When I solder, I have a fan that blows the fumes away from my face, and I always wash my hands after. If you do these things when you only occasionally solder, then you should be fine....Nice decision to go lead-free, though! Lead-free solder is usually harder and more dense, so I suggest turning up the soldering temperature to 350* F. If you don't have a variable temperature soldering station, I suggest buying another iron that is higher in temperature. Good luck with all of your soldering!
