If available, which nozzle should be used to get under the hood, fender, or wheel well?

• A. Fog nozzle
• B. Piercing nozzle
• C. Straight stream nozzle
• D. Rotary nozzle

Answer: (B)

When fighting a vehicle fire, the goal is to get water directly to the flames that are trapped in tight spaces like under the hood, inside fenders, or in wheel wells. A piercing nozzle is designed to push a water jet through small openings or through thin barriers, allowing you to reach the core of the fire in the engine compartment without having to remove panels or open the hood first. This direct access means rapid cooling and quicker knockdown in confined, obstructed areas. Other nozzles spread water differently and may not reach or penetrate into those cramped spaces as effectively, making the piercing nozzle the best choice when it’s available.
