Working definition

A natural or constructed barrier intended to stop or check fire spread or provide a line from which crews can work.

In plain language

A firebreak removes or interrupts burnable material, but its effectiveness depends on width, fuels, wind, flame geometry and spotting.

Why it matters

Calling a strip of cleared ground fireproof creates false confidence. Embers and intense flames can cross barriers.
