What color is the standard marking on a Nitrox tank wrap?

The standard marking on a Nitrox tank wrap is yellow with bold green letters. This color scheme is widely recognized in the diving community as it provides clear visibility and distinguishes Nitrox tanks from those containing regular air. The use of yellow is particularly effective in various lighting conditions underwater, ensuring that divers can easily identify tanks filled with enriched air mixtures that contain higher levels of oxygen.

This yellow background with green lettering is important for safety, as it helps prevent accidental use of tanks that contain other gas mixtures, which can lead to serious incidents if used incorrectly. It serves as a universal color code that reinforces the message of caution and awareness when handling gas mixtures. Thus, understanding and recognizing this color marking is crucial for divers, ensuring they manage their gas safely and appropriately during dives.
