PURPOSE: A method for removing asbestos from a building is provided to naturally remove asbestos using the weight of steam since high temperature steam is continuously supplied the asbestos. CONSTITUTION: A method for removing asbestos from a building comprises following steps. The steam of 60~130°C is provided through a steam feeder(60) to an asbestos removal region(30), so an asbestos structure(20) is boiled by steam. Quick freezing refrigerant is sprayed on a wet asbestos structure through a quick freezing refrigerant sprayer(70), so the asbestos structure is frozen. The hot air is supplied to the frozen asbestos structure through a hot air dryer(80). The asbestos structure is built. The asbestos structure is repetitively steamed, frozen, and boiled, so the asbestos structure is cracked by contraction and expansion and is separated from a slab(10).
