🔍 Key Concepts

• Look for symbols on a fire control plan that represent fittings which CONTAIN or LIMIT a fire, rather than those that detect or extinguish it • Think about structural fire protection items like fire doors, dampers, or insulated bulkheads that slow the spread of flames and smoke • Differentiate firefighting equipment (extinguishers, hoses, valves, electrical cut‑outs) from items that form a barrier to fire

💭 Think About

• Among symbols 32, 33, 34, and 68, which one looks like a door, barrier, or damper rather than a movable piece of firefighting gear or an electrical fitting? • On an actual ship, which of these four items would physically stop fire or smoke from passing from one compartment to another? • Compare symbol 27 (arrows through a bulkhead) with the answer choices— which choice is most closely related to that idea of structural protection rather than active firefighting?

✅ Before You Answer

• Confirm which candidate symbol in the drawing is labelled on real fire control plans as a door, damper, or fire division rather than an extinguisher, valve, or switch • Double‑check that your chosen symbol would be part of the ship’s permanent structure or ventilation system, not a portable or electrical item • Verify in the legend that the symbol’s meaning is about containment/compartmentation, not about detection, alarm, or power control
