Question 1062 Deck General

The correct answer is D) grade E. According to Coast Guard regulations, the Commandant may permit cargo piping to pass through machinery spaces, but the only cargo that can be carried through such piping is grade E. Grade E cargo, which includes lubricating oils, fuel oils, and other flammable liquids with high flash points, is the only type of cargo allowed to be routed through machinery spaces in special cases. The other answer choices, such as grades A or B (low flash point flammable liquids) or LPG (liquefied petroleum gas), are not permitted to be routed through machinery spaces due to the increased fire risk.
