Asbestos Cement Sheeting.

Good afternoon all,

                                  I have just visited a 1950s building to view it prior to estimating for a rewire. The owner has demolished some internal walls and the floor is covered in broken asbestos cement boarding, about 4 to 5mm approx I think. I advised him that only specialist companies can remove asbestos waste. Information websites describe this type of cement board as low risk as the asbestos fibres are trapped within the board. But the whole floor is covered in broken cement board. What is your opinion in working in that environment after the broken cement board has been removed? Would you? Or would you insist that only a licensed asbestos removal company should clear the site before any electrical work is undertaken?

 EDIT. I just found this.

  • I have worked in many lofts of domestic properties and other high level locations in buildings where dust may accumulate. In the lofts of older houses, say Victorian terraced town  houses the dust is worrying. The dust may not be asbestos but may be organic or inorganic. On many occasions I have been working in a dark loft space running cables, perhaps with just a torch or there is a narrow shaft of bright sunlight shining through a broken roof tile or slate, and when I moved the fibreglass thermal insulation, millions of tiny particles are moved into the air, and these can be clearly seen suspended in the air and illuminated in the shaft of light.  These tiny particles may be dead insect parts, glass fibre particles, dead leaves' parts, soot from old coal fire burning, particles from car brake pads/shoes, industrial pollution, or general "dust". I do not think that it is good to breath that stuff in. A dust mask is a good idea at least. When I was younger I did not use a dust mask as I found them uncomfortable and made my face sweaty, which held more dust. But now I can see the benefit.


    Regarding fibreglass,there may be immediate reaction to exposure, resulting in irritation to the eyes, nose and throat, while prolonged contact with the skin can lead to dermatitis. The long-term effects of the inhalation of fibreglass dust particles include breathing difficulties, asthma and decreased lung function.
