You must provide documentation that you are a certified diver in order to fill a SCUBA cylinder. Additional certifications are required for Nitrox and Trimix fills.
Do I need a diving certification in order to get a sport diving gas fill?
Yes. To receive an Air fill, we require a SCUBA diving certification. To receive a fill with any Nitrox mixture of 40% or less Oxygen content, we require a Nitrox Diver certification.
What type of certification must I have to get a technical diving gas fill?
To receive a fill with any hyperoxic mixture greater than 40% Oxygen content (including pure Oxygen), we require a Technical Diver or equivalent certification. To receive a fill with Helium mixtures, a Trimix Diver or equivalent certification is required. We will observe any specific mixture restrictions that appear on your C-card. We interpret Normoxic Trimix to mean a Helium mixture with an Oxygen content between 18% and 24%.
What if someone else is getting fills on my behalf, and they don’t have the appropriate certification?Unless you have made prior arrangements, we will not allow anyone who lacks appropriate certification to receive a cylinder. In particular with breathing gases other than air, because divers should always analyze and label their own cylinder contents, those divers should be the ones picking up the cylinders.
