What is the purpose of segregation in the same shipment?

• A. Prevents dangerous interactions between incompatible goods (e.g., acids with bases, oxidizers with fuels).
• B. Increases the weight of the shipment.
• C. Expedites customs clearance.
• D. Reduces labeling requirements.

Answer: (A)

Segregation in a single shipment is about keeping incompatible dangerous goods apart to prevent hazardous interactions during handling and transport. When certain substances meet, they can react violently, release heat, form toxic gases, or ignite. By maintaining separation—whether through physical distance, barriers, or separate inner packaging—regulations reduce the risk of those dangerous reactions between substances like acids and bases or oxidizers and fuels. This separation is the central safety principle of packing goods together without danger. It doesn't aim to change the shipment's weight, nor does it serve to speed up customs clearance. And labeling requirements are not inherently reduced by segregation; the labeling is driven by the classification of each item, and safety communications must be maintained or even enhanced as needed.
