Question 1064 Deck General

The correct answer is B) 5%. According to the regulations for crude oil washing with an inert gas system, the inert gas system must produce and deliver inert gas with an oxygen content of 5% or less by volume. This ensures that the atmosphere in the cargo tanks remains inert and safe for crude oil washing operations. The other options are incorrect because 0% oxygen content is too low and would not allow for proper combustion during the crude oil washing process, while 8% and 11% oxygen content would be too high and potentially create an explosive atmosphere in the cargo tanks.
