Recreationall TRIMIX

[WIdiver_Paul]

"Acceptable Risk" is a paradigm that changes with time and awareness, as people begin to realise the dangers associated with things they may not be aware of. When I was young, my grandpa's buick had no seatbelts. It also had no crumple zones built into the frame and engine compartment. It had no airbags. It had no antilock brake system to stop accidents from happening in the first place. It had no side-impact zones. Auto makers had to find ways to make autos safer, regardless if the user was aware of the dangers, and they had to find ways to make them easy to use, to make driving safer for everyone. They had to make auto safety easy for everyone to get used to. This is the same idea behind recreational triox, to make safe semi-deep recreational dives as safe as possible, and accessible to those who are interested in becoming safer divers at that depth.


Anyone taking recreational trimix needs to have a nitrox certification, which means they already know what PO2 they are diving at and their O2 exposure. The oxygen is not the issue.


Here again this statement reinforces the validity of what you are arguing against:
Recreational triox was conceived to make diving safer with added helium at recreational depths without the half dozen classes, months of instruction and thousands of dollars of money wasted on instruction to get a student to a level possibly beyond the level at which they may dive. If they made having a commercial driver's license a prerequisite for driving a car, we'd all be riding our bicycles to work! You don't need a degree in medicine to put on a band-aid. Diving is founded on the principle that people assume personal risk to dive. Not everyone wants or needs to have a full cave card and training at 300' to dive 130' on helium.
