Question 77Safety & Environmental - 1st Asst/Chief

The correct answer is C) High temperature gas discharge from inert gas blowers. The inert gas system is designed to shut down automatically when the temperature of the gas discharge from the inert gas blowers exceeds a certain threshold, typically around 65°C (150°F). This is a safety measure to prevent damage to the system components and potential fires or explosions. The high temperature indicates a malfunction or failure in the system, and the automatic shutdown helps to mitigate the risk. The other options, while important parameters to monitor, do not typically result in an automatic shutdown of the inert gas system. A high temperature at the gas entering the scrubber or a low temperature of the water leaving the scrubber seal may trigger alarms or require operator intervention, but they do not automatically shut down the system. Similarly, a drop in oxygen content below 5% is a concern, but it does not necessarily trigger an automatic shutdown.
