Firefighter 1C Wildland Practice Exam

During which phase of a fire does spotting typically occur?

1. Ignition

2. Growth

3. Fully Developed

4. Decay

The correct answer is: Growth

Spotting typically occurs during the growth phase of a fire. This phase is characterized by the rapid spread of the fire as it gains intensity and begins to consume available fuel more efficiently. As the fire grows, it generates heat, which can create firebrands—small burning embers that can be lifted by the wind and carried away from the main fire area. These firebrands have the potential to start new fires, or "spot fires," in areas ahead of the advancing flame front. This phenomenon can significantly increase the complexity and danger of wildland fire behavior, as it can lead to the fire spreading beyond control boundaries and impacting areas that are not directly adjacent to the main fire. In contrast, during the ignition phase, the fire is just starting and has not yet developed the intensity necessary to produce significant spotting. In the fully developed phase, the fire is at its peak intensity, and while it may still produce spotting, the primary concern during this phase is often the established fire perimeter and its direct control. The decay phase involves a reduction in the fire's energy and intensity, which typically leads to a decrease in spotting activity as the fire burns out.
