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.
