Which label is required on all packages containing cryogenic liquids, in addition to the Non-flammable gas (Division 2.2) hazard label?

• A. Non-flammable gas (Division 2.2) hazard label
• B. Cryogenic Liquids
• C. Radioactive Material, Excepted Package
• D. Keep Away From Heat

Answer: (B)

Labeling for cryogenic liquids requires conveying both the gaseous hazard and the extreme cold. Packages containing cryogenic liquids must show the Cryogenic Liquids label in addition to the Non-flammable gas (Division 2.2) hazard label. The 2.2 label warns handlers that the contents are a non-flammable gas, but it doesn’t communicate the additional risk from extremely low temperatures that can cause severe cold burns, embrittlement, or rapid condensation of surrounding materials. The Cryogenic Liquids label specifically flags this temperature hazard and prompts appropriate PPE, handling, and storage precautions. The other options don’t fit because the radioactive material label is for radioactive shipments, and Keep Away From Heat is a handling instruction, not a required hazard label.
