We look straight on to a large steel-frame shed-like barn. It is being converted into a row of houses. The team came at the weekend and removed the existing "asbestos" roof. It comprised large light-coloured corrugated panels which I suspect are actually asbestos/cement. The process was impressively quick, there was as far as I could see no preparation like covering or wetting the roof. What surprised me though was that the removers did not wear any protective gear, no overalls or masks. Is that normal? Is the risk from the asbestos so low that all you need is careful handling?
