| Re: Is Rebreather diving inherently more dangerous than OC?
yes their is a minimum danger from rebreathers that isnt there on OC, if you forget to turn the unit on hypoxia will lead to death.
However moving away from the 'how easy to kill yourself' debate a paticular situation could be safer on either.
OC has less complexity, less things to go wrong, easier redudancy and no relaince on electronics / user operation.
CC gives the advantage of extra duration safety margin, safer deco (considering same profile OC).
This means that where the kit / setup / dive is complex a rebreather is often safer as the added complexity of the rebreather is ofset by its advantages over OC for this dive. Hence a good reason for CC on techincal dives
Where the dive is simple / shallow / no deco / infrequent OC is safer as the safer profiles arent significant compared to the complexities. |
