What is a fireline?

• A. A line drawn to designate property boundaries
• B. A cleared strip of land with reduced fuels to slow or stop fire
• C. A line of fire used to direct fire
• D. A water supply line

Answer: (B)

Fireline is a cleared strip of land where fuels are reduced or removed to slow or stop the spread of fire. By interrupting the continuity of flammable material, the fire struggles to advance across the line, and the area on the other side becomes a safer place for crews to work from or to anchor the fire. The line is often brought down to mineral soil so radiant heat and embers don’t ignite fuels beneath. Firelines can be created by hand tools, machine dozers, or by mowing and removing brush, and their width is adjusted based on slope, wind, and fuel conditions to ensure the fire can be contained. The other ideas don’t fit because marking property boundaries, directing fire with a line of fire, or running a water supply line serve different purposes and are not intended as barriers to stop a wildland fire.
