Which of the following is associated with the rear/heel of the fire?

The rear or heel of a fire is associated with areas that are closer to the fire's origin. These sections typically exhibit less vigorous burning compared to the more active flames found at the leading edge of the fire or its flanks. The nature of the fire's behavior at the rear often involves lower intensity flames, which can be influenced by factors such as fuel availability, weather conditions, and topography.

In the context of firefighting, understanding the behavior of fires at their rear is crucial for strategic planning and suppression tactics. By recognizing that the rear is often a less aggressive part of the fire, firefighters can prioritize their interventions effectively, targeting the more hazardous areas first while remaining aware of how conditions may change in the rear section.
