🔍 Key Concepts

• Operation of an all-purpose (combination) firefighting nozzle on standard marine fire hoses • Relationship between handle position and type of stream: fog, narrow fog, and solid/straight stream • How nozzle settings are designed for maximum reach vs. maximum coverage

💭 Think About

• Think about which handle position on a combination nozzle is normally used when you want the longest reach to hit a fire that is far away • Recall how the water pattern changes as you move the handle from fully forward to fully back: which end of that range gives you a tight, concentrated stream instead of a wide spray? • Consider how firefighters would set the nozzle if they needed to punch water deep into a compartment rather than cool the air with a wide fog pattern

✅ Before You Answer

• Make sure you know which handle position corresponds to full straight/solid stream on a standard all-purpose nozzle used in USCG training diagrams • Verify in your reference manual which direction (forward vs. back) gives wide-angle fog and which gives straight stream • Before choosing, mentally picture the nozzle markings (FOG – NARROW FOG – STRAIGHT STREAM) and where the handle sits for STRAIGHT STREAM
