Question 809 Deck General

The correct answer is D) grade E. According to the U.S. Coast Guard regulations, in special cases, the Commandant of the Coast Guard may permit cargo piping to pass through machinery spaces, but this is only allowed for cargo of grade E. Grade E cargoes are the least hazardous and have the lowest fire risk, making them the only type of cargo permitted to be carried through machinery spaces in such special cases. The other answer choices are incorrect because: A) Grades D or E are not permitted, only grade E is allowed. B) LFG (liquefied flammable gas) is a highly hazardous cargo that would not be permitted to pass through machinery spaces. C) Grades A or B are more hazardous cargoes that are not allowed to be carried through machinery spaces.
