We're having a discussion as to whether using a fume hood for special stains
should be required or only desired (ie, personal choice). I know many
histolabs do not have fume hoods and do specials on the open bench but if a
fume hood is available, should it be used? It seems the regulatory agencies
are mute on this question as far as I can tell. Personally I think all
specials should be done in a hood.
