🔍 Key Concepts

• SOLAS requirements for survival craft engines and their fuel • Fire and explosion risk of different fuel types on small enclosed craft • Storage stability and safety of fuels in emergency equipment

💭 Think About

• Which of these fuels would be safest to store for long periods inside or on an enclosed lifeboat or rescue boat? • Which fuel type presents the least risk of vapors igniting or exploding in a confined space? • Think about what commercial ships commonly use for their main and auxiliary engines—does that influence what is chosen for survival craft?

✅ Before You Answer

• Compare volatility and vapor explosion risk of each fuel type • Consider long‑term storage and stability in emergency equipment that may not be used for months or years • Ask which fuel is most commonly used in marine engines for reliability and safety
