Bev,
Water is also a VOC! - Albeit under certain conditions :-)
Certainly it will kill you if you drink enough of it.
My message is to be VERY careful about how MSDS info is interpreted. One
needs to understand the test conditions that were used. Remember that as a
result of the savagery of Consequential Liability in the good ol' USofA, all
manufacturers have to cover their arses!
Another example I use, regards the term "Highly Flammable Flash
Point -1degC. Alcohol is lower but I rarely come across smokers who burst
into flames while having a drink! Know what I mean? :-)
Regards,
Graham Naisbitt
