🔍 Key Concepts

• Look at the label at the top of the illustration and the word that describes this group of devices. • Think about what kind of water pattern these long, perforated tips are designed to create inside a compartment. • Recall the difference between a fog applicator and a regular smooth bore nozzle or foam applicator.

💭 Think About

• Ask yourself: Are these devices meant to shoot a solid stream of water, or to create a dispersed mist inside a space? • Consider where on a ship you would use a long, bent-tube device like this—what kind of fire situation or compartment would it be intended for? • Which option in the answers best matches a long extension that attaches to a nozzle rather than a nozzle body by itself?

✅ Before You Answer

• Verify which answer choice actually uses the word fog in a way that matches the illustration title. • Check whether an in-line foam applicator would normally have a pick-up tube or hose for foam concentrate (do you see that here?). • Confirm that a smooth bore water nozzle would have a straight, open tip rather than multiple small discharge holes like those shown.
