Nevertheless, I think that, if the agencies are going to issue solo cards, they should probably separate out rec solo from tech solo.
May I inquire as to why you think there should be two different solo certs?

It's not a theory. The c-card tells us the person can dive without supervision. That is its only purpose.
1910.401(a)(2)
“This standard applies to diving and related support operations conducted in connection with all types of work and employments..”
OSHA does not use the term commercial or sport, nor does it use the term "technical>" It does have definitions for recreational and scientific because of the exemptions it provides in those settings.
The instructor at the LDS is employed in a commercial dive operation that is subject to OSHA rules regarding dive operations conducted in connection with all types of work and employment, unless the operation meets the OSHA exemptions. Having to meeting the terms of the exemption is a form of regulation.
OSHA:• Part Number: 1910
• Part Title: Occupational Safety and Health Standards
• Subpart: T
• Subpart Title: Commercial Diving Operations
• Standard Number: 1910.401
• Title: Scope and application.
The earliest date on the OSHA regs regarding diving is July 22, 1977. Whether the 130 foot limit that is found in the regs exempting recreational instruction from other provisions of the regs was in the 1977 version or a subsequent amendment isn’t clear.

Surely one tech solo card is not enough ?
You would need:
Advanced Nitrox solo
Trimix solo
Advanced Trimix solo
Intro and Full cave solo
Rebreather solo
Night trimix sidemount cave drysuit solo etc etc etc.
IMHO divers at that level can figure it out for themselves.

Ian, by your reasoning, we would need a cert card to dive naked.
