What angle on the vari nozzle is preferred for an indirect attack to allow for quick re-entry?

• A. Narrow angle
• B. Medium angle
• C. Steep angle
• D. Wide angle

Answer: (D)

Pushing the nozzle to a wide dispersion pattern is ideal for an indirect attack because it blankets a large area with water, rapidly absorbing heat and producing steam that cools the environment. This broad spray lowers the radiant heat and helps push down the flame zone, creating a safer, clearer path for quick re-entry. A wide angle covers ceilings and upper walls, which is where heat and fire spread first during an indirect attack, so you can establish a cooler, more stable environment before entering. In contrast, a narrow or steep pattern focuses water on a smaller area or travels farther with higher velocity, which is less effective for cooling a large space quickly and doesn’t facilitate as rapid a re-entry.
