🔍 Key Concepts

• Positions of the all-purpose nozzle control handle (horizontal vs. vertical) • Difference between straight stream, high-velocity fog, and low-velocity fog • How applicators (bent tip, wide-angle) change the nozzle’s pattern

💭 Think About

• Think about what pattern firefighters usually want for maximum reach when using the nozzle with no applicator attached. • Recall which setting on the nozzle handle is normally used to completely stop the flow of water. • Consider which fog pattern (high- or low-velocity) is typically associated with extra attachments or applicators rather than the bare nozzle.

✅ Before You Answer

• Confirm what the vertical handle position means on a standard all-purpose nozzle (open vs. shut). • Verify which stream type is produced without any applicator attached. • Make sure you distinguish between fog patterns and a solid/straight stream in terms of reach and droplet size.
