n. A linear path where fuel has been cleared to mineral soil as a defensive measure before a wildland fire occurs.
A firebreak is intended to serve as a permanent barrier against fire. It is usually constructed as part of a strategic plan to protect people, resources, and/or structures. A firebreak differs from a fuelbreak in that all fuel is removed from a firebreak, whereas some fuel is left in a fuelbreak. A firebreak usually requires maintenance to keep the area fuel-free. Roads can often serve a firebreak function in addition to a transportation function.
