The air regeneration canister on a survival...

🔍 Key Concepts

• Survival craft atmosphere control – why you need to treat the air inside an enclosed lifeboat or life raft • The difference between engine systems (starting, fuel, hydraulics) and life-support systems (air, water, food) • What happens to oxygen and carbon dioxide levels when many people are in a small, closed space

💭 Think About

• Ask yourself: which option deals with making the air inside a closed survival craft safe to breathe for an extended period? • Consider: which answers are clearly related to engines or hydraulics, and which one is related to the people’s ability to keep breathing safely? • Think about what “air regeneration” means in plain language—what is being regenerated, and why would that matter in an enclosed boat?

✅ Before You Answer

• Identify which choice directly concerns the composition of the air (O₂/CO₂) inside the craft, not the machinery. • Eliminate any options that only refer to starting the engine or pressurizing systems, since those are not about breathing air. • Remember that in enclosed survival craft, you must manage carbon dioxide buildup and oxygen supply to keep occupants alive.
