In what scenario would a water curtain nozzle be most beneficial?

A water curtain nozzle is specifically designed to create a barrier against fire by discharging a fine mist of water, effectively cooling the air and reducing the temperature in the area it covers. This mist can block heat radiation, providing a protective shield that helps prevent flames from spreading or reaching nearby combustibles.

This application is particularly useful in scenarios such as protecting exposure buildings, flammable materials, or preventing fire spread during structural firefighting operations. The use of a water curtain is not primarily for direct extinguishing of flames, which involves applying water directly onto the fire itself. It does not focus on high-pressure water delivery, nor is it intended to direct water away from an area without serving as a barrier; rather, the curtain is all about creating a defensive line against the advancing heat and flames.
