Q

Generally, what is used to inflate liferafts?

🔍 Key Concepts

• Liferaft inflation systems on SOLAS-compliant vessels • Properties of safe gases for breathing and fire risk • Which common gases are toxic, flammable, or support combustion

💭 Think About

• Which of these gases would be safe to release in large quantities near survivors and possibly open flames? • Think about which gases are toxic, which are highly flammable, and which might make fires worse. • Liferafts may be boarded quickly after inflation—what gas would be safest for people to inhale accidentally?

✅ Before You Answer

• Eliminate any gas that is toxic to humans even in relatively low concentrations. • Eliminate any gas that is flammable or explosive in air. • Ask yourself which option best matches the idea of a chemically stable, non-reactive, non-toxic gas.
