An abandoned building is fully involved in fire. Which type of operation is appropriate?

In the scenario of an abandoned building fully involved in fire, a defensive operation is the most appropriate choice. Defensive operations aim to protect exposures, prevent the fire from spreading beyond the structure involved, and ensure firefighter safety.

Given that the building is abandoned, there is no risk to occupants or property inside, making it less critical to engage in direct fire attack, which typically involves entering the structure to extinguish the fire directly. Instead, a defensive approach allows firefighters to work from a safe distance, utilizing aerial devices, master streams, or other equipment to control the fire without entering the hazardous environment. This strategy focuses on protecting adjacent structures or areas that could be threatened by the fire's heat and flames.

In summary, the defensive operation prioritizes safety and resource management while addressing the situation effectively, making it the most suitable choice for an abandoned structure fully involved in fire.
