If fuels are left in the line area, how does this affect fire control?

• A. It reduces barrier effectiveness and increases spread risk.
• B. It improves barrier effectiveness.
• C. It has no impact.
• D. It makes the operation easier.

Answer: (A)

Fuels left in the line area create a continuous fuel bed that the fire can use, so the barrier’s ability to stop the fire is compromised and the fire can spread more easily along or across the line. Clearing fuels down to mineral soil in the line area reduces heat transfer and prevents ignition of fuels right at the line, helping maintain the barrier and lowering the risk of the fire crossing or riding the edge. Leaving fuels would not improve the barrier, and it would not make the operation easier; it would actually make control harder.
