With the current wildfire season in full swing, Canadians are being regularly informed about the status of various fires – whether they are “out of control,” “held,” or “contained.” Despite this, understanding the implications of each stage may not always be straightforward.
Across most provinces, wildfires are categorized similarly, albeit with slight variations in terminology. Here’s a brief overview of what each stage signifies:
**Out of control**: This designation indicates a wildfire that is unresponsive to suppression efforts and is anticipated to expand without a defined perimeter. While the term may sound alarming, it simply implies expected growth rather than chaotic conditions. Operational strategies at this stage involve aggressive suppression tactics like establishing control lines, conducting burn-offs, and utilizing water, foam, or retardant.
**Being held, contained, partially controlled**: At this phase, firefighters have set up a boundary or perimeter around the fire, whether naturally occurring or created by fire crews, to prevent it from spreading beyond that limit. Although flames within the perimeter may burn intensely and the fire could still increase in size, the established boundary is expected to contain it.
**Under control**: A wildfire is considered under control when it is completely contained within a set perimeter, no longer spreading, and moving towards extinction. Continuous monitoring and post-weather checks are conducted to ensure no reignition occurs. While there may be residual smoke or hot spots, active flames are typically extinguished.
**Out, extinguished**: This stage marks the conclusion of firefighting efforts, with successful suppression and the absence of hot spots. Certainty is crucial in declaring a wildfire as extinguished, as any potential flare-ups must be ruled out.
Even after a fire is extinguished, significant recovery efforts are essential, including replanting vegetation and restoring ecosystems. This phase underscores the ongoing commitment required post-firefighting to rehabilitate affected areas.
Wildfires can remain at various stages for extended periods, necessitating sustained management and vigilance to address any potential resurgence.
