Who should have the authority to approve hot work on a cargo ship carrying explosives?

The authority to approve hot work on a cargo ship carrying explosives lies with the Captain of the Port (COTP). This is because the COTP is responsible for ensuring the safety and security of the port area, particularly when dealing with dangerous cargo like explosives. The COTP has the expertise and jurisdiction necessary to evaluate the risks associated with conducting hot work in the vicinity of hazardous materials.

Hot work, which includes activities like welding or cutting, poses significant risks of fire or explosion, especially on vessels carrying explosive materials. Thus, having a central authority like the COTP helps ensure that all safety protocols and regulations are adhered to, minimizing the potential for accidents.

While the Dockmaster, Vessel Captain, and Chief Mate all have critical roles in vessel operations and safety, they do not possess the overarching authority that the COTP has in the context of port safety regulations regarding dangerous cargo. The COTP's role encompasses broader regulatory oversight, which is essential for decisions involving substantial risks such as hot work on ships carrying explosives.
