[Histonet] guidelines for using a microwave designated for food, but used to heat up histogel

[Charles Riley]

There is no direct CAP regulation regarding the use of microwaves
concerning food and chemical use.  However, ANP.29430 says that microwaves
used in the histology lab need to be under a fume hood to capture any
vented chemical fumes.   Also, I am not sure what the actual record is but
I am sure there is an OSHA regulation that is part of the Chemical exposure
regulations that states microwaves used in laboratories can not be used for
both food and chemical processing.
