What is a significant advantage of using fog nozzles?

A significant advantage of using fog nozzles is greater heat absorption. Fog nozzles create a fine mist of water droplets, which increases the surface area of the water. This allows the water to absorb heat more efficiently, leading to quicker cooling and suppression of fire. The transformed water vapor in the fog also displaces oxygen around the fire, which is crucial in reducing the combustion process.

While the other options present valid attributes of firefighting nozzles, they do not capture the unique benefits fog nozzles provide in terms of heat absorption and fire suppression efficiency. Higher water flow rates are typically a feature of smooth bore or adjustable nozzles, while better penetration into structures is associated with solid stream nozzles. Reduced water usage may be a benefit of more efficient application methods in some cases, but it does not specifically highlight the advantages of fog nozzles, which are particularly designed to maximize heat absorption.
