🔍 Key Concepts

• Ventilation during shipboard fires – why and when you move smoke and hot gases out of a space • Difference between removing smoke/heat and supplying fresh air to a fire • How water drainage, crew comfort, and fire containment are normally handled on board

💭 Think About

• Look closely at the red arrows and gray smoke in Figure 2: what is being moved, and in which direction, when the doors and portholes are opened? • Ask yourself: does opening these openings add more oxygen to the fire, remove something from the compartment, or change how water behaves? • Which option matches standard fire‑fighting practice for improving visibility and access without deliberately feeding the fire?

✅ Before You Answer

• Identify what the red arrows and smoke clouds in Figure 2 represent (heat/smoke vs. water flow vs. air intake). • Decide whether opening portholes/doors is mainly about crew comfort or about fire behavior and safety. • Eliminate any choice that would obviously increase the fire’s intensity instead of helping control it.
