True or false, dual pressure nozzles are usually kept in the low-pressure setting?

Dual pressure nozzles are typically designed to offer flexibility by allowing the operator to select between a low-pressure and a high-pressure setting. The low-pressure setting is often preferred for a variety of firefighting operations for several important reasons.

In many scenarios, using the low-pressure setting can produce a wider flow pattern, which is particularly beneficial for applying water over a larger area quickly and effectively. This is crucial in situations such as protecting exposures, where a heavier, broader application of water is needed to mitigate heat and flames.

Furthermore, the low-pressure setting allows for better control and maneuverability of the nozzle, making it easier for the operator to manage the stream, especially in close-quarter firefighting where mobility and agility are crucial.

Although there are situations where a high-pressure setting might be necessary—such as for penetrating into a structure or reaching greater distances—the low-pressure setting is often the default choice for its versatility in various firefighting conditions. It is essential for operators to understand when to switch settings based on the context of their firefighting efforts, but the general practice is to keep dual pressure nozzles in the low-pressure position for most standard operations.
