Fire protection nozzles serve a critical role in delivering water, foam, or other fire-retardant liquids to areas where a fire has broken out, with the goal of extinguishing it. This can be achieved through two primary approaches: either by dousing the fire with large volumes of liquid or by spraying fine mists that evaporate quickly, displacing oxygen and suffocating the fire. These approaches require different types of nozzles—specialized deluge nozzles are typically used for high-volume systems, while misting nozzles are designed for fog-type applications.
In some scenarios, nozzles can also be used proactively to reduce the risk of a fire starting. This is often achieved by lightly wetting the area to raise the ignition threshold. More subtly, nozzles can increase air humidity to minimize static buildup in environments where sparking could pose a fire hazard. Additionally, they can be employed to reduce dust levels in spaces where dust accumulation could lead to fire or explosion risks.
