Question 804 Deck General

The correct answer is C) an officer assigned to the vessel. The handling and stowage of packaged hazardous materials on board a domestic vessel engaged in foreign trade must be done under the supervision of an officer assigned to the vessel. This requirement is specified in the Code of Federal Regulations (CFR), Title 46, Section 146.02-1, which states that the "master or person in charge of the vessel" is responsible for ensuring the proper handling and stowage of hazardous materials. The other options are incorrect because the National Cargo Bureau (A) is an independent organization that provides inspection services, but is not responsible for the direct supervision of hazardous materials handling on board the vessel. The U.S. Coast Guard Marine Inspector (B) and the American Bureau of Shipping (D) are also not responsible for the direct supervision of the hazardous materials handling, which is the responsibility of the officer assigned to the vessel.
