Re: xylene substitutes revisited
you must also take into consideration the
humidity in Ft. Lauderdale. Xylene can handle exposure to some water
without breaking down. Xylene substitutes often do not have the
capability to absorb water. Here in San Antonio, especially this time of
year, we have a high humidity level in the lab even though we have good
temperature control. When I tried to use a xylene substitute, we had to
add extra dishes and longer times to our staining because the paraffin wasn't
dissolving completely. This reeked havoc with our immunos.
I monitor the exposure
limits every six months. We have never registered over 10 ppm over an 8
hour time (OSHA's current limit is 100 ppm). I've purchased nitrile gloves
that do not break down as fast when handling xylene (we don't have an automatic
coverslipper. My techs think that I'm the automatic
Every tech that I have
hired, I gave them the MSDS book and told them to look specifically at xylene,
formalin and glacial acetic acid and to tell me if they have a problem with any
of these chemicals. So far, everyone is okay with it.

Subject: xylene substitutes
Good morning everyone. Our safety committee is all set to switch us to a
xylene substitute. In order to head them off at the pass, I'd like any info
you kind people can provide concerning the impact xylene sub's would have on
IPX as well as on routine tissue preparation; processing, staining, special
stains, well you know, the whole nine yards!
Thanks so much for taking the time to read this email....
