What should divers do before diving with Nitrox regarding their tanks?

Before diving with Nitrox, it is essential for divers to analyze and label every cylinder they intend to use. This practice is crucial because Nitrox is a term used to describe a mixture of nitrogen and oxygen that contains a higher percentage of oxygen than regular air. The different oxygen levels significantly alter the way a diver should plan their dive, especially concerning depth limits and no-decompression limits.

By analyzing the gas mix in each tank, divers can ensure that they are aware of the exact composition, which helps prevent potential risks associated with oxygen toxicity at greater depths. Labeling each cylinder with its specific oxygen percentage also serves as a vital safety measure. It raises awareness among all divers using the tanks and assists in planning dives accurately, ensuring proper gas management and adherence to safe diving practices. Not recognizing the importance of this process could lead to serious accidents, making analysis and labeling an indispensable part of diving with Nitrox.
