Q

Generally, what is used to inflate liferafts?

🔍 Key Concepts

• Types of gases that support or do not support combustion • Requirements for safe storage of inflation cylinders inside a liferaft container • Why certain gases are chosen for inertness (non-reactivity) and availability

💭 Think About

• Think about which gas would be safest inside an enclosed raft where people may be breathing close to the inflation valves and hoses. • Consider which of these gases are commonly used in fire extinguishers and fixed-flooding systems because they don’t support burning. • Ask yourself which gases on the list are dangerous because they either feed fire or are highly flammable.

✅ Before You Answer

• Eliminate any gas that supports combustion strongly (makes fires burn more). • Eliminate any gas that is itself highly flammable or explosive. • Focus on gases that are inert, non‑toxic in typical quantities, and easy to store under high pressure.
