What is the purpose of the segregation table in IATA DGR?

• A. It shows the order of loading.
• B. It provides guidance on how different hazard classes should be separated in the same shipment.
• C. It lists permitted packaging types.
• D. It determines shipping routes.

Answer: (B)

The purpose of the segregation table is to keep incompatible dangerous goods apart within the same shipment. It provides guidance on how different hazard classes should be separated from one another in the same package or transport unit, specifying when items must be stored away from each other or separated by partitions and physical spacing. This helps determine whether two items can ride in the same shipment and what level of separation is required to prevent unwanted interactions, such as reactions, fires, or gas release. For example, oxidizers are kept away from flammable liquids, and certain class combinations require clear separation to maintain safe transport. The options describing loading order, permitted packaging types, or routing do not describe this separation guidance.
