Which labels are required on a cryogenic shipper containing free-standing liquid nitrogen?

• A. All of the above
• B. Orientation label
• C. Green cryogenic handling label
• D. Class 2 Division 2 hazard label

Answer: (A)

Cryogenic shipments need clear labeling to communicate the hazards and how to handle them safely. For a shipper containing free-standing liquid nitrogen, you must use all three labels.

The Class 2 Division 2 hazard label identifies the contents as a non-flammable, non-toxic gas under cryogenic conditions, signaling the specific danger category to carriers and emergency responders. The orientation label tells handlers to keep the package upright, which helps ensure proper venting and integrity of the container during transport. The green cryogenic handling label warns that the contents are extremely cold and require special handling and PPE to prevent cold burns and damage from the low temperature.

Because each label serves a distinct safety purpose, all three are necessary, making “All of the above” the best answer.
