Question 1257 Deck General

The correct answer is B) insulating flange or single length of non-conducting hose. When hooking up a cargo hose to your vessel manifold, you should use an insulating flange or a single length of non-conducting hose. This is to prevent the potential for stray electrical currents or static electricity buildup, which could lead to a fire or explosion hazard. Regulations require the use of this insulating equipment to ensure safe cargo transfer operations. The other options are incorrect. A) self-contained breathing apparatus is used for personnel safety in hazardous atmospheres, not for cargo hose connections. C) international shore connection is a specific fitting used for shore-to-ship connections, not for cargo hose hookups. D) oxygen analyzer is used to monitor oxygen levels, not for the cargo hose connection itself.
