Fellow wetbench users,
A few people have been using hot plates to temporarily store teflon beakers full of chemicals, with the blue paper label on the hot plate underneath.
That seems ill-advised. All it takes is for someone to accidently turn on the wrong hot plate, or do it without looking, and now there's a softening teflon beaker full of HF with a paper fire underneath. Then the smoke might set off alarms, etc etc.
I recommend only quartz or pyrex beakers on the hotplates and putting the label on the deck next to it, weighted to keep from blowing into the hotplate area.
