How wide is the typical Nitrox tank wrap used to identify Nitrox cylinders?

The typical Nitrox tank wrap used to identify Nitrox cylinders is indeed designed to be between 10 to 13 cm wide. This size is practical because it is large enough to be clearly visible and easily recognizable by divers and dive operators, while not being overly large or cumbersome.

The purpose of the wrap is to provide a clear indication that the tank contains a gas mixture that is different from regular air, which usually consists of 21% oxygen and 79% nitrogen. As Nitrox mixtures can contain different levels of oxygen, typically 32% or 36%, the tank wraps serve as a safety reminder and help prevent accidental misuse or mislabeling.

Using an appropriate width for the wrap ensures that it can be seen from a distance, aiding in effective communication among divers and ensuring safety within the dive community. This is crucial in dive environments where multiple gas mixtures may be in use, helping divers quickly identify their tanks at a glance.
