What color is a nitrogen tank typically marked in the USA?

In the USA, nitrogen gas tanks are typically identified by a black color. This standardization helps healthcare professionals, technicians, and emergency personnel quickly recognize the type of gas contained within the cylinder, which is crucial for ensuring safety and proper usage in various medical and industrial applications.

Color coding is an essential aspect of gas tank safety; different gases are assigned specific colors to prevent confusion and potential hazards that could arise from using the wrong gas or mixing gases inadvertently. While green is often associated with oxygen, blue with nitrous oxide, and red with fire-related gases, black is recognized as the standard for nitrogen. This clear differentiation aids in efficient and safe management of medical gases.
