Using medical O2 for aviation...

I thought we settled this twenty years ago.

Medical, welding, and aviator's breathing oxygen are all produced using the same processes and equipment. Not just similar. They're all the exact same stuff from the same tap.

The only differences are what they're dispensed into and how they're used. The requirements for purity and cleanliness in all compressed oxygen applications are such that the baseline specifications for all are the same.

I mis-spoke, I meant to say jury rigging med O2 equipment for a purpose not intended, could be hazardous to one's health. Kind of thought that was implied, forgot an engineer or two populates these pages. I have had hypoxia before during a contest out of INYK. I later realized I had mixed equipment from Aerox and MH. Aerox oxyisaver cannula cannot be used with MH equipment. I would strongly encourage anyone to use the equipment from the manufacturer, read the instructions and not attempt to jury rig a mix of med O2 and aviation O2 equipment.

What/where is INYK? Sorry, can't find it.
