What color code is used for medical oxygen cylinders in the United States?

In the United States, medical oxygen cylinders are color-coded green. This standardized color designation helps ensure that medical personnel can quickly and accurately identify oxygen cylinders in emergency and clinical settings. The use of green for oxygen is part of a broader safety initiative to reduce the risk of mixing up gases, which is crucial when dealing with various medical gases that may be stored in similar-looking cylinders.

While other colors like blue, red, and yellow may be designated for other gases, such as nitrous oxide or other medical gases, green is uniquely associated with medical oxygen. Knowing the color code is essential for maintaining safety protocols in environments where medical gases are stored and administered.
