An enclosure is provided for use in handling hazardous materials such as mercury. The enclosure includes a hollow housing having an opened bottom end. The walls of the housing are preferably fabricated from a clear plastic to provide unobstructed visibility. A bottom platform is provided for a work area and the opened bottom of the housing fits within the platform. A fan and filter unit is mounted in the top wall of the housing via an aperture to enable air to be drawn from the housing through the filter by the action of the fan. The air is filtered prior to discharge into the atmosphere to rid the same of mercury or obnoxious vapors. The internal hollow of the housing is accessed by means of a pair of ports located on a front wall of the housing. The ports are blocked by means of elastic bands which are flexed when a user's hands are inserted through the apertures to allow access to an amalgamator or other devices contained within the housing.
