What are the three groups of nozzles?

The three groups of nozzles are categorized primarily by their flow capabilities and intended applications during firefighting operations. The categorization typically includes low-volume, master-stream, and handlines.

Low-volume nozzles are designed for specific applications that require less water flow, making them suitable for situations such as brush fires or in scenarios where water conservation is necessary. Their specialized design allows firefighters to use water effectively while minimizing waste.

Master-stream nozzles are larger, high-capacity nozzles used in more severe firefighting situations. They can deliver a significant volume of water to combat large fires, often from a stationary source such as an aerial apparatus or a ground-mounted monitor. This group is essential for tackling major blazes that require extensive water delivery to gain control and mitigate the fire's spread.

Handlines refer to the smaller, more maneuverable hoses that firefighters can carry and operate. These are typically used for direct engagement with the fire at closer ranges. Handline nozzles give firefighters greater control and versatility, enabling them to adjust their water streams as needed while attacking fires from various angles and positions.

This classification helps firefighters choose the right nozzle based on the size and intensity of the fire they are facing, ensuring effective tactics are applied for successful firef
