• C. Label and mark, classify material, select UN packaging, prepare inner packaging with cushioning, add absorbent, seal outer packaging, complete shipping papers, and load for transport.
• D. Classify material, select UN packaging, prepare inner packaging with cushioning, add absorbent, seal outer packaging, label and mark, complete shipping papers, and load for transport.

Answer: (D)

Classification must come first because it identifies the hazard class and packing group, which determine what packaging is allowed and what labeling and documentation are required. Once you know the hazard, you select UN packaging that meets the specified standards for that material. With the right packaging in place, you then prepare the inner packaging with cushioning to prevent movement and contain the material, and add absorbent to capture any potential leaks. The outer packaging is then sealed to create a secure, leak-tight container. Labeling and marking can only be accurate after the correct packaging and classification are known, since these communicate the hazard and regulatory details to handlers and inspectors. Next, you complete the shipping papers, ensuring all required information and emergency contacts are included. Finally, you load for transport, after verifying packaging integrity and proper documentation. This sequence ensures proper hazard identification, appropriate containment, and complete regulatory communication before movement.
