Question 774 Deck General

The correct answer is A) The senior deck officer on duty or certified tankerman. During a loading operation on a barge carrying grade A cargo, the senior deck officer on duty or certified tankerman has the authority to determine where smoking may be permitted. This is in accordance with regulations that require the person in charge of the loading operation to establish and enforce safety procedures, which includes designating any safe smoking areas. The other options are incorrect because the OCMI (Officer in Charge of Marine Inspection) does not make this determination, smoking is generally prohibited during loading operations, and the vessel owner does not have direct control over the loading procedures.
