So, if you’d like a little education on why the comment you replied isn’t nearly as dramatic as you’ve made it out to be, pull up a chair. Both lead and mercury are pretty damn safe to handle as metals in your hand. Getting inside your body is where it becomes a problem, where it’s able to form different, body-soluble compounds and become toxic. Your skin is constantly pushing itself out, so lead residue on your hands isn’t going to have a route inside unless you have cuts or lick your fingers. And even then, the lifetime accumulation is really insignificant with this method for non-occupational handling.

Vapors are the immediate cause of concern for OP. Ingestion (eating lead paint, eating food that has ingested/leeched in lead) is where it becomes dangerous faster. If OP is diligently washing their hands but huffing all the fumes, the cleaning is entirely in vain. So yes, that’s why it’s important to make the above distinction in regards to Scenario A being nothing compared to B, C, or D: treating for A is worthless if the other 3 aren’t considered.
