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.
