Which regulation requires maintenance of operational safety for all maritime personnel?

The Maritime Labor Convention (MLC) is designed specifically to ensure that seafarers are treated fairly and have decent working and living conditions on board ships. One of its key provisions includes maintaining operational safety standards for all maritime personnel. This regulation aims to protect the rights of seafarers and promote their well-being at work, ensuring they have the necessary support, training, and safety measures in place to perform their duties safely.

The other options, while related to maritime operations and safety, focus on different areas. The International Maritime Organization (IMO) sets a global framework for maritime regulations but does not specifically focus on personnel welfare and safety. The Safety of Life at Sea (SOLAS) convention primarily covers ship safety standards and emergency procedures, while the International Ship and Port Facility Security (ISPS) Code focuses on security measures against acts of terrorism and does not specifically address operational safety for personnel. Therefore, B is the most relevant choice in relation to maintaining operational safety for maritime personnel.
