🔍 Key Concepts

• All-purpose fire hose nozzle positions and how they control flow type • Relationship between handle position and internal water path (open/closed/deflector engaged) • Difference between a solid stream, spray/fog, and no flow in practical firefighting use

💭 Think About

• Look at how the handle moves from position A to B to C. What does each progressive movement likely do to the water path inside the nozzle? • On most marine all-purpose nozzles, when does the water strike the deflector plate to create fog/spray, and when does it pass straight through? • Which handle position in the illustration appears most likely to have the waterway completely shut off?

✅ Before You Answer

• Compare all three positions A, B, and C and decide which one must represent no flow – eliminate that first. • Think about where the deflector or fog tip would be when the handle is fully forward or fully back – which orientation would allow a straight, solid stream? • Ask yourself: in position C, does the handle look more like an "open" or "closed" position compared to A and B? Choose the flow type that matches that idea.
