Which of the following is NOT a direct fire fighting method?

• A. Direct at seat
• B. Direct at access
• C. Fog attack
• D. Indirect ventilation

Answer: (D)

Direct fire fighting methods focus on applying the extinguishing agent where the fire is burning to cool and suppress it at the source. Aimed water directly on the seat of the fire или a direct attack from the opening to reach the flames both fit this approach, as does using a fog pattern to deliver water straight into the fire to absorb heat and push back the flames. Indirect ventilation, by contrast, is about changing the airflow around the fire to control heat and smoke, not about applying water or foam to extinguish the flames itself. It helps create safer conditions and supports other tactics, but it isn’t a direct method of fighting the fire. So indirect ventilation is not a direct fire fighting method.
