🔍 Key Concepts

• SOLAS requirements for totally enclosed lifeboats in case of fire on the water’s surface • How air supply and engine intake are arranged when the lifeboat is surrounded by flames and heavy smoke • Design features like water spray systems and automatic closures/ventilators on modern enclosed lifeboats

💭 Think About

• Ask yourself: When the boat is completely surrounded by fire and smoke, where should the breathing air and engine air logically come from to keep everyone safe? • Think about which systems must be automatic (require no crew action during panic) versus which could reasonably be manual and still be safe and effective. • Consider the main purpose of a totally enclosed lifeboat: to protect occupants from heat, flame, and smoke. Which options clearly support that purpose, and which might actually increase danger?

✅ Before You Answer

• Check which choice clearly indicates that air is available inside the boat for both survivors and the engine during a brief passage through flames. • Verify whether a lifeboat designed for fire conditions would ever depend on outside air while passing through burning oil or heavy smoke. • Look at each statement and ask whether it sounds like a SOLAS-type standardized feature of totally enclosed lifeboats, rather than something that would be unreliable or unsafe in an actual fire situation.
