Petroleum cargo tanks should not be topped off at deck level when loading on a cold day due to which of the following?
AI Explanation
The correct answer is B) a subsequent temperature rise will cause the cargo to overflow.
When loading petroleum cargo on a cold day, the cargo tanks should not be topped off at deck level. This is because as the cargo warms up, it will expand and can cause the cargo to overflow from the tank. The increase in temperature leads to an increase in the volume of the cargo, which will then exceed the available tank capacity if the tank was filled to the deck level during the cold conditions. The other answer choices do not accurately describe the reason for this practice.
