Type B packaging is designed to withstand what?

• A. Extreme accident conditions such as train or plane crashes without leaking
• B. Low-level leak
• C. No risk
• D. Not used for radiation

Answer: (A)

Type B packaging is built to survive the most severe transport accidents and still keep its contents contained. It must remain leak-tight and shield the material even when subjected to extreme scenarios like a train or aircraft crash, as well as other demanding accident conditions encountered during transport. This level of robustness is what distinguishes Type B from other packaging classes and is why the best choice is that it is designed to withstand extreme accident conditions without leaking.

It's not about preventing any leak in all situations, which would imply no risk at all, and Type B packaging is specifically intended for radioactive materials, so saying it's not used for radiation would be incorrect.
