So far, most of the scenarios of emergencies can be mitigated by training, and practice.
One I'll put out there for discussion is mother nature, specifically down currents.
First an analogy: You're driving, hit a wet or icy patch and your car starts to skid. You can learn how to recover from one, and by applying the correct inputs you generally can. But sometimes - perhaps you over correct of the surface has less grip, what ever you do doesn't' work and you end up in a ditch.
In my diving area, down currents are frequent. I get hit by anywhere between 6 and 10 a year.
Most are insignificant, others not so.
You can mitigate the risk by being prepared. More gas than you'd usually carry having a switch of air in case you get sucked down below your MoD and being accustomed to serious currents in general. Or keeping away from sites that have them.
But there is no specific training nor practise you can engage in other than actually being in one
You're reliant on instinct in dealing what mother nature throws at you. I would suggest that all but the smallest ones, can be classed as an emergency.
While there are some articles written of how to get out of one, in my experience these methods only apply to a few types and then you are required to remember how to do it, muscle memory through training and practise just doesn't apply.
Even then it's more instinct and reaction more than deliberate thought.
And you have to accept that in rare occasions mother nature will beat you, whatever you do or try.
