Question 2 TK01 - Tank Vessel Assistant - Dangerous Liquids

The Correct Answer is D **Why option D ("refer to the vessel's Certificate of Inspection") is correct:** The vessel's Certificate of Inspection (COI) is the official regulatory document issued by the U.S. Coast Guard (or equivalent authority for foreign flag vessels) that explicitly defines the operating parameters, structural limitations, manning requirements, and—most critically—the specific grades and types of dangerous cargoes (hazardous materials) the vessel is authorized to transport. This document ensures the vessel meets all safety and environmental regulations for carrying those materials. **Why the other options are incorrect:** * **A) examine the cargo tanks and fittings:** While the condition of tanks and fittings is critical for safe carriage, simply examining them does not determine the *legal* authorization or classification of the vessel for carrying specific cargo grades (such as Grade A, B, C, D, E for flammable/combustible liquids). That legal classification is only found in the COI. * **B) ask the terminal supervisor or his representative:** The terminal supervisor's primary role is managing the loading/unloading operation at the facility. While they must confirm the vessel is suitable, they rely on the vessel's official documents (like the COI) provided by the ship's crew. They do not possess the authority or documentation to define the vessel's permitted cargo grades. * **C) check the loading order:** The loading order (or cargo manifest/plan) details the cargo *to be loaded* for a specific voyage, but it does not serve as the regulatory document dictating the maximum allowable grades the vessel is permitted to carry in general. The contents of the loading order must conform to the limitations set forth in the COI, not define them.
