Which statement best describes direct attack?

• A. Water is applied directly onto the burning fuels using a solid or straight stream
• B. Water is applied to the structure to cool the exterior
• C. Water is used to wash smoke from windows
• D. Water is used only after ventilation is complete

Answer: (A)

Direct attack targets the fire at its source by applying water directly to the burning fuels to absorb heat and cool the fuel so the flames are knocked down. This approach relies on getting water where the fuel is actually burning, which quickly lowers the temperature of the fire and helps prevent reignition. A solid or straight stream is used because it can reach the base of the fire and penetrate into the burning material, delivering cooling power directly to the seat of the flames. Cooling the exterior of the structure describes an exposure-control tactic, not attacking the flames themselves. Washing smoke from windows relates to ventilation or smoke management, not extinguishing the fire. Using water after ventilation describes a later phase that isn’t applying water directly to the burning fuels to suppress the fire immediately.
