If firefighters cannot enter due to intense conditions, which attack can be made?

• A. Direct
• B. Indirect
• C. Defensive exterior
• D. Offensive interior

Answer: (B)

When entry is not possible because conditions are too dangerous, you stabilize the fire from outside by cooling the space and reducing the heat load before attempting interior work. This is done with an indirect attack. The idea is to apply water in a way that reaches the upper portions of the fire area or through exterior openings, cooling the hot gas layer and lowering the temperature without putting interior crews at immediate risk. By knocking down heat and fire intensity from a safer position, indirect attack buys time and creates safer conditions for a later interior attack. Direct or offensive interior methods require close, immediate access to the fire, which isn’t feasible here. A defensive exterior approach focuses on fighting from outside to prevent spread or exposure damage, but the key tactic described—reducing heat and controlling the fire from outside through indirect water application—best matches the scenario.
