🔍 Key Concepts

• Compare the CO₂-related symbols in this illustration, especially numbers (7), (8), and (9) • Think about the difference between equipment pieces (like horns or bottles) and areas/spaces being protected • Recall that fire control plans use different symbols for the agent source, the discharge device, and the space covered

💭 Think About

• What visual clues in symbol (7) suggest it represents an entire area or volume, rather than a single piece of hardware? • How does the shape and the direction of the small marks under (7) compare to common ways of showing a spray or flooding pattern? • Which other numbered symbol in the row looks most like a physical CO₂ horn, and how does that help you eliminate some choices?

✅ Before You Answer

• Identify whether symbol (7) looks more like a room/space outline or a mechanical device • Compare symbol (7) directly to symbol (8) and decide which one better matches a horn/nozzle • Before choosing, be sure your option matches the idea of system coverage vs. individual component (horn, bottle, release station, or alarm)
