Your vessel is securely moored to the berth preparing to discharge a cargo of LPG. Which of the following items would not comply with a "Safety Checklist" and should be corrected?

Correct Answer: Option A — the inert gas system deck water seal is drained and secured

Draining and securing an inert gas system deck water seal removes the vital non-return barrier protecting cargo tanks from backflow. Under 46 CFR and International Safety Guide for Oil Tankers and Terminals (ISGOTT) standards, this compromises tank isolation and fails safety pre-transfer checklists.
