At least the way I have used it, the end of the tube is only a few inches past the end of the microphone it is strapped to the side of. So you'd have to take the mic and stand with it to swallow half the tube. Safety is #1, or maybe #2 (we do huff solder fumes), so better safe than sorry I suppose.I think the tall box is the only type of effect I've never actually used. I'd be afraid of having one of my spasms and swallowing half the tubing
