🔍 Key Concepts

• Semi-portable CO₂ systems typically discharge through a hose and horn assembly, not through foam nozzles or cylinder valves directly held in the hand • Focus on the shape of the handle and trigger in the illustration – it looks like a pistol‑grip with a squeeze lever that can be latched • Think about which option would logically need a latch to keep the flow continuous without holding the trigger

💭 Think About

• Does the item in the picture look more like a hand nozzle used on a hose, or like a valve directly on a cylinder bottle? Why? • Which of the listed devices would most benefit from a latch that keeps the trigger in the open position during an extended CO₂ discharge? • Compare the drawing to what you know about all‑purpose fire nozzles versus CO₂ discharge horns – which has this kind of trigger handle?

✅ Before You Answer

• Be sure the device you pick is something that would be found on a semi‑portable CO₂ system hose assembly • Confirm that the latch shown would logically be used to hold a squeeze handle open, not to set a stream pattern or operate a foam nozzle • Eliminate any options that describe equipment more typical of water or foam fire streams, rather than CO₂ discharge horns
