🔍 Key Concepts

• engine starting procedures for survival craft, especially in cold conditions • normal uses of ether (starting fluid) in combustion engines • typical systems found on a survival craft: engine, air supply, sprinkler/fog systems, and medical oxygen

💭 Think About

• On a survival craft, which piece of equipment actually uses a combustible starting fluid like ether? • Which of the listed systems would reasonably be mechanical and hard to start when temperatures are very low? • For each option, ask yourself: is ether something you would safely put into a breathing or sprinkler system, or is it something used somewhere else on the craft?

✅ Before You Answer

• Eliminate any option that would involve people inhaling ether as if it were oxygen or medical aid. • Think about what problem cold weather causes on a survival craft and which system is hardest to get going when it’s very cold. • Recall where starting fluid (ether) is commonly sprayed or injected on machinery. Match that common use to the most similar choice.
