OK.... since you asked.. :-) http://www.peakantifreeze.com/pdf/msds-peak_rv_marine.pdf
http://en.wikipedia.org/wiki/Propylene_glycol The good thing is that there is a lot to read ... the bad is that the results say everything from the vapors are good to breath (seriously) to not so good to breath and can cause irritation. Propylene Glycol has been used for fog generation in stage productions and it is also used in Cigar Humidors.. (go figure..) along with a bunch of other things. Generally, none of this stuff is good to inhale. Lungs are designed to inhale air, not oil mist or antifreeze mist, etc. If you are inhaling the mist of any of these coolants, it is not a good thing. Still, this stuff might be better than the alternatives. Pick your poison.. Dave On 11/19/2010 10:34 AM, Kent A.
