Question 1125 Deck General

The correct answer is D) 8%. The reason for this is that according to the regulations set by the U.S. Coast Guard, the maximum percent of oxygen, by volume, allowed to be maintained in the cargo tanks prior to the commencement of crude oil tank washing is 8%. This limit is in place to ensure the safe conduct of tank washing operations and to minimize the risk of fire or explosion. The other options are incorrect because 5% (A) is too low, 12% (B) is too high, and 10% (C) does not meet the regulatory requirement of 8% maximum oxygen content.
