Generated guidance. Confirm the source and its applicability before you act. How we check sources.
Based on 49 CFR 172.405, here is what is required and allowed regarding label modifications for your motor-carrier operations:
* Classes 1, 2, 3, 4, 5, 6, and 8: Text that indicates a hazard (such as "FLAMMABLE LIQUID") is not required on either primary or subsidiary labels.
* Compressed or Refrigerated Liquid Oxygen: If you are shipping oxygen packages, you may use a modified OXIDIZER label instead of separate NON-FLAMMABLE GAS and OXIDIZER labels. This modified label must display the word “OXYGEN” (which is strictly required, overriding the general exemption in paragraph (a)) instead of “OXIDIZER”, and it must show the class number “2” instead of “5.1”.
* Division 6.1, Packing Group III Materials: For packages containing these materials, you can modify the standard POISON label so that the text “PG III” appears below the mid-line of the label instead of “POISON” or “TOXIC”.
