Question 79Safety & Environmental - Assistant Engineer

The correct answer is C) Signal the shore control point to shutdown. This is the correct action because the top priority in this situation is to immediately stop the flow of oil from the tank vent. Signaling the shore control point to shut down the transfer operation will stop the flow of oil at the source, which is the most effective way to mitigate the spill. The other options, such as closing the vent valve or attempting to contain the spill, are secondary actions that should be taken after the flow has been stopped. The other answer choices are incorrect because they do not address the root cause of the issue. Closing the vent valve or setting up containment would not stop the flow of oil, and opening an adjacent tank could potentially worsen the situation by allowing more oil to spill.
