What percentage of lead gets washed off the fingers of a typical human after handling lead solder?
What percentage of lead gets washed off the fingers of a typical human after handling lead solder?
Does anyone know for reals? Is it like leaded gasoline; the more you use it, the less it seems to matter? /s
You're viewing a single thread.
Here's the relevant safety guides from Stanford and MIT.
In short, if you do a lot of soldering, there are long-term occupational hazards from both lead oxides and rosin. Both guides agree that the main hazards are the fumes (workstation should have a fume extractor or suitable filter) and residue on your hands (wash hands with soap and water before eating).
I couldn't find any numbers on how much material is removed by washing, but every reference emphasized that soap and water are vitally important.
Nearly every activity should be preceded by and followed by a good handwashing. Keeps you well.
note this is good normally but terrible advice if you have ocd. idk what everyone else’s experience is like but i got so obsessive over handwashing that my skin started to slough off of my hands from how frequently i began to do it. turns out that what constitutes an activity versus a moment is really hard to tell when you’re mentally ill af. no good.
Well yes, for someone with OCD there are a plethora of behaviors that aren’t the same for them as for ordinary people. I think that would go without saying.
Lots of conjecture and misunderstanding in the other comments. Thanks for posting actual sources.
