I work on scales. This morning I had to work in the pit under a truck scale, at a feed mill. Sitting on a wooden block, boots on with about 6 inches of mud, spiders everywhere, flying insects, mice, and the occasional rat running up to you on an I-beam to check you out. Smelled horrid. Right beside me, sitting on another wooden block (to keep it clean) was my PV. 2 hours of wiring and my PV lived with me the whole time.
The big question for me would be, where would I NOT vape? Pretty much nowhere. Maybe not during church, but everywhere else is fair game.
