I'm new to PCB soldering. I just bought a cheap soldering iron, solder wire and flux to try something. I have no previous experience with soldering.
I'm well aware of the potential risks of prolonged exposure to flux fumes, and I have already taken precautions to avoid it.
I was all excited and ready to start soldering, when I saw this on the flux box:
I'm OK with not putting that into my eyes and not tossing it into the waters, but why does it say "CAUSES SEVERE SKIN BURNS"?
All the dudes on YouTube that I saw soldering touched rosin with their bare hands.
While that doesn't necessarily means it is a safe practice, it surely didn't cause severe skin burns! I would rate something as severely burning if it burns like sulfuric acid, for example.
The only explanation I came up with was that maybe this product is made of really cheap dangerous stuff instead of rosin.
The product is this:
However, looking online I saw the same warnings even on boxes clearly marked as containing rosin flux.
If all those people on YouTube can handle this stuff barehanded, I'm clearly overreacting.
So I ask you, why is this stuff depicted as extremely dangerous on the box?
- Can I safely touch it?
- Are those warnings put on the box only for legal reasons?
- Are rosin based and different fluxes more or less dangerous?
