Cy;
I assume you don't work in the chemical industry by your reaction to the
warning label.  While not to minimize dangers, you need to keep a certain
balance and understand that we live in a litigious society.  Have you ever
read an MSDS for acetone? Or an MSDS for normal resins that are used for
general purpose fiberglass that contain between 40% and 55% styrene?  For
years, if you have a wife/daughter that used hair spray, MC was used as the
solvent 'carrier' for the hair spray 'glue'.  It was used because it would
flash off in the distance between the nozzle and the head but get the 'glue'
out of the can.  So for years (up to about 4-5 years ago) nearly every
morning some women were getting a dose of MC.  I personally have worked with
the material for 20 years and prefer using it rather than acetone both for
its cleaning ability and the fact that it is not flammable.

If you look at an MSDS for MC, I think you will have a hard time finding one
that says that it is a known carcinogen.  It is suspected because in very
large doses rats have had an increase in tumors.

Above are some sites that describe MC.
