  • I agree. As a young lab assistant back in the 1970s, I regularly used my fingers to smear mercury on the copper tails of standard resistors, (class S) to ensure good contact when they were placed in the mercury filled connecting cups. It was the norm in those days, I’m 66 now and as far as I know, do not have mercury poisoning. In adjacent labs you could enjoy such things as the fumes from hot CK wax, perchloroethylene, Propan-2-ol, and trichloroethylene. When using the latter, (Trico?) someone working at the next bench might casually warn you not to smoke, as inhaling the fumes through the cigarette generated Phosgene gas! Regards

No public wish lists :(
