Large-scale forest and moorland fires that last for days occur almost every year in Germany as well. They are quite risky for emergency responders, as evidenced by the many (near) accidents, casualties and losses of emergency vehicles in recent years. Often the danger for the environment or the emergency forces or the risk of spreading as well as the personnel, technical and time effort are underestimated. Almost any fire in a dry, flammable environment can grow into a large-scale operation relatively quickly under the influence of wind, surroundings, or lack of extinguishing capabilities. In part, suitable technology (vehicles and equipment) is missing. Depending on weather conditions and vegetation, there is a risk of backfiring, sometimes for weeks. For this book, the operational experience gained in many places was collected and evaluated. In this way, the typical weak points and danger points become clear. What are the consequences for the choice of equipment and operational tactics? What can the incident commander do preventively? There are clear, experience-saturated answers to this.
