Subject: Dry Erase Markers
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.
Thanks,
