Biomedical waste must follow which packing instruction?

• A. Packing Instruction 650
• B. Packing Instruction 620
• C. Packing Instruction 621
• D. Packing Instruction 630

Answer: (C)

Transporting biomedical waste by air is governed by a packing instruction that is specifically designated for biomedical waste. This instruction outlines exactly how the waste must be packaged to prevent leakage, contamination, and exposure during handling, transit, and unloading. It requires a layered packaging approach: an inner leakproof container, placed in absorbent material, inside a secondary container, all within a rigid outer packaging that meets strength standards. The outer packaging must be properly labeled and accompanied by any necessary documentation to show it is biomedical waste.

This instruction is the one that matches biomedical waste and its handling needs. The other packing instructions cover different categories of biological materials or infectious substances (for example, samples that are not treated as waste, or substances that pose different risk levels). So the dedicated biomedical waste packing instruction is the correct and best fit because it directly addresses the containment, labeling, and safety requirements for waste materials from healthcare or research settings.
