[Histonet] Fume hood

[Walter Benton]

Brandi,
 
I have been through several renovations and highly recommend that you get a hood that exhaust outside. Depending upon what applications you plan to carry out under the hood, filters may not do the trick. It is also important to have someone from your facilities or engineering department conduct an air exchange analysis to make sure that you have proper airflow and exchanges within the room, since the two operations are being combined. I would also recommend that you have your area monitored for air quality while performing the various tasks that you perform now in you current configuration to see if you are OSHA compliant or whatever regulatory body you wish to follow. Downdraft ventilation is great for Xylene, because Xylene vapor is heavier than air, thus the reason those systems work well. Feel free to reach out if you have any other questions.

Hello,

Our hospital is doing some renovation and we need to look into new fume
hoods for our new location.  Currently we have one fume hood over our
grossing area, and one fume hood in our coverslipping area (two different
rooms).  The hospital wants to put our grossing room and histo/cyto rooms
together.  I am still going to need two separate hoods.  Does anyone have
any experience/knowledge/input about fume hoods?  I'm trying to look into
the ductless ones, although I imagine changing the filters will end up being
more expensive over time (I have no idea what would be involved in running a
duct/vent).  Also I have seen a benchtop downdraft type that sucks the air
down, and does not have a top.  It is advertised as being good for xylene.
Does anyone use this in their coverslipping area?  Any input would be
greatly appreciated.  I'm pretty clueless on the whole issue.  I want to
make sure that what I get will be safe for me and my coworker as we will be
spending most of our day in this room.  Any input is appreciated!  Thank
You!
