Question 1577 Deck General

70% to pass

In special cases, the Commandant of the Coast Guard may permit cargo piping to pass through machinery spaces. This is permitted provided that the only cargo carried through such piping is(are) which of the following?

A LFG
B grades D or E
C grade E
D grades A or B
AI Explanation

The correct answer is C) grade E. The Coast Guard regulations permit cargo piping to pass through machinery spaces only if the cargo being transported is grade E. Grade E cargo refers to the least hazardous category of liquid cargoes, which includes things like certain lubricating oils and some slightly flammable chemicals. This exception is allowed to provide more flexibility in the design and layout of the cargo piping system, provided the risk of the cargo being transported is low. The other options are incorrect because LFG (liquefied flammable gas) and grades A or B cargoes are more hazardous and would not be permitted to pass through machinery spaces, while grade D cargoes are not the lowest hazard category.
