What defines a Handline Indirect Attack?

A Handline Indirect Attack is defined as a defensive approach away from the fire edge. This technique involves creating a fireline that is situated at a distance from the fire’s active front, allowing firefighters to manage the fire's spread while maintaining a certain level of safety. The focus is on taking advantage of natural barriers or creating lines of firebreaks that will guide the fire in a more manageable direction or contain it effectively.

This method contrasts with more direct techniques where firefighters engage directly with the fire front, which can be more hazardous and complicated. By establishing lines away from the fire's edge, crews can also utilize the environment—such as terrain features or burn scars from previous fires—to help control the fire's movement without exposing themselves to immediate danger.

The other choices pertain to either different tactical approaches or support methods. For instance, directly attacking the fire's path indicates confronting the fire head-on, while evacuation methods focus on ensuring personnel safety rather than engaging with the fire's progression. Aerial support, while a critical aspect of firefighting strategies, doesn't specifically define the indirect attack method, which centers on ground-level operations.
