> Because there is no safe level of exposure to asbestos. 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.
