A cocktail in the shaker

I agree with you, BUT do not try this on an Atlantis or Dolphin. CLs are backmounted, and the OPvalve is right behind the divers head. So to drain a cocktail one would be head down, and the cocktail would go right down the hose and into the mouth.
Some years ago there was a Dräger rebreather mailing list, and one of the members got a cocktail, head down in the water, trying to dump water from the OPV.
The unit can handle some water in both CLs, but it is not designed to dump it.
In my particular case all the water was in the scrubber and the inhale CL. So going head down, would have sent ALL of the caustic water right down the inhalehose !!!

That will be a ,25 liter bottle in metric

. So you bring the coke under water ?

BTW glad you made it through your caustic experience !

Ouch! Glad you didn't drink the stuff.. it's nasty, take my word for it.

Uh.. I took the hit on a back-mount, doing a vertical dive (we dive bomb). Thankfully in a pool, thankfully only 4' (1 MSW) down- & Tom Mount saved my life. The cocktail skipped the trachea & went right to the larynx, which doesn't open on it's own when badly traumatized for about 5 minutes. Tom used acupressure, & I became an instant believer in it, especialy as I wasn't able to breathe when I got to the side of the pool.

It was a "user error" incident on the Titan- I didn't realize I was taking on water for 4 hours (I didn't manage to shut the DSV completely during drills- dumb, dumb, dumb).

I agree with you completely- ALWAYS check with the manufacturer/know your rig- with certain back mounts, the old Dolphin Draegers, and other types of CCRS/SCCRs you can get in more trouble trying to clear the CLs than dealing with the water & doing your best not to let it turn into milk.

I definitely carry Coke- even a mild cocktail stays actively eating into membranes until it is effectively neutralized, & I'd rather neutralize immediately than go through deco knowing my throat will be sore as hell for the next few weeks. Mind you, it's a tiny bottle, as I'm a tiny diver- not much place-as in no place- to put a good-sized sports bottle. :-)

--Thanks, by the way. I'm glad I made it through too, & I don't reccommend it as a learning experience! LOL
