🔍 Key Concepts

• Review the IMO fire control plan symbols used on shipboard safety plans. • Distinguish between the symbol for the main fire control plan and the symbol for a duplicate/spare plan kept in a weathertight enclosure. • Look closely at how colors or diagonal divisions are used to show that something is "inside" vs "outside/duplicate."

💭 Think About

• Identify which numbered symbol clearly represents the primary fire control plan itself, then look for a related symbol that might indicate an additional or spare set. • Compare the symbols around numbers 1, 30, 37, and 69 and ask: which one specifically suggests a container or special marking for a stored copy, rather than a general fire‑fighting device or area? • Think about SOLAS requirements: where is the spare set of fire control plans normally kept, and how might that be shown graphically (e.g., special background, divided color, or border)?

✅ Before You Answer

• Confirm which number corresponds to the symbol that literally says FIRE PLAN and recognize that as the main plan, not necessarily the spare set. • Eliminate any option that is clearly a symbol for a fire extinguisher, fire equipment room, or other fire‑fighting appliance rather than documentation storage. • Focus on the option whose symbol looks like a sign/marker indicating a special enclosure for documents, especially one with a distinctive diagonal color split often used for duplicate external plans.
