Who designates, in writing, the ship's hazmat coordinator?

The ship's hazmat coordinator is designated in writing by the Commanding Officer. This individual is responsible for overseeing hazardous materials management, ensuring compliance with safety regulations, and providing training to the crew on proper handling and disposal procedures for hazardous materials. The Commanding Officer, who holds the highest authority aboard, has the ultimate responsibility for the safety and operational integrity of the vessel, including the management of hazardous materials. This designation is crucial, as it establishes a clear line of accountability and authority for hazmat matters, which is essential for maintaining safety standards on board.

The other roles listed, while important, do not typically encompass the full authority required to designate such a position. The Chief Engineer might handle machinery and engine-room operations, the Safety Officer focuses on overall safety protocols, and the First Officer assists with navigation and daily operations but lacks the overarching authority to formally designate the hazmat coordinator.
