If the fumes are pretty strong, that tells me that there is not an adquate 
fume hood, or the filter has not been changed for a while, for the tasks 
being done with xylene.  We have one for the stainer and one for the 
coverslipping area.  I can see there would be a problem when disposing 
xylene in the drum or placing it in a recycler.  There are hydrocarbon 
filters available for half-face respirators in Lab Safety Supply catalogs.  
Do you have the phone number for this business?  I'm at home - can't give it 
to you now....
