🔍 Key Concepts

• Difference between extinguishing medium discharge points (nozzles) and storage locations (bottle rooms) on fire control plans • How a main battery of Halon 1301 bottles would be shown compared to individual or reserve cylinders • Visual distinctions among the symbols labeled HALON or with an H in illustration D039SA

💭 Think About

• Look at each symbol option number and decide which ones show where Halon is released into a space versus where Halon bottles are stored together in a room. • Among the symbols related to Halon, which one clearly looks like a large grouped bank of bottles rather than a single bottle, nozzle, or generic Halon sign? • Consider what a "main battery" of bottles would look like on board a ship and match that to the symbol that best represents a dedicated Halon bottle room.

✅ Before You Answer

• Verify which symbol shows multiple Halon 1301 cylinders racked together (a bank), not just one or two. • Confirm that you are not choosing a symbol that represents a discharge nozzle or a protected space instead of the bottle room. • Double‑check that the symbol you pick includes a clear indication of Halon 1301 bottles themselves, not just the word HALON over a spray pattern.
