While underway with full LNG cargo tanks, an alarm indicates liquid in hold space #3. What should be the first action taken?
β’ LNG carrier safety procedures for cargo leaks β’ Difference between detecting/assessing a potential leak and taking corrective action β’ Dangers of sending personnel into a space that may contain flammable gas and low oxygen
β’ Before doing anything, what information do you need to confirm whether there is actually a dangerous leak or just an instrument indication? β’ Which actions could make a gas leak situation worse by adding ignition sources or exposing people to hazard? β’ In a suspected gas leak in an enclosed or semi-enclosed space, what are the usual priorities: measurement/monitoring, personnel safety, or immediate cargo transfer?
β’ Verify which option focuses on assessing conditions (pressure/temperature/atmosphere) before major actions are taken β’ Check which choices might endanger personnel or change the condition of the system without first confirming the situation β’ Eliminate any option that involves entering a potentially unsafe space before its atmosphere and structure are verified as safe
