What is the term for the practice of controlling the size of a fire?

The term for the practice of controlling the size of a fire is "fire control." This practice involves a range of procedures and strategies aimed at managing fire outbreaks to prevent them from spreading beyond their initial boundaries. Fire control focuses on strategies such as directing fire suppression efforts, establishing fire lines, and utilizing firefighting resources effectively to contain the fire and minimize damage.

While other options like fire prevention, fire restriction, and fire suppression touch on related concepts, they do not specifically define the active management of fire size in the same way. Fire prevention involves measures taken to prevent fires from starting in the first place, fire restriction can refer to policies aimed at limiting fire activity, and fire suppression generally describes the overall effort to extinguish a fire rather than the ongoing control once a fire has ignited. Thus, fire control is the most accurate term when discussing the active management and containment of fire size.
