containment line
Fire's designated boundary
A containment line is a barrier—natural or constructed—meant to stop the spread of a wildfire.
Firefighters clear vegetation, dig trenches, or use existing features like roads and rivers to create breaks the fire cannot cross.
Crews worked through the night to establish a containment line around the eastern flank.
The percentage of a fire's perimeter with completed containment lines indicates how much control firefighters have achieved.
