For example, in the case of dismantling the side slate 3, the lower injection module 3100 is driven because asbestos scattering does not occur excessively in the area where the lower injection module 3100 and the lower detection sensor 5100 are provided. By controlling the driving to stop or operate by lowering the injection intensity, it is possible to efficiently drive the injection unit 3000 . In addition, when the side slate 3 is dismantled, the central detection sensor 5200 provided on one side detects the excessively generated asbestos scattering, so that the injection control unit 6000 sprays the side injection module 3200 provided in the corresponding area. can be increased to ensure efficient wetting operation.

In addition, the worker who has completed the dismantling of the slate 3 using the above-described working device 1 needs to wash his or her body for asbestos removal and cleaning. There is a risk that the attached asbestos powder is separated and dispersed in the air.

Therefore, using the spraying unit provided in the working device 1, the shower booth unit 7000 can be additionally provided to prevent the worker from being dispersed to the outside while washing the asbestos powder on his or her body. do.

The shower booth unit 7000 is provided at the lower outer side of the central frame 1600, and is normally provided at the lower end of the outer surface of the central frame 1600 in a folded state, and after the dismantling operation is completed, the operator is folded into the central frame 1600.
