I haven't seen any data on how nasty glass wool is for your lungs, but
given the fact that much insolation is fiberglass and fiberglass has been
used in fabrication for many years, I would expect there to be a lot of
studies out there on just how bad it is.

Another point, from what I understand, you have to create fine particles of
asbestos or glass wool in order for them to enter into your lungs.  I'm not
sure how the glass wool is being used in the original message, but the
glass wool that I have used was in a form that would not be easily
converted into fine particles and aerosols.

Working with glass wool  can get itchy though.
