🔍 Key Concepts

• All-purpose nozzle components and how they connect • What a bayonet catch (bayonet coupling) looks like and how it secures attachments • Differences between foam equipment and fog tips on fire hoses

💭 Think About

• Which one of these four items is normally a separate attachment that must be held firmly in place during operation? • Which item would most likely need a quick-connect/quick-release locking device so it doesn’t blow off under pressure? • Think about which devices are usually threaded on, and which are more likely to use a latch-type coupling.

✅ Before You Answer

• Identify which choice is typically at the discharge end of the nozzle body itself • Consider which device is designed to be easily interchangeable during firefighting operations • Ask: which part is most critical to stay locked in position under high pressure and flow conditions?
