30 years of inhaling lead, tin, and flux. Never did any harm, and I sometimes miss the smell. Down here everyone in every engineering department was conservative. Up north, many were union. Very different atmosphere.
In a former life I worked in mfg dental equipment; drills, etc. No lead solder or cadmium allowed near the patient’s mouth. Silver solder only.
I was a bit concerned about the beryllium oxide side effects that I inhaled years ago but all the solder fumes seems to have negated them. Yes, I was a chip off the ol’ 2-way radio comm tech father. Except when I graduated from tech school, transistors and computers were rapidly replacing all of Pop’s vacuum tube electronics-the big Weller solder guns were no longer needed. We used solder pens and other things as the technology advanced but I still miss the smell-about the only thing that smelled any better was Mom’s pound cake and burning hippies!
