What is the Dangerous Goods List (DGL) used for?

• A. It provides the approved proper shipping names, UN numbers, hazard classes, and packing groups for dangerous goods
• B. It lists only the packaging types allowed
• C. It contains emergency contact numbers only
• D. It is used to determine shipping rates

Answer: (A)

Understanding how dangerous goods are identified and documented for transport hinges on having a standard reference that lists the exact details needed to classify and handle each item. The Dangerous Goods List provides the approved proper shipping names, UN numbers, hazard classes, and packing groups for dangerous goods, which are the essential pieces of information used on shipping papers, labels, and packaging to ensure correct identification, appropriate packaging, and proper handling throughout the supply chain. This standardized data helps shippers, carriers, and authorities determine the correct precautions and regulatory requirements for each substance. It isn’t limited to packaging types, emergency contact numbers, or shipping rates—those aspects are covered by other resources, while the DGL focuses on the precise classification and documentation details that enable safe, compliant transport.
