The packaging for this must be able to maintain the normal rigors of air transport and extremely low temperatures, the net weight of dry ice must be marked outside of the package. Which option describes these requirements?

• A. It must be airtight and waterproof, with net weight marked outside
• B. It must withstand the normal rigors of air transport and extremely low temperatures, and the net weight must be marked outside the package
• C. It must be biodegradable and compostable
• D. It must be heat-sealed and vented

Answer: (B)

Packaging for dry ice shipments must be able to withstand the normal rigors of air transport and the extremely low temperatures involved, and it must have the net weight of the dry ice marked on the outside of the package. This reflects two essential aspects: first, the package needs to survive handling, vibration, pressure changes, and the cold wherever air travel takes it, while also accommodating the sublimation of dry ice without creating unsafe pressure inside the package; second, clearly marking the outside with the net weight helps handlers and regulators assess venting needs, contact points for safety, and proper handling. The other options don’t meet both requirements: being airtight and waterproof isn’t appropriate because dry ice sublimation requires venting; focusing on biodegradability isn’t related to transport conditions; and while venting is useful, claiming the package must be heat-sealed doesn’t align with standard dry ice packaging practices and it still wouldn’t explicitly require the outside marking of net weight.
