🔍 Key Concepts
• Look closely at the four numbered symbols 13, 16, 15, and 17 and decide which ones show a piece of equipment (nozzle, monitor, valve, connection) versus a space or area being protected.
• On IMO Fire Control Plans, symbols with the letter F usually relate to foam systems; some mark equipment (like monitors or inlets), others mark the boundary/space protected by foam.
• Compare how the plan shows a space protected by other agents (for example CO₂ or sprinkler coverage elsewhere on the sheet) and look for a similar style of “area/space” symbol but labeled for foam.
💭 Think About
• Which of the numbers 13, 16, 15, or 17 looks like it represents a zone or coverage area, rather than a single appliance such as a nozzle, hose, or monitor?
• Can you find on the sheet how a space protected by CO₂ or sprinkler is drawn, and then match that style to the foam-related symbols that use the letter F?
• Among the four options, which symbol would most logically be used to shade or mark an entire compartment on a plan, not just one point on the bulkhead or deck?
✅ Before You Answer
• Identify which choice shows a valve symbol (these do not represent a whole space).
• Identify which choices clearly show a monitor/nozzle or connection (these are pieces of equipment, not spaces).
• Confirm that the symbol you select could reasonably be drawn across or within a compartment outline on a plan to indicate “this entire space is foam-protected,” rather than placed at a single spot.
