While we are on the subject, I was told at one time that I was
probably suffering from the effects of multiple chemical exposure. (ahh,
maybe that is my problem) The route was mostly inhalation, with some skin
exposure. Although no one chemical was at a high level, the combination of
low levels seemed to create a problem. I was skeptical, but this info came
from an official inspector, and the changes we made cured my problems. So
especially if you deal in many processes, it is wise to limit exposure as
much as is practical, because even with what seems like reasonable care,
you can get nailed sometimes.

I just have to ask Dick, what does oxalic acid taste like?
