DEVICE FOR CAPTURING THE SOURCE OF FIBROUS AEROSOLS OF ASBESTOS BASED ON DYNAMIC CONFINEMENT

摘要

The present invention relates to a method for collecting and confining contaminated particles emitted in a direction of emission, comprising: - the static confinement (S1) of a volume above a surface to be treated; the suction (S5) of the contaminated particles, the suction force having a collinear direction or coaxial with the emission direction. The present invention also relates to a containment device for the collection of contaminated particles and a surfacing and suction assembly comprising an abrasive disc grinding machine and such a device.
