I bought a couple boxes of disposable latex gloves at Sam's Club... I wear them whenever I use epoxy. This is mainly to just keep the stuff off of my hands, making clean up easier, but if you're concerned about health risks these should help. I also use a respirator (made to filter out paint fumes, pesticides, toxic dusts, etc.) when I cut or "Dremel" anything that's going to kick up lots of dust. If you're concerned about epoxy fumes, a respirator with the proper filter should help. I never tried mine with epoxy, but I wore it when I was mixing up some Bondo, which has very strong fumes, and I couldn't smell a thing...
