We recently have a lab doing Hematoxylin and Eosin (H&E) staining contacted us to add a shelf in the fume hood to “store” the histology troughs (which includes ethanols at different concentrations, xylene, hemotoxylin, eosin).
The PI insisted this is a common procedure in histology labs and the solely purpose of this shelf is for this experiment.
From EHS and Fire code side, No chemical storage in fume hood (only notable exception being some toxic gases in lecture bottles). In code this applies to flammable liquids.
Any experience or comment can share with me regarding the best practice for this case. Thank you very much.
