Re: "require" or "desire" fume hood for special stains?

From:Lesley Weston

If the stains, special or otherwise, include a clearing and mounting stage,
and also if they include deparaffinisation, then xylene or its almost
equally toxic substitutes are involved. So a hood is essential, however
loudly the financial department objects. When I first started doing EM,
years ago, I asked for use of a hood for the osmium stage. I was told by the
department's administrator that I could just wear goggles, and then I would
be safe.
