If a firefighting situation calls for low-velocity fog which action would you take?

🔍 Key Concepts

• All-purpose fire nozzle operation (lever positions vs. stream types) • Difference between solid stream, high-velocity fog, and low-velocity fog • When a fog applicator is needed versus just adjusting the nozzle pattern

💭 Think About

• Think about what specifically changes the water pattern from a straight stream to a wide, gentle fog: is it pump pressure, nozzle position, or extra equipment? • For an all-purpose nozzle that already has a fog setting, what does moving the lever forward or back usually do to the stream? • Under what circumstance would you actually need to add a separate low-velocity fog applicator rather than just adjust the nozzle you already have?

✅ Before You Answer

• Identify how lever position on a standard all-purpose nozzle typically affects stream pattern (straight stream vs. fog). • Decide whether pump pressure or nozzle setting is the primary control for getting low-velocity fog. • Consider whether attaching a fog applicator is necessary if your nozzle can already produce low-velocity fog by itself.
