ABSTRACT:
An improved 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 work space within which an amalgamator unit, work platform, 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 amalgamator or work platform. Filtered air inlets are provided at each side of the work enclosure and a filtered air outlet is installed in the rear wall thereof above the work area. A fan unit is mounted exteriorly of the enclosure proximate the air outlet to maintain subatmospheric pressure within the enclosure and to cause air to be continuously drawn inwardly through the air inlets, through the work area and upwardly and rearwardly toward the filtered outlet. Use of the enclosure permits hazardous materials to be safely and expeditiously handled and stored without fear of environmental contamination.
