Tbh, the thing about stills is only a big deal inside, unless you’re the one running the still and are close to it.

Outside? An explosion really isn’t going to fuck anything up. You get a big bang, some burning fuel, and that’s about it unless there’s a drought on. Inside, you can have more fumes built up, and the fire is likely going to spread to the building. So it’s more dangerous.

But meth production? Like previous comments said, that shit just keeps on giving well after whatever starts the process going wrong.

There’s really a massive gap in both danger and duration of the two kinds of fires.
