Question 1 of 27070

To operate a CO₂ fire extinguisher equipped with a squeeze grip handle, you are to remove the locking pin and __________.

🔍 Key Concepts

• Basic operation of portable CO₂ extinguishers (how squeeze-grip types are activated) • Difference between old-style wheel valves and modern squeeze-grip handles • Safe handling of CO₂ (cool discharge horn, high pressure, directed jet)

💭 Think About

• Think about what the hand you keep on the carrying handle is doing, and what the other hand must do to start discharge on a squeeze-grip type. • Which actions in the choices sound like they would be used on an older, wheel‑type valve rather than a modern squeeze‑grip? • Would inverting a CO₂ extinguisher be normal, recommended, or necessary for it to work?

✅ Before You Answer

• Confirm how a squeeze‑grip handle is normally held: one fixed part, one moving part. • Eliminate any options that refer to valve wheels or discs, since those belong to a different style of extinguisher. • Ask yourself which motion (up/down or rotate) would most likely open a spring‑loaded valve in a hand‑held grip.
