I took a TDI Nitrox Gas Blending course today along with others at Sterling Silver Scuba. Our instructor was Danny Donnegan (Kemperite
) who was also certifying KevinD
as an instructor for the same course.
This course complemented well the Advanced Nitrox and Deco Procedures that I recently took since I’m now able to plan my mixes, optimize the blending to minimize cost for the fills (e.g., there are different ways to blend a given mix and I can figure out the best blend so that the overall fill is cheaper) and blend myself if I need to.
We learned about various aspect of pure oxygen safety, 02 clean equipment and maintenance, fill station configuration and maintenance, how to partial fill using pure oxygen and any nitrox top-off, optimizing using different prefilled banks, topping off non-empty tank, etc. It was pretty educational in terms of theory, lab and safety. The course required us to blend and fill a few cylinders. We calculated all mixes and blended them using pure oxygen. In the end, I ended up with my deco, travel and bottom mixes for next weekend deco training dives...
We’ll be at Dutch Springs next weekend (Aug 1-3). Stop by to say hello if you are around...
