Tom, I became senstized to butyl acrylate in graduate school after using it for about 3 years (with one year to go..). Just a small droplet landing on my hand or arm would cause the entire arm to turn bright red and swell up a bit. I ended up having to wear gloves (good idea anyway, and protective clothing when I used the stuff. The reaction was very specific, other acrylates didn't (and still don't) affect me. That was 26 years ago, I'm still senstive to the stuff. There were no other effects other than the reddening/ithcing of the skin and the slight swelling, nothing respiratory at all.
