire entirely would be described as putting it out, not performing a burnout.
