Drew, I never said anything near what you are suggesting. I did say that allergic reactions to common (and darkroom) irritants are in the minority among the people that I know. The majority are not having allergic reactions to anything. AAMOF, I am somewhat allergic to pollen in the spring, but not to photographic chemistry of any sort. So, I said that reactions vary.
I myself wear rubber gloves, safety glasses and a lab coat when in the darkroom. I've said that before and I'll say it again. That's because you probably missed the fact that I have said - "WHY TAKE CHANCES". After all, I wear a set belt in my car too!
