Re: Use of quick freeze spray during frozen sectioning
The Histobath freezes the tissue very rapidly using Isopentane..it's great !!
As for the TB hazard..in our institution the techs do the frozens so a lot more people are exposed..I think that is why the issue came to light initially.
And if it makes you feel any better, WE care if the pathologists are exposed... :o)
Have a great day,

In the small pathology practices I work in, usually with cryostats 20 to 30
years old, the freezing spray is usually the only freezing method available.
Some of the older units don't even have the metal heat extractors, and
retrofits for these things don't work. I can't imagine what a Histobath might
be - we'll get it twenty years after its introduction, whenever that may have
been.
I agree that the freezing sprays are a real hazard to health because of the
possibility of spreading tuberculosis, but as long as only the pathologist is
exposed I don't think anybody out there much cares.
