aphelion:
I'm not an OSHA guy, but it looks like the above link is for Commercial Diving Operations, and it's just a proposal from 2003, not a real rule.
I found part of the approved standard called "Alternative Conditions Under 1910.401(a)(3) for Recreational Diving Instructors and Diving Guides (Mandatory) - 1910 Subpart T App C" that seems to modify the commercial code for the folks we're talking about:
OSHA Part 1910 Stuff
It says "Paragraph (a)(3) of § 1910.401 specifies that an employer of recreational diving instructors and diving guides (hereafter, "divers" or "employees") who complies with all of the conditions of this appendix need not provide a decompression chamber for these divers as required under §§ 1910.423(b)(2) or (c)(3) or 1910.426(b)(1)."
There's a section 6 down near the bottom which shows the requirements for "Mixing and Analyzing the Breathing Gas"
I haven't looked at this in depth, with all the subparts and mumbo jumbo. Maybe it applies...
