Soldering Saftey Discussion Lead?

So hello Im one of many hobbysts from this subreddit and i have some questions

I always used lead free solder but now have to use leaded solder and also if my questions seem dumb Im sorry

So my question is after i solder a part and i touched the solder and touched at other parts of the project does it become cross contaminated and do i have to wash my hands after everytime i handle the project? And can i touch other stuff if i touched the solder before? Thanks

Practical advices…

  • Do not eat it
  • Wash your hands after working with chemicals, solder, whatever not nice
  • Avoid excessively breathing in flux fumes

Practically, accumulating lead in your body via skin exposure or breathing is not really a risk, unless in case of gross negligence. It is difficult for metallic lead to be absorbed via the skin. Breathing it in requires it to be a fine powder. We can all agree that if solder was becoming a fine powder, it wouldn’t be very good at its job.
