<p>A method for removing a tube (6) containing asbestos from a building structure in dust-free manner comprises the steps of: (a) connecting a vacuum cleaner (25) to the tube (6); (b) wrapping the tube (6) over the whole free length thereof with dustproof foil (7,14) material and adhering this foil material dust-tightly to the tube; (c) choosing a severing zone (8) where the tube (6) has to be cut through such that a tube part defined by the relevant severing zone (8) and another zone where the tube can be detached from its environment, for instance a second severing zone (9), can be removed and disposed of; (d) adhering to the tube (6) around each severing zone (8,9) a severing sleeve (10,11) comprising an envelope filled with a sticky material (15) such that the severing sleeve (10,11) is connected dust-tightly to the tube above (6) and below each severing zone; (e) after step (a), cutting wholly through the tube (6) and the severing sleeve (10,11) in each severing zone (8,9) and removing each tube part between two cut-through severing zones. <IMAGE></p> |
