RE: 'WHITE asbestos firms braced for ban' (Constriction News, November 27). I was surprised to see the quote from John Bridle: 'There is no health risk at all from white asbestos.'
I appreciate that white asbestos is less dangerous than the blue or brown types. I also accept that
asbestos-based slates are reasonable safe performing their intended function whilst on a roof.
The problem comes either when they are cut before being laid or when re-roofing occurs. In the latter case, the slates are usually dropped via a chute (or thrown) into a skip.
They tend to break releasing dust ... asbestos dust if I am not mistaken.
