What are “stickers” used for in Nitrox diving?

Stickers in Nitrox diving are primarily used to label tanks according to their gas content. This serves a crucial safety function, as it helps divers easily identify the specific gas mixture contained within each tank, including the percentage of oxygen and nitrogen. Proper labeling is essential to prevent accidental mixing of gases, using the wrong tank at depth, or exceeding the maximum operating depth for a specific gas mixture. Accurate labeling ensures that divers can maintain safe dive practices, particularly when multiple gas mixtures may be used on the same dive.

In contrast, markings related to water clarity, buddy teams, or equipment checks do not specifically pertain to the identification of tank contents and are generally managed through other methods or systems in diving. Thus, the labeling of tanks with stickers serves as a direct and effective means of maintaining safety and awareness in Nitrox diving.
