🔍 Key Concepts

• Immediate safety precautions during LNG (liquefied natural gas) cargo operations • Behavior of LNG vapor (cold, heavier-than-air gas) and its fire/explosion risk • The purpose of emergency cargo shutdown vs. repair actions

💭 Think About

• Ask yourself: In an emergency leak situation, should you try to fix the hardware right away, or first control/stop the hazardous operation that is causing the leak? • Consider what happens to LNG and its vapors if you add water beneath a very cold leak—does this remove the hazard or potentially spread vapors? • Think about the correct order: secure the operation, control the hazard, then notify outside agencies. Which choice reflects that order?

✅ Before You Answer

• Identify which option immediately reduces the flow of LNG and therefore the size of the leak. • Check which options might increase risk (e.g., working near a live leak, creating more vapor, delaying shutdown). • Verify which action is normally required by ship/terminal emergency procedures as the first step when a leak is detected.
