Which of the following is a direct attack type?

• A. at the seat of the fire
• B. indirect attack
• C. from outside the compartment
• D. through ventilation shafts

Answer: (A)

Direct attack means putting the extinguishing agent right where the fire is burning—the seat of the fire—so heat is absorbed and the flames are knocked down at the source. This approach attacks the fire at its origin, which makes it the quickest and most effective way to suppress it when conditions allow access.

Attacking from outside the compartment, or through ventilation shafts, or using methods that cool or starve the fire from a distance are not direct; they influence the fire indirectly by changing airflow or heat buildup rather than applying the agent directly to the burning area.
