Abstract
A method for removing asbestos-containing materials from substrates including a nozzle assembly for directing streams of pressurized steam to penetrate asbestos-containing material sufficiently to loosen binders therein so that the material can be easily dislodged from the substrate by a second stream of higher pressure steam. The nozzle assembly also includes a suction device having an inlet opening arranged adjacent steam ejection nozzles to draw-in asbestos particles and fibers entrained by the steam directed onto the asbestos-containing materials.
Claims10
A method of removing bound asbestos-containing materials from substrates, comprising the steps of directing at least one stream of low pressure steam to penetrate asbestos-containing material sufficiently to loosen binders therein so that the material can be easily dislodged from a substrate, and directing a controlled stream of higher pressure steam against the asbestos-containing material for dislodging the same from the substrate.
A method for removing bound asbestos-containing materials from substrates, said method comprising the following steps:
- directing at least one stream of low pressure steam to penetrate asbestos-containing material sufficiently to loosen binders in the material so that the material can be easily dislodged from a substrate;
- then, directing a controlled stream of higher pressure heated fluid against the asbestos-containing material for dislodging the material from the substrate;
- and
- by suction, drawing-in asbestos particles and fibers entrained by the higher pressure fluid that is directed onto the asbestos-containing material.
A method for removing bound asbestos-containing materials from substrates, said method comprising the steps of:
- directing at least one stream of pressurized heated fluid to penetrate asbestos-containing material sufficiently to loosen binders in the material so that the material can be easily dislodged from a substrate to which said substrate is bound;
- by suction, drawing asbestos particles and fibers entrained by the pressurized heated fluid into a suction inlet means and ejecting a portion of the pressurized heated fluid directly into the suction inlet to assist the suction to prevent clogging of the suction inlet means.
