Proposal
We could ask for a banner on Support for banners? that the mods could apply to both questions and answers that may contain blatant safety issues.
My example text (You can completely reword this; it's just an example.):
Warning! The practices or procedures in this post may have a serious risk of bodily harm. Only attempt these if you are professionally competent in this area. See General Safety Guidelines.
Note
(If you guys support this,) Before we post anything to Meta.SE, we should really hammer out the idea here. We only get one chance there and a half-baked idea will get shredded.
