I have been doing quite a bit of lathe work using a kool-mist this week

They spec sheet says it totally safe, but does anyone know something
different?
Maybe just the fact that I have been breathing a lot of water vapor
could make it easier to get sick?

I just saw an article on the subject, but can't
find it now. The gist was that there seemed to
be more asthma-like symptoms and complaints where
it was used. The problems were thought to be tramp
oil and mist out of ph specification rather than
uncontaminated fresh mist.
