What does the large green and yellow Nitrox decal mean?
Per PSI standards, presence of a color-coded 6-inch-wide green and yellow NITROX band decal indicates only that the cylinder contents are Nitrox. The large NITROX band does not indicate the cleanliness of the cylinder, its suitability for partial pressure blending, or what method was used to fill the cylinder. It is only the evidence of inspection sticker that indicates if a cylinder and valve are Nitrox Ready.
