Turning my valve on/off is one of my weekly drills and I don't find it arduous at all. But that was with a free flow in mind. With 83 seconds or whatever it takes for the tank to empty on an LP failure, I wasn't sure whether this kind of action would make much difference.
That's good, it an important consideration and a useful skill, even for single tank recreational divers.
Any 'inconveniences' to expect with folding over the hose? Like the hose exploding etc.?
And excuse my ignorance, but on a technical level, what is the difference with a HP hose jamming on and a 'failure' of this kind that will empty a tank so quickly? Is jamming on more likely sand etc. where this kind of failure is structural. Sorry if I'm asking dumb questions, but it's the only way I learn.

The original poster's failure COULD have been caused by a HP seat problem that allowed the IP (normally 125-145 psi depending on the reg) to go way too high and blew the hose apart but it's more likely the hose had a defect when it was made (as has already been stated). I'd still check my first stage IP to rule it out.
Folding the hose over is a viable option and won't cause any other failure provided the IP isn't running away.
