Question 1 of 27070

With an approved combination nozzle, low-velocity fog is produced by __________.

🔍 Key Concepts

• Combination nozzle operations on board ships • Difference between high-velocity fog and low-velocity fog • Purpose and use of fog applicators in shipboard firefighting

💭 Think About

• Think about how you would safely apply water to a fire in a confined or obstructed space without too much nozzle reaction or steam production near the firefighter. • Consider which choice actually changes the character of the water stream from a normal firehose stream into a broader, gentler fog pattern. • Ask yourself which option matches standard shipboard practice for reaching behind bulkheads, into overheads, or around corners while still using fog.

✅ Before You Answer

• Verify which device is specifically designed to create low-velocity fog rather than just changing pressure at the nozzle. • Check which option is commonly used with an approved combination nozzle in USCG/shipboard firefighting training manuals. • Eliminate any answers that only increase pressure or use a solid/straight stream, since those normally do NOT produce low-velocity fog.

Question 1 of 27070

With an approved combination nozzle, low-velocity fog is produced by __________.

the combination nozzle only when the water pressure exceeds 125 psi

putting the handle of the nozzle in the forward position

inserting an applicator in the nozzle

directing a straight stream of water against the ship's structure
