What is the preferable way to extinguish a liquefied gas fire?

🔍 Key Concepts

• Class B (flammable gas) fires and how they are different from solid fuel fires • The importance of removing one side of the fire triangle (fuel, heat, oxygen) • Typical shipboard methods for controlling gas leaks vs. open flame

💭 Think About

• Ask yourself: with a liquefied gas fire, which action most directly deals with the fuel source rather than just the visible flames? • Which option would be safest in terms of avoiding spreading or dispersing the burning gas cloud? • Think about standard emergency procedures on tankers: what is usually the first priority when a flammable gas is burning?

✅ Before You Answer

• Verify which options mainly attack the flames (symptom) versus those that control the fuel supply (cause). • Consider whether using water fog or foam on a gas leak could risk spreading vapors instead of containing them. • Recall from fire-fighting training: what is the recommended initial action when you can safely control the source of a flammable gas release?
