I have no problem with beers during this process.
Then you have to wake up earlier because you have to rebuild your unit before breakfast with the others :wink:
 
There aren’t many alarms that will pull you out of all situations. I recall vibrating mouthpieces, blinking lights in your face, haptic devices on computers. Same same, not different. In the right circumstances, people can (and do) ignore all those things.
If you are already dealing with a major situation auditory exclusion etc may well be a part of that. But if you can ignore those the odds of you noticing anything less intrusive is pretty much nil.
 
Food for thought - - If you think a CCR is safer than OC, then why carry OC for bailout?
(devil’s advocate mode on)

Because it’s cheaper than a BO RB? A bailout machine would require double the investment in purchase, maintenance, training, proficiency, etc. For many, that‘d be an overkill. Besides, the technology is not quite there yet. But it’s doable and people do it, for the really big dives

Yeah, Richard Harris does a redundant rebreather when diving the Pearse Resurgence. It's totally doable, and been done before, just is very very expensive and for most projects it's overkill.
