What is the objective of an indirect fire attack?

• A. Directly extinguish flames at the source
• B. Create a thermal barrier to prevent heat transfer
• C. Quickly remove as much heat as possible
• D. Ventilate the structure to the atmosphere

Answer: (C)

Indirect fire attack is about cooling the space to curb the fire’s heat. The main objective is to remove heat from the environment as quickly as possible. By applying water from the ceiling or in a high, wide pattern, the water absorbs a lot of heat as it converts to steam, lowering the temperature of the hot gases and surfaces. That rapid cooling slows the heat release rate, helps prevent flashover, and creates safer conditions for occupants and firefighters to operate. Directly extinguishing the flames at their source is a different approach, while ventilation and barriers might be used in tandem but are not the primary aim of an indirect attack.
