Subject: doubles isolation drill
What is the standard drill for practicing and actual emergency isolation
of manifolded, isolated doubles?

I mean, obviously, if the reg in your mouth goes to uncontrollable
free-flow, you spit it out, switch to the other, and shut down the right
post.

But say you blow a tank o-ring or one first stage develops severe
problems.  You might not know which tank has the problem right away, as
even the bad side reg might continue to deliver air for a while.

So, I'm guessing the drill is:

1. If you can breathe, but hear catastrophic failure, isolate first
2. Continue to breathe off of reg until it quits, if it's going to do so
3. Check spg's to see which side has the problem, change regs
accordingly if necessary

Anyway, this is just put up for discussion.  What do people use as a
practice drill, and what different scenarios do you practice?
