ABSTRACT:
A controlled atmosphere work enclosure for use in handling hazardous materials such as mercury and mercury alloys. The work enclosure comprises a hollow housing defining a workspace having disposed intermediate thereof a perforated work platform upon which an amalgamator unit or the like can be mounted. Replaceable flexible plastic or rubber gloves are sealably affixed to glove rings mounted on the front of the unit to permit convenient working access to the platform. Filtered air inlets are provided above the work platform and a filtered air outlet is installed below the platform. Fan units are provided proximate the floor to maintain subatmospheric pressure within the enclosure and to cause air to be continuously drawn inwardly through the air inlets, rapidly downward past and through the work platform and outwardly through the filtered outlet. Use of the enclosure permits hazardous materials to be safely and expeditiously handled and stored without fear of environmental contamination.
