A fire is said to be controlled when the Control Line is complete and the fire cannot escape. This means that all measures have been taken to ensure that the fire will not spread beyond a designated area, indicating that the firefighters have successfully surrounded the fire with an unburnable barrier. Achieving this condition typically involves the absence of any active burning and the establishment of lines that can effectively contain the fire's advance. This concept is crucial in wildland firefighting, as achieving a controlled status allows firefighters to focus on extinguishment and securing the perimeter without the risk of the fire re-igniting or breaking out.

The other conditions either indicate that the fire is still active or only partially contained, which does not reflect a controlled status. For instance, if flames are still visible or only embers remain, it suggests that the fire is still burning in some capacity and may pose a risk of escape. Therefore, the definition of a controlled fire encompasses both the establishment of secure control lines and the assurance that the fire will not escape those lines.
