🔍 Key Concepts

• Totally enclosed survival craft design and purpose • Common maintenance needs after long exposure to seawater and weather • Systems on survival craft that can be damaged or clogged by salt and marine growth

💭 Think About

• Think about which system on a totally enclosed survival craft is most likely to deteriorate or become inoperative after being exposed to seawater for a long time. • Ask yourself which option relates to preserving an emergency safety system, rather than just comfort for the occupants. • Consider which choice addresses something that, if not maintained, could fail when you need it most during an actual emergency.

✅ Before You Answer

• Identify which answer choice deals with a critical life‑saving function, not comfort or minor convenience. • Consider how saltwater and spray affect small nozzles, pipes, and mechanical systems over time. • Verify in your survival craft training materials which systems require fresh water flushing to keep them operational after long periods afloat.
