To the List: I am a high school and community college chemistry and physics teacher. Over the years I have developed a severe allergy to Expo dry erase markers. The original ones manufactured by Sanford Corporation. They contain methyl isobutyl ketone and n-butyl acetate plus pigment and resin. It seems to be the two chemicals that cause the allergic reaction as Expo 2 markers I can use okay. They contain ethanol and 2-propanol. I was wondering if anyone has had experience with this before and if anyone has any suggestions. I am on prednisone, double doses of Allegra 180 and double Zantac just to go to work everyday. The high school has recently removed all the original markers and replaced with Expo 2, but I still have trouble, although not as bad. How long do these chemicals "hang" in the air or ventilation systems? Any suggestions would be appreciated.
