CGA C-9-2019 (R2024)
Standard Color Marking of Compressed Gas Containers for Medical Use
Although product labeling and CGA outlet connection identification are the primary and secondary means of identification, color is used as an additional aid for identifying the contents of compressed gas containers for medical use and for designating certain containers for use with specific medical gases. This standard shall apply to all sizes of containers used with gases for medical use as listed in the U.S. Federal Food Drug and Cosmetic Act. This standard also applies to these gases in Canada.
