PROBLEM TO BE SOLVED: To provide a method for removing a spraying material containing asbestos, by which working time can be reduced by simple work and a spraying material containing asbestos can be surely removed even in a narrow working space and when a shape of a base material is complicated. SOLUTION: An acid fluid 3 is injected near a bonded surface T between the spraying material 2 and the base material 1 by means of a handheld injector 4; so as to dissolve the spraying material 2 by a reaction with the acid fluid 3, and to be spontaneously dropped while being separated. By taking the dropped spraying-material 2 away, the spraying material 2 sprayed on the surface of the base material 1 is removed. COPYRIGHT: (C)2010,JPO&INPIT |
