Which color code represents air in medical gas cylinders?

In medical gas cylinders, the color code representing air is commonly identified as black. However, in the context of medical gases, air is typically stored in a cylinder marked with a green color code in many regions, particularly in the United States. The use of color codes is essential for ensuring the safe handling and administration of gases in medical environments. Each color corresponds to a specific type of gas to minimize the risk of errors and ensure the correct gas is delivered to patients.

The color coding is standardized to enhance safety, communication, and training. For instance, oxygen is usually designated as green, nitrous oxide is blue, and other gases are marked with different colors as well. Therefore, one must have a clear understanding of these color codes to work effectively in respiratory care and ensure optimal patient safety.
