Which statement best describes the use of a smoothbore nozzle?

• A. When longer reach and higher solid stream are needed
• B. When a broader pattern for cooling and visibility is required
• C. When a small, enclosed space is involved
• D. When rapid cooling with a wide fog pattern is needed

Answer: (A)

Smoothbore nozzles produce a solid, high-velocity stream that travels farther and with more penetrating power than a wide, foggy spray. This makes them ideal when you need reach and a concentrated jet to hit the fire from a distance or through openings, allowing water to reach the seat of the fire efficiently. They’re less suited for interior cooling or for quickly improving visibility in smoke, because they don’t create a broad, cooling pattern like a fog nozzle does. So the statement describing longer reach and a higher solid stream best captures when a smoothbore nozzle is used.
