How are dangerous goods identified in international regulations?

Dangerous goods are identified in international regulations primarily by their proper shipping name and associated classifications. This system is crucial because it provides a standardized way to categorize various substances based on their chemical and physical properties, which can include flammability, toxicity, explosiveness, and environmental hazards. Each hazardous material is assigned a specific shipping name that reflects its nature and associated risks, allowing for consistent communication across borders and modes of transport.

Classifications further detail the specific hazards associated with each substance, ensuring that those handling, transporting, or storing these goods recognize the necessary precautions and emergency measures. This system is vital for maintaining safety standards in the transportation of dangerous goods globally, given the diverse range of materials that can be characterized as hazardous.

Other options, while related to the transport process, do not accurately encapsulate the method used to identify dangerous goods. Weight and dimension may be considerations for transport logistics but do not define the hazard level. The location of the shipment and the shipper's registration number are not relevant identifiers for the classification of dangerous goods themselves.
