Why is it important that the PSN corresponds to the UN number and class?

• A. To ensure accurate identification of the material and proper compliance with packaging, labeling, and documentation requirements.
• B. To improve marketing.
• C. To reduce shipping time.
• D. To decrease insurance.

Answer: (A)

The main idea here is that the PSN (Proper Shipping Name) must line up with the UN number and hazard class so everyone can identify the material correctly and apply the right handling rules. The UN number identifies the exact substance, and the class shows the hazard category, which together tell you exactly which packaging instructions, labeling, and documentation are required. When the PSN matches the UN number and class, shipping papers, labels, and packaging reflect the true nature of the dangerous goods, guiding safe handling, appropriate containment, and proper emergency response. This alignment prevents mislabeling or using wrong packaging and ensures compliance with regulations. The other options aren’t about regulatory identification or safety requirements, so they aren’t the goal of matching the PSN to the UN number and class.
