Don't see a problem with warning labels; I'd rather be told there's a risk and make my own mind up than be sold potentially harmful goods and discover the dangers myself. I like the Nanny State to mark dangerous bends in the road with big chevron signs that glow in the dark.
I think information is good. Guesswork, assumptions, 'common-sense', prejudice, beliefs, ignorant opinion and old-wives tales are lazy and risky.
Happens the State of California take a particularly tough line on hazardous materials, and the link on the label spotted by Michael is helpful in understanding that. Thanks to California, we know the Starrett product contains Lead, and being intelligent chaps we understand that's unlikely to matter in a workshop. Would matter if the product was much used by pregnant ladies, or small children chewed it. California don't guess who the end-user is; all products containing one or more of their list of hazardous materials must be labelled. Simples! – it's not assumed products are only bought by people who know their stuff.
Ignorance may be bliss, but knowledge is power. Presumably chaps who hate safety warnings never read instructions either. Not me! I find it's easier to assemble flat-pack furniture by following the manufacturers comic book guide rather than doing it my way. And I always read the small print in contracts before signing anything!
