What is a characteristic of a friendly fire?

A characteristic of friendly fire is that it is contained in the place intended for it. This term typically refers to a situation where a fire, often in a controlled setting, such as a fireplace or a designated burn area, burns as planned without inadvertently spreading beyond its boundaries. This controlled aspect is crucial for maintaining safety and preventing unintended damage.

In contrast, other options describe scenarios where fires pose more risks. For instance, if a fire spreads beyond its intended area, it indicates a loss of control, which is contrary to the concept of friendly fire. Similarly, if a fire occurs unexpectedly, it suggests a lack of planning or forethought, which does not align with the idea of friendly fire being controlled and planned. Finally, while significant property damage can occur as a result of uncontrolled fires, friendly fire is characterized by its containment and management, making it a safer and more predictable situation.
