This is exactly what I did when I designed our new facilities.  I built a
flame-resistant room which is well-ventilated directly to the outside.  The
ventilation unit is adjustable for varying amounts of cubic feet per minute
air exchange.  This unit is always on.  There is a special cabinet for
flammable chemicals, acid-resistant bench tops for the tissue processors and
multiple, adjustable shelves for slide drying in this room.  The solid wood
passage door is always closed.  I also built a fume hood directly on the
other side of one of these walls and placed a blower unit (from an old,
charcoal bench-top fume hood) through the wall.  This is where we coverslip.
When the blower is on, it sucks away all of the xylene-laden air into the
vented room which, in turn, is vented directly to the outside.  There is
never any xylene fumes in the lab.  On our main homepage, there's a link to
photos of our new lab.  Here, you will see the ventilated room as well as
the coverslipping fume hood on the other side of the ventilated room.

I hope this email finds everyone well,
 
I have the opportunity to do some redesigning of our laboratory space.  I
would like some feedback from some of the larger labs as to whether they
have a separate room for their tissue processors and/or flammable storage.
If so, how is it separate from the main laboratory working space...wall,
door, both?
Any feedback would be appreciated.
