fire perimeter
Flame containment line
A fire perimeter is the outer boundary of a wildfire—the entire edge where burning or burned area meets unburned vegetation.
Firefighters establish and monitor the perimeter to track a fire's spread and plan containment strategies: The fire perimeter expanded to twelve miles overnight.
A fire is "contained" when crews have established control lines around the entire perimeter.
