Both proved most useful for the investigations we have carried out which, as you have noted, confirm that the tiles are not in any way dangerous to health. Physical testing of the tile by an independent occupational health consultant shows that scraping of the edges with a knife, grinding of small pieces in a mortar and pestle and removing of dust from the back of the tile failed to produce any asbestos fibres whatsoever. This confirmed the view that if any asbestos were present, its content would be low, it would be occluded by the binders used during heat treatment in the manufacture and under normal conditions, it would be a very remote possibility that any asbestos dust or fibres could be released to the air. As a corollary, to again release any asbestos it would be necessary to destroy those binders by some drastic treatment such as heating in a furnace at high temperatures . Hence it is clear that, assuming the tiles were laid on a clean floor or board, any dust which is now there will be normal household dust unavoidably accumulated over the years. It can be removed by vacuuming in the normal way or dampened with water and wiped up. In removing the tiles we suggest that the tiles be lifted using a tile lifter with a spade-like action or, if it is practicable, to remove and replace both the tiles and the board on which they are laid. Of course, it would be quite acceptable to leave them there and cover the tiles with the new floor covering. I do hope this explanation will allay any concerns you may have and wish you well with your extensions. it* 1 4 Yours faithfully, \
