Question 104Safety & Environmental - Assistant Engineer

The correct answer is B) secure the salt water supply to the scrubber. When securing an inert gas system, the final step should be to secure the salt water supply to the scrubber. This is because the scrubber is responsible for removing any particles or contaminants from the inert gas before it is distributed throughout the system. Securing the salt water supply to the scrubber ensures that the system is properly shut down and prevents any potential leaks or issues with the inert gas distribution. The other options, A) securing the inert gas blower, C) closing the deck isolating valve, and D) closing the flue gas isolating valve, are all important steps in the shutdown process, but they do not represent the final step as securing the salt water supply to the scrubber does.
