Curt We fill our bottles in the hood. They are emptied into a vented flammable cabinet that contains a 55 gallon drum. You know you can do your own chemical badges for both xylene and formalin. I like to run a couple TWA (8 hour) exposures and then I badge a lot of STEL (15 minutes) exposures on what I think are worse case scenarios or where I think individuals have exposure for a short period of time, like changing the tissue processor, or loading the tissue processor, changing the stainer, manually coverslipping, grossing in tissues, etc.
If you are a small business OSHA has support services. They will come to your lab and perform an audit and review your safety practices (non punitive) and give you a report where they think you can improve. It was helpful to us. Liz Elizabeth A.

I think I've got some decent leads but I have another quick question, does any change the processor bottles, formalin, alcohols, xylem/subs, inside a ventilated hood?
