There are oodles (aka many) things in soaps that lead loves to grab onto and make stable compounds. If people follow the prescribed practices for correctly handling solder/lead and use proper hand washing practices, then the need to hand wipes is not necessary.

Was I aware of any industry studies on the efficiency of hand wipes marketed at removing lead residues, presumably from contact with cored wire solder? I was not aware of any. I am always instantly suspicious of ANYTHING that marketers touch. I am of the opinion that good old fashioned hand washing with soap and water is as effective as anything, but there are areas here where we are pretty sure our operators go straight from the bench to lunch without that step. So, I turn to my favorite source of information. 1. Are you aware of any industrial hygiene studies regarding transferrence of lead to the hand, and/or the efficiency of "lead removal wipes" in removing residues. 2. In your facilities, do you use these kinds of wipes? 3. If not, what measures do you normally use for operators cleaning hands to remove potentially harmful material? I will probably discuss this with our crackerjack metallurgist when he returns from travel tomorrow, but thought I would ask in the mean time. Doug Pauls
