My OPINION, as someone that concerns myself with both battery and fire safety, I applaud the OPās thread question.
I think a decent part of the equation is ācommon senseā, which we learn is not really common.
For instance, since I vape mostly alone, my considerations are far different then someone with a family, kids, pets etc.
I reached over my hot CH DCup rig, similar to my CH B1, on a stand, got a quick burn, have been much more aware since then and burn free. But, itās smart to look ahead, when you may be tired, drinking, other meds/drugs, whatever, then get high/medicated, the chances of a hot burn go up for me or anyone, but Iām willing to risk it without adding any heat shields, or depriving myself of a HOT heavy hitter device, and some manufacturers do sell add on heat shield accessories.
We obviously know a battery operated device like a Mighty isnāt going to burn anyone, but the OP specifically asked about ādesktop heavyā, and is concerned with other users well being, that maybe new and inexperienced, or was not warned in advance. While not applicable to my current needs, the insulated wooden log style vapes seem to be a top contender as a solution for the OP. Personally, Iāve never owned or used a log vape, so Iām just going with my own common sense.
FUNNY STORY TIME, as related to not warning someone before sharing a vape.
Work friend came over years ago, as I was getting into bubble hash at the time and concentrates. He was a heavy joint smoker. I forgot to tell him, what I had learned.... that you donāt need to hold the hit in, like a joint to get the results. Well, itās funny now I guess, but he took a huge, fresh hit, and I watched him hold it in for what seemed like forever, but I was too late to react, I was baked myself. Well.... I thought he was going to die, he was almost choking to death, and turned red and sweating. Thankfully, he survived, but went back to joints.
So just like my first vape device skin burn, I LEARNED a valuable lesson, as did my friend....
