A fire of escaping liquefied flammable gas is best extinguished by which action?

🔍 Key Concepts

• Fire tetrahedron – fuel, oxygen, heat, and chemical chain reaction • Behavior of liquefied flammable gas when its container or piping fails • Difference between controlling the fuel source vs. acting on oxygen, temperature, or chain reaction

💭 Think About

• Which part of the fire tetrahedron can you most realistically and safely control when a pressurized flammable gas is escaping? • What happens if you extinguish the visible flames but do NOT deal with the escaping gas itself near other ignition sources? • On gas fires, what is the usual first priority: act on the burning flame, or control the leak/fuel source?

✅ Before You Answer

• Verify which option directly addresses the source of fuel rather than just the visible flames • Consider which action, if done alone, might create a greater explosion hazard if the gas continues to escape unburned • Check standard guidance for gas-fed fires: what is the recommended primary control measure before other firefighting actions?
