The Toxic effects of many substances were unknown back in the 'good old days of spark transmitters', and where ir-t was known, it was "unmanly" to worry or complain about such things. Reporting health problems most likely got you fired.

In the 'good old days of spark transmitters' it was common for rotor or
even the rotor and stationary electrodes of the rotary gap to be made
of cast zinc and I don't remember reading of any health problems or any
precautions. Besides, you get a nice blue spark.

may have had different results, but I thought I'd
mention it.
