Which international treaty deals with the safe transport of dangerous goods?

The International Maritime Dangerous Goods (IMDG) Code is the correct answer because it specifically addresses the safe transport of dangerous goods by sea. This code provides a comprehensive set of guidelines designed to ensure that hazardous materials are packaged, labeled, stored, and handled in a manner that minimizes risks to safety, health, and the environment during maritime transport. It is critical for shipping companies and port authorities to follow these regulations to prevent accidents that could arise from the improper handling of dangerous goods.

In contrast, other options such as Safety of Life at Sea (SOLAS) focus more broadly on maritime safety and do not specifically cover the regulations for dangerous goods. The Convention on the International Regulations for Preventing Collisions at Sea addresses navigational rules to prevent collisions between vessels, which is unrelated to the specifics of dangerous goods transport. The Maritime Labor Convention (MLC) is concerned with seafarers' rights and working conditions, rather than the safe transport of hazardous materials. Each of these treaties serves important functions in maritime law, but the IMDG Code is unique in its focus on dangerous goods and their safe transport.
