Most electrolytic caps, both solid and wet are carcinogenic when vaporized. Even epoxy and PCV fumes. Consider this. The chlorine gas from vaporized PVC cables on 3 Mile Island were more toxic than the radiation levels.
Wet mercury is not as toxic as dissolved in water and a vaporized thermometer can kill thousands in a closed room. but not easily done.
Consult MSDS from manufacturers process.
Ok the situation is this:
The capacitors are vishay ETPW6N107016K and the datasheet is here
https://sklep.hfo.pl/upload/etpw.pdf
I accidentally connected one in reverse polarity and the capacitor exploded in the laboratory and then a very stinky red smoke came out of it.
The external body of the capacitor became black up to the middle. These capacitors have a protective fire resign, it may be that this resign burned out up to the middle. The capacitor itself did not explode apart, it was half black.
I avoided breathing the red smoke and I immediately opened up the windows, but the smell was there for more than two hours. I was not in there of course, but even so, I could barely smell the stink all over the rest of the house with the windows open.
Since I need to clean the laboratory I need to know the next things.
Are the materials used in such tantalum capacitors considerably toxic?
I find that tantalum is not highly toxic, but I do not know about the other materials.
As I said, I took precautions, I did not directly breathe the smoke in any means. It was just this smell afterwards.
I see some black smoke in the electronics nearby the failed tantalum capacitor, do you think this is toxic?
Please tell me if you know how to clear the bench area near the explosion, is it enough to use gloves and clean the bench using an ordinary house chemical cleaner?
Or do I need to do something else to avoid exposure for potential toxic materials?
A failed Hg lamp was hard to clean, but I do not think this situation with the capacitor is so toxic, since I did not directly breathe it.
Another time a small JFET failed and the resign stink like the capacitor, for a long time.
