Per industrial hygiene: our recycler should be operating at RH 10-15%



Any suggestions for our lab would be helpful:  we are averaging 58% to
78%.  In addition to the HVAC system (new air handler) we run 2
dehumidifiers and a portable air conditioner in our lab to maintain the
current humidity levels.  We use Formula 83 xylene sub and with quite a
lot difficulty from April to September.  At our highest you could watch
the 100% ETOH change in front of our eyes, thus going thru a lot of
reagent.  We use H2Blu in the F83 to help absorb any moisture carry over
in the stain line and change/rotate F83/100%ETOH frequently, sometimes
several times a day.
