🔍 Key Concepts

• Review the IMO Fire Control Plan symbols for fire mains and hydrants, especially the symbol used for an international shore connection. • Think about the purpose of an international shore connection: to let shore fire hoses connect to the ship’s fire main. • Compare symbols 49–54 and note which one looks like a connection fitting rather than a valve, thermometer, or detector.

💭 Think About

• Which of the numbered symbols near the bottom of Part 2 clearly shows a special fitting/coupling that could be attached between two hose systems? • Among the answer choices, can you rule out symbols that obviously represent instruments (like measuring devices) or valves, since an international shore connection is neither of those? • Look at the color background: does the international shore connection symbol appear on a solid red square like many pieces of fire equipment, or on a white background like indicators/instruments? How does that narrow your options?

✅ Before You Answer

• Verify in the illustration that the symbol you pick resembles a removable coupling/adapter, not a fixed valve or sensor. • Confirm that any symbol you eliminate is clearly a valve symbol (two triangles point‑to‑point) or a gauge/thermometer symbol (circular dial with scale). • Double‑check that the symbol you choose is used only once in the sheet and is grouped with other fire main equipment symbols, not with extinguishers or detectors.
