What color is commonly used to identify oxygen cylinders?

Oxygen cylinders are commonly identified by the color green. This standardization helps ensure that individuals can easily recognize the type of gas contained within the cylinder, which is crucial for safety in environments such as medical facilities, laboratories, and various industries. The consistent use of green for oxygen facilitates quick identification and minimizes the risk of accidental mix-ups with other gases that may have different color codes. Having a universal color code for gases like oxygen is vital to maintaining a safe working environment and ensuring that emergency procedures can be followed without confusion.
