🔍 Key Concepts

• Look closely at all CO₂-related symbols in the table, not just one • Distinguish between a symbol for a CO₂ nozzle/discharge point and a symbol for a room or bank of cylinders • Fire control plans often use a special icon when many cylinders are grouped together in a dedicated space

💭 Think About

• Which numbered symbol shows a space or bank of multiple CO₂ cylinders stored together, rather than a single extinguisher or nozzle? • Compare the symbols near 7, 8, 9, and 42: which one would most logically mark a CO₂ bottle room on a deck plan where all the fixed-system cylinders are kept? • If you were tracing the CO₂ system on a ship, which symbol would you expect to find only once or twice on the plan, marking the storage room, instead of at each discharge location?

✅ Before You Answer

• Verify which candidate symbol clearly shows multiple CO₂ cylinders grouped in one place • Check that the chosen symbol does not look like a portable extinguisher or discharge head/nozzle • Confirm that the symbol you pick is something you would reasonably use to label a room or space on the fire control plan, not a single piece of equipment
