<P>PROBLEM TO BE SOLVED: To provide a sheet material for protection capable of being discarded by a simple procedure and to reduce a cost for disposal. <P>SOLUTION: A protecting ware 1 is obtained by forming from a triply laminated sheet material comprising a film layer 2 composed of a shielding film which can be melted by water and non-woven fabric layers 3 and 4 capable of being melted by water, which are arranged on the both surfaces of the film layer 2. When the ware used in a work of removing asbestos, etc. is discarded, the ware is introduced in a melting vessel filled with water, which is kept at a predetermined temperature and installed in the working site, whereby the ware is melted and drained, without using burying treatment which has conventionally been used. <P>COPYRIGHT: (C)2009,JPO&INPIT |
