An apparatus for removing surface material such as contaminated textures including asbestos and the like from wall and ceiling structures, while preventing the removed material from escaping into the ambient environment. The apparatus provides a portable shroud (17, 13, 56) enclosing a material removal member (28, 65, 75) which could be a shredding head or an emitter (44) of sonic, ultra sonic or ultraphonic signals. A liquid or coagulant spray manifold (58) operates in close proximity to the material remover and is utilized to capture and retain air borne microscopic particles. The material remover and spray manifold are mounted on a power carrier (20, 24, 27) which is adapted to reciprocally move these elements within the shroud and above a material receiving hopper (73). A vacuum recovery system (16, 40, 71) acts in cooperation with the hopper to retrieve and retain for disposal the removed surface material. |
