And the question I have asked is where is the evidence that such small quantities are a risk? The UK links I have posted suggest otherwise. This is why I am asking.
I'm puzzled... are the US courts are saying "OMG Asbestos" rather than looking at safe levels? What if the same courts said "OMG 5G" ! This is why I am asking a genuine question.
From the above Reuters article "The World Health Organization and other authorities recognize no safe level of exposure to asbestos. While most people exposed never develop cancer, for some, even small amounts of asbestos are enough to trigger the disease years later."

I actually was at a landfill expansion project where a backhoe digging down through the trash hit some bags labeled asbestos. I’m glad it was raining. Also worked in a building with asbestos in the floor tiles. Fine when not disturbed, but anytime they had to remove them it was a production.
I feel like the risk is probably less than you think (the facilities people I worked with thought it was overkill for the tiles with a small % of asbestos). but its not zero. As someone who might have been exposed (was in a vacinity), its hard because you can never really know. Also there might have been other instances where exposure might have happened and you don't know (my high school was rebuilt recently because it wasn't 'up to code" when I was going there.
I think we are getting to the bottom of this :-)
The UK Health and Safety Executive state...
"The control limit for asbestos is 0.1 asbestos fibres per cubic centimetre of air (0.1 f/cm3). The control limit is not a 'safe' level and exposure from work activities involving asbestos must be reduced to as far below the control limit as possible."[1]
Maybe this is where the differences arise. The UK are comfortable with a minimum practical level where risks are very low, whereas the US state none at all.
Thank you for helping answer a question and not mindlessly clicking on down vote. HN is beginning to turn into Reddit rather than seeking inquisitive technical/scientific conversation.
The UK took its time but they did fully ban Asbestos in 1999.
That said, it is very much known that there are no safe levels of exposure. We know this from case data, but also pretty horrifically from workers who inadvertently gave their family members terminal illnesses later in life because they carried what would have at the time been considered fairly trivial amounts of loose dust home on their shoes/overalls/hair.
I've never heard of claimed talc-cancer links in the UK.
> A Reuters examination of many of those documents, as well as deposition and trial testimony, shows that from at least 1971 to the early 2000s, the company’s raw talc and finished powders sometimes tested positive for small amounts of asbestos, and that company executives, mine managers, scientists, doctors and lawyers fretted over the problem and how to address it while failing to disclose it to regulators or the public.
I think you're being downvoted for not RTFA, not for asking a question.
