Re: safety - pcb dust hazard

Ballendo,

I have inhaled board dust and solder fumes, I have handled solder
till my fingers turned black and ingested solder by the pound by
biting it. I have used the squeezings from my soldering iron sponge
to flavor my coffee and have used heatsink compound instead of
mayonnaise on my sandwitches. I even have pickled eggs in used board
rinse carbon tetrachloride (when it was still legal). I can say with
absolute assurance it had no, assurance it had no, absolute it had
assurance no,...ah, effect on me!
