Good news is emerging from the fire lines, but it requires a specific vocabulary to decipher. After nearly a week of relentless battle, the massive wildfire in Gironde was described as “contained within its perimeter” on Thursday evening, yet it remains active in pockets, preventing officials from declaring it “fixed.”
“There is still hope, we are working for it, but I cannot guarantee that the fire will be fixed this weekend,” stated Éric Pitault, a communications officer for the departmental fire and rescue service (Sdis 33), on Friday, July 31. While caution remains essential, optimism is also growing in the neighboring Landes department, where a fire near Biscarrosse is now “mastered,” according to prefect Gilles Clavreul.“Fixed,” “mastered,” “circumscribed”… The vocabulary employed by firefighters and authorities to describe forest fires is highly specific. As conditions begin to show improvement, understanding these technical terms is key to grasping the true progression of a blaze.
Fire is ‘Fixed’
This is the first critical designation used by firefighters. A fire is considered fixed when the flames are no longer advancing, “but it is not yet under control,” according to wildfire prevention resources. Crucially, the inferno can still regain intensity.
The fire can remain active and spread if conditions change, such as an increase in wind or a drop in humidity. This means the situation is delicate and requires constant vigilance to prevent a resurgence.
Fire is ‘Circumscribed’
A fire is termed circumscribed when firefighters have successfully halted the spread of the flames “by creating a fire line around the wildfire.” This tactical achievement effectively prevents the fire from expanding its footprint. However, the danger is far from over, as the fire can still be actively burning inside the contained zone, consuming unburnt fuel within the perimeter.
Fire is ‘Mastered’
A fire can be described as mastered when “firefighters have managed to extinguish most of the flames and the fire is under control.” This does not mean the fire is completely out. Hot spots can persist in the affected area, posing a significant risk of re-ignition. Two other unofficial terms are also used to describe this precarious phase: “stabilized” and “contained.”
Marc Vermeulen, the director of Sdis de Gironde, humorously acknowledged the linguistic flexibility required during such massive operations. “I’m going to receive text messages from firefighters telling me that term isn’t used,” he joked during a press conference about the word “stabilized.” “Indeed, it’s not standard. But when you are on projects of this scale, you have to find a term for when the fire is no longer progressing but is not yet ‘fixed’.” He emphasized that their current action is to “contain [this fire] within the envelope, continue to cool it, to treat it, precisely so we can move it to ‘fixed’ status,” noting the persistent “hot spots” and “smoldering fumes that still appear quite regularly due to the temperature conditions.”
Fire is ‘Drowned’
To signify that a wildfire is completely extinguished, firefighters use the definitive term “drowned.” This indicates that no hot spots or embers remain, and the risk of re-ignition has been eliminated. It is the final stage in a long and arduous battle. It is important to note that every wildfire is different, and the time required to transition from one state to the next can vary greatly depending on the size and complexity of the fire.
