I'm not especially worried to be honest. Between my job as an engineer and what I've learned so far as a sub-ohmer, I'm pretty comfortable vaping at those levels.
I recently retired half a dozen VTC5s, so I took them into work last week and deliberately vented three of them just because. The first two were a major disappointment; I hard shorted them with a piece of metal bridging the positive and negative ends. It took took a couple of minutes for them to actually pop, and even at that it was more of a fizzle. The third one I hooked up to an electrical test rig. It went off like a rocket, but then so would I if I had 415V and 32A shoved up my backside like the cell did.
TL;DR version: Mech mods and IMR batteries aren't the hand grenades they're made out to be. By the same token,
Risk is always relative.
