Possible hazard at WBGaAs and WBGeneral

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.  

Thanks,
Robin King/IBM
