I know you Republicans love to blame "da gubberment," but you need to take that to the "Pub," and share it with PF, it happens to be against the TOS in this thread.I see that part of that information (listed below) is regarding the changes allowing recreational Instructors to teach nitrox.
"On February 17, 2004 (see Federal Register notice 69 FR 7351), OSHA amended 29 CFR Part 1910, Subpart T - ("Commercial Diving Operations"), to allow recreational diving instructors and diving guides to comply with an alternative set of requirements instead of the decompression chamber requirements in the existing 29 CFR Part 1910, Subpart T standards. The final rule applies only when these employees engage in recreational diving instruction and diving-guide duties; use an open-circuit, a semi-closed-circuit, or a closed-circuit self-contained underwater-breathing apparatus supplied with a breathing gas that has a high percentage of oxygen mixed with nitrogen; dive to a maximum depth of 130 feet of sea water; and remain within the no-decompression limits specified for the partial pressure of nitrogen in the breathing-gas mixture. This final rule became effective on March 18, 2004."
This is burocracy at it's best. It's scary to think that the government in it's infinite wisdom will ever be out of debt again. The pencil necked geeks have got those guidelines laid out so that you have to be a commercial operation to be able to keep it going.
If the government ever takes over recreational diving, the whole sport will not survive.
All of this, just to blow a few bubbles?
Actually this is not bureaucracy at it's best, it's the short sightedness of the agencies. OSHA asked them back in the 1970s when the original recreational exemption was being prepared, how they should differentiate between commercial divers and recreational instructors. The agencies suggested that recreational instructors do, no-D, 130 foot limit, open circuit, air only diving. That's what they got as a definition. Decompression was out, deeper than 130 was out, CCR was out, Surface supplied was out, any media except air was out. So don't blame the government for this one, the agencies got exactly what they asked for, they just asked for the wrong thing. I guess you don't remember when DEMA was opposed to NITROX and when the Cayman Chamber claimed (at the behest of the operators) that they couldn't treat someone who was hurt while diving anything other than air?
We in the science community felt that those sorts of limitations were short-sighted and so we developed an exemption that was based on the purpose of the dives, the type of work being done, the qualities of the divers, the administrative structure and the right to refuse to dive without penalty. We were able to protect our ability to use any equipment and any technique to any depth as long as our administrative structure (Diving Control Board with a major or it's members being scientific divers) concurred.
