It's possible that they will claim the health hazard isn't the snakes themselves, but all the heating elements and electrical plugs. When I lived in dorms (a VERY long time ago ) they were older buildings and concern about overloading the circuits with too many small appliances was a very real one. We weren't allowed to have a microwave or blenders or coffee makers or anything with a heating element in it...at the risk of overloading circuits OR burning down the building with a coffee pot that was left on.
