Right up to about 5-6 years ago when we went all digital. Trust me I'll never go back no matter what anyone croons about the joys of the good old days being in the darkroom! Hey I loved it, it was my quiet time of true silence! Relaxing accept when making 16X20 fine art prints.... lots of tension during those times with absolutely no one ever saying a word! Total silence and mental concentration on the print making! A peep from anyone and they were out & gone! During the 57 years I never used gloves, occasionally tongs, but you can't soup 25 prints at one batch flipping prints over and over with tongs... Hands only! My record for souping prints in one batch? 55 prints dropped into the tray one right after the other by an assistant while I was flipping one print after the other in the chemicals. Then through the other trays to washer. My good fortune? I never experienced any hand or finger nail staining. As far as I know from lung x-rays during other conditions, no damage or any other chemical influence inside the lungs has ever been picked up. By the same token a couple of my buddies, now long gone due to lung cancer or other deadly lung maladies, there was a question if their deaths were due to long time darkroom mixing chemicals and hands in the wet trays. Generally pasted off with, "Naw that kind of stuff never bothers anyone. He was a smoker and died from that!" However? Did it? Was it maybe the chemicals? When I was developing prints as soon as I finished I always washed my hands in the stop bath, acetic acid & water. Then do the same thing in the fixer tray.... Followed by a good water washing. Did that or was that why I didn't have any staining as many others did? Or other bodily influences? I'm glad digital came along when it finally did, although it was 45 years too late for what it could of done during my career.
