Definitions

  • the present invention relates to an enclosure used for the decontamination of personnel who have been handling dangerous or toxic materials, one example being asbestos.
  • a multi-chamber enclosure comprising an external frame and a flexible cover suspended from and hanging within the frame, the cover including a first opening for providing access to and from a clean environment and a second opening for providing access to and from a hazardous environment, and at least one flexible partitioning wall which divides the enclosure into two or more chambers, said partitioning wall including an aperture therein for providing access between the chambers and two closure flaps overlapping said aperture, one closure flap being located on one side of the partitioning wall and the other flap being located on the other side of the partitioning wall.
  • the closure flap located downstream of the partitioning wall will move away from the wall whereas the flap located upstream of the partitioning wall will press even closer against the wall, thus providing a much greater resistance to air flow and hence allowing a greater negative pressure to be achieved within the enclosure.
  • closure flaps are freely suspended along their upper edges, so as to hang under gravity in closing positions with respect to the partition aperture when no air is being drawn through the enclosure.
  • Fig 1 is a perspective view of a frame forming part of the enclosure of the present invention.
  • Fig 2 is a perspective view of the enclosure of the present invention
  • Fig 3 is a perspective view of the interior of the enclosure, showing details of the partitioning walls and sealing flaps.
  • Fig 4 is a perspective view of the interior of the enclosure, showing an alternative arrangement of the partitioning wall and sealing flaps.
  • Fig 5 is a perspective view of the "dirty" end of the enclosure.
  • Fig 6 is a schematic view of the enclosure showing how the sealing flaps move under the action of air flow through the enclosure.
  • an enclosure 1 according to the present invention comprises an external rigid frame 2 formed by separate elements 25,26,27 and 28 which are assembled together as shown.
  • a flexible cover 30 of material which is impervious to contaminant is suspended within the frame by means of straps and buckles 31 and loops 32.
  • the cover 30 extends into flanges 30a at the base of the enclosure, these flanges being passed underneath the base members 25 of the frame to provide a seal between the enclosure and the floor.
  • a zipped opening 48 through which a person may enter or leave the enclosure, and at the other end of the enclosure there is provided for the same purpose a flap door 43 which is surrounded by a flange 42.
  • Flange 42 can be sealed to a hazardous working environment, this end of the enclosure thus being referred to as the "dirty" end.
  • a series of flexible partitioning walls 40,47 of the same material as the cover 30 provide separate compartments which communicate with each other via apertures 49 in the partitioning walls.
  • Two closure flaps 41a,41b are located one on either side of the aperture in each partitioning wall, the top of each flap being fixed to the "roof" portion of the cover 30 so as to hang freely therefrom.

Abstract

Enceinte (1) à chambres multiples comprenant un cadre externe (2) et une couverture souple (30) suspendue au cadre à l'intérieur duquel elle pend, la couverture comprenant une première ouverture (48) destinée à assurer l'accès à un environnement propre et hors de celui-ci, une seconde ouverture (43) destinée à assurer l'accès à un environnement très dangereux et hors de celui-ci, ainsi qu'au moins une paroi (40) de cloisonnement souple divisant l'enceinte en deux chambres ou plus, une ouverture étant ménagée dans ladite paroi, assurant l'accès entre les chambres internes. Deux volets de fermeture (41a) et (41b) chevauchent l'ouverture se trouvant dans la paroi (40) de cloisonnement, un étant situé du côté amont de la paroi de cloisonnement, l'autre étant situé du côté aval par rapport à la direction voulue du courant d'air de passage à travers l'enceinte, dans une direction allant de l'extrémité propre de l'enceinte jusqu'à l'extrémité sale.
