Question 1204 Deck General

The correct answer is A) The certificated tankerman on duty. The reasoning for this is that the certificated tankerman is responsible for the safe handling of the cargo during loading operations. They have the authority to determine where smoking is permitted, as smoking is a potential ignition source that could be hazardous around flammable or explosive cargo. The vessel owner, OCMI, or a general prohibition on smoking during loading would not have the same level of direct responsibility and oversight over the specific loading operation as the certificated tankerman.
