Abstract: Apparatus for handling potentially dangerous materials by an operator, comprising a work head including a main body (2) having first and second work zones therein, the first and second work zones (15, 19) being arranged adjacent one another with a transfer opening (20) therebetween. The apparatus further includes a first access opening (17) for providing access to said first work zone by the operator from externally thereof and a second access opening (21) for providing access to the second work zone (19) by the operator from externally thereof. An air flow generator (85, 86) is provided for withdrawing air from said first work zone and the apparatus further includes liquid spray means (23) comprising a plurality of spray heads (27) arranged so that liquid spray therefrom forms a plurality of liquid barriers or curtains which at least partially surround the second work zone including liquid barriers or curtains across the transfer opening (20) and second access opening (21).

Abstract: Apparatus for handling potentially dangerous materials such as asbestos comprising a main body portion (3) having a work zone (5) therein into which, in use, the material can be placed. An opening (7) is provided to enable access to the work zone (5) from externally thereof. The apparatus further includes spray means (8) operatively mounted to the main body (3) and operatively connectible to a fluid source. The spray means (8) comprises a plurality of spray heads (8, 8A, 8B, 8C) arranged so as to form a plurality of fluid barriers or curtains which surround the work zone (5) and means (16) is provided for maintaining a pressure differential between said work zone and externally thereof when the apparatus is in use.
