But no matter how you try to regulate it, students will always try to get around rules as they already do on items like hotplates and toaster ovens etc. The only good solution is to provide common areas where students can cook or charge these sorts of items (unless you just ban them completely). Still won’t stop people from prohibited stuff like lighting candles etc. but at least you can create a safety-forward environment.

When I was a college freshman, a student in my dorm lit his Hanukah candles before going to bed. He looked around the room and thought to himself “I should be careful, where would be the safest place to put a candle” in this literal cinderblock box of a double room. He thought to himself “Ah, yes, on top of the mini cube fridge - nice metal surface, no papers” and went to bed. I assume the idea of sleeping with candles being a Bad Idea wasn’t considered in his risk assessment.  So he went to bad, failing to recognize the fridge was in front of a window with 25+ year old curtains that were made of something pretty much akin to burlap. He fell asleep, the curtains went up like flash paper, and he slept through it. A neighboring student broke down his door and dragged him out with only minor injuries. I remember evacuating the dorm via a stairwell in his hallway, unaware that any of this was a going on, assuming it was yet another fire drill, when we smelled the smoke on the stairs. Yikes.
