| Re: Access to OC Oxygen from CCR?
This is a classic case of you needing to weigh up the pros and cons of each - as there are reasons for having it either way:
Pros:
Access to some O2 in bailout/DCS scenario, 3L @150bar at 6m @ 15SLM SAC = max 19mins at 6m - useful for sure, but based on some assumtions.
Cons:
Any sort of reg freeflow = loss of some O2. Could be mitigated by flowstop.
Any sort of hose failure, and you lose all your O2 - (no more likely than a failure of any other O2 hose you have, but more hoses = more risk)
I had one one, with a shut off, and a mouthpiece cover, never used it, decided that I would configure onboard(OB) = CCR only, so removed it. Also applied the same OB=CCR logic to dil too, and no longer have any OC option on my dil either. |
