ABSTRACT:
Apparatus for removing asbestos material from horizontally arranged pipes in a linear, T-shaped or L-shaped configuration includes a rigid box-like device having a rectangular bottom wall and four side wall sections which extend upwardly from peripheral edges of the bottom wall so as to define a continuous side wall and so as to define an enclosure therebetween, the side wall having an upper edge with two pair of opposing recesses formed orthogonally with respect to each other in the upper edge of the continuous side wall for receiving the pipes, the upper end of the box-like device defined by the upper edge of the continuous side wall being open; a plurality of glove apertures formed in two opposing side walls, a glove associated with each glove aperture, each glove connected to the side wall in sealing relation to the respective glove aperture and extending into the enclosure; two suction apertures formed in the remaining side walls for connection to a negative pressure system to supply negative pressure to the enclosure; a filter in covering relation to each suction aperture to trap any airborne asbestos material; and a removal aperture formed in the bottom wall for connection to a container device so as to remove bulky portions of the asbestos material which have been removed from the pipes.
