Did State of California make the same warnings in things like "KFC fried chicken"??
I'm not kidding, but asking, because if they are so strict in Shure, also should be on things that are bad for prolonged exposure.
If they haven't outright banned KFC from operation in CA, no doubt, there's no less than 6 different bills that will try, and a dozen that have only narrowly escaped passing in the past...
...I mock CA lovingly....on the opposite coast we're starting to show more severe symptoms on the madness as well (the "sugary softdrink tax" comes to mind....which I have to laugh at considering the disconnect between the politicians and the planet Earth. What was the last softdrink you had that actually contained any sugar whatsoever? No, they all have corn syrup instead... So I'm wondering what softdrinks would be taxed? Presumably upscale sodas from small bottling companies, definitely not the majors.)
To follow the headphone warnings, I'm wondering how music is ever made in CA. You shouldn't use headphones, they're toxic. You shouldn't run speaker cables, they're toxic. You shouldn't buy CDs, they're toxic. You shouldn't buy digital downloads, the servers that provide them are made of toxic things. You can go to a live concert, but the concert shouldn't be amplified because the cabling, amps, and mixing boards are toxic. The musicians can play acoustic instruments....but the strings were probably treated with toxc substances that may or may not contain lead or mercury. The venue shouldn't be illuminated because the light bulbs are toxic. :) "Welcome to California: State animal? The Unicorn. It's real, we swear!" :)
It's one of those things that, the idea made sense, a product that contains potentially DANGEROUS levels of toxic substances should be labeled as such. Products that achieve dangerous levels of toxic substances on their own probably shouldn't be sold to begin with. But as-is an open ended labeling requirement makes the actual point of it meaningless. There are almost zero manufactured products that contain zero percent of anything at all toxic, which means virtually every manufactured product has to be labeled as toxic. And nobody actually reads or cares about the warning because it's the same warning they've seen on everything else they bought, so if they buy something that actually is packed with depleted uranium, they'll still be as oblivious to it as if it had no label at all.
