Question 1 of 27070

Each inert gas system gas main must have an automatic shut down valve at the outlet of the gas production plant. This valve must close automatically upon __________.

🔍 Key Concepts

• Inert gas system safety functions – what conditions could make it unsafe to keep sending gas to cargo tanks? • The role of the automatic shut down valve at the gas plant outlet – is it protecting against machinery failure, deck seal problems, or cargo equipment issues? • Think about which event would most directly affect the supply of inert gas from the plant itself.

💭 Think About

• Which of these options happens at the gas production plant versus out on deck or in cargo systems? • If this valve stays open during that event, could you lose control of gas quality or pressure going to the tanks? Which option best matches that risk? • Ask yourself: which failure would mean the system is no longer producing or moving inert gas safely, so the safest action is to shut the main outlet right away?

✅ Before You Answer

• Identify which choice is directly tied to the inert gas plant machinery (fans/blowers, generators) rather than cargo pumps or deck water levels. • Consider the main safety purpose: prevent unsafe gas (wrong pressure or composition) from entering cargo tanks when the plant can’t operate correctly. • Eliminate any option that is more about cargo handling equipment than about the inert gas production/supply equipment itself.
