PROBLEM TO BE SOLVED: To provide a removal method of an asbestos-containing coating material excellent in a work environment in a work area.SOLUTION: In the removal method of an asbestos-containing coating material applied on a wall surface 1, a removal work area A for removing the asbestos-containing coating material (asbestos-containing paint 2) is partitioned from the exterior by being covered with an airtight member 4, and the interior of the removal work area A is put into a negative pressure state. Then, by using a separation-suction device 10 having a nozzle head 20 for spraying an abrasive 11 on a removal target object and recovering the removal target object separated by the abrasive 11, the asbestos-containing coating material is separated from a removal surface of the asbestos-containing coating material by spraying the abrasive 11 on the asbestos-containing coating material in a state that the nozzle head 20 is pushed against the removal surface of the asbestos-containing coating material to partition a spraying space of the abrasive 11 and a recovery space of a scattering object from the exterior, and the abrasive 11 and the separated asbestos-containing coating material are recovered. |
