🔍 Key Concepts

• Compare airflow paths (white arrows) and smoke/exhaust paths (red arrows) between Figure 1 and Figure 2 • Think about which compartments are actually being ventilated in Figure 2 and which one still has trapped heat/smoke • Remember that you normally want to isolate unaffected spaces while ventilating the fire/smoke area

💭 Think About

• In Figure 2, trace the arrows: which compartments have a clear in‑and‑out path for air and smoke, and which compartment does not? • If the goal is to complete ventilation, which single change to doors/portholes would connect the unventilated space to the existing flow without opening up new, unaffected areas? • Would closing something in an already-ventilated path improve or reduce the flow of smoke out of the fire compartment?

✅ Before You Answer

• Identify which compartment contains the fire and check whether it has both an intake and an exhaust opening in Figure 2 • Verify which doors/portholes, if changed, would alter airflow through only the fire/smoke area and not disturb the isolation of compartment D • Confirm that the option you choose would create a continuous path: fresh air in → through the fire/smoke space → out the mechanical exhaust shown on the right
