🔍 Key Concepts

• Fully enclosed lifeboat design and purpose under SOLAS • How pressurized air systems protect occupants in fire/smoke/chemical situations • What systems on a lifeboat are usually mechanically driven vs. air driven

💭 Think About

• Think about which listed function is most critical to keeping people inside the lifeboat alive if the outside atmosphere is unsafe. • Consider which systems on a lifeboat are normally powered by the engine or pumps, and which actually depend on stored, pressurized air. • Ask yourself: does every enclosed lifeboat installation really need this function from the air bottles, or could it operate without it?

✅ Before You Answer

• Identify which options clearly relate to protecting occupants from a hazardous outside atmosphere. • Check which item describes something that is more likely provided by pumps/engine-driven systems instead of bottled air pressure. • Verify in current SOLAS and manufacturer diagrams what the air bottles are specifically piped to: engine intake, lifeboat interior, and/or spray system.
