Barrière naturelle ou artificielle existante, qui aura pour effet d'enrayer ou de retarder la propagation d'un feu.
- coupe-feu n. m.
An existing barrier or change in fuel type (to one that is less flammable than that surrounding it), or a wide strip of land on which the native vegetation has been modified or cleared (fireguard), that acts as a buffer to fire spread so that fires burning into them can be more readily controlled.
Often selected or constructed to protect a high value area from fire. In the event of fire, may serve as a control line from which to carry out suppressive operations.
