What operation is primarily focused on firefighting from the outside?

The primary focus of a defensive operation is to control a fire from the outside, primarily to protect exposures and prevent the spread of the fire to other structures or areas. In this strategy, firefighters work to establish defensive lines and barriers, utilizing water streams and other tools from a distance to mitigate the effects of the fire while ensuring their safety.

Defensive operations are crucial when the fire situation is too dangerous for an interior attack or when there are inadequate resources to undertake an aggressive offensive strategy. By effectively utilizing defensive techniques, firefighters can minimize property damage and maintain safety for personnel. This operation emphasizes saving lives and structures that may be threatened by the fire rather than extinguishing it directly.
