What should personnel evaluate when a fire shows significant risk?

When a fire presents a significant risk, evaluating structural integrity and fire behavior is crucial for ensuring the safety of both personnel and civilians. Understanding how the fire is behaving—such as its intensity, spread, and the materials involved—helps personnel assess potential hazards like flashover, backdraft, or structural failure.

Furthermore, analyzing the structural integrity involves examining the building’s condition, identifying weak points, and determining if it is safe for firefighting operations. If the structure is compromised, it may not be safe for firefighters to enter, which can significantly influence tactical decisions. This assessment not only allows for appropriate actions to mitigate risks effectively but also protects the lives of those involved in firefighting operations and the public.
