Mercury control technology assessment study, Troy Chemical Corporation, Newark, New Jersey, preliminary survey report for the site visit of October 15, 1981.

An on site visit was made to the Troy Chemical Corporation, Newark, New Jersey to evaluate control methods in place to reduce hazards to workers involved with mercury (7439976). Products included antiskin agents, bactericides, bodying agents, defoamers, dryers, mildewcides, preservatives, and wetting agents. Process descriptions were offered for raw mercury handling, mercuric/mercurous chloride production, mercuric-oxide production, organomercurial production, and mercury reclamation. Control methods described included mercury vapor control through the use of mercury vapor adsorbers, exhaust hoods, and condenser/adsorber systems. For the control of mercury particulates the oxide grinding and packaging system, PMA grinding exhaust system, and spill protection pallets were used. Cyclones and filter bags were installed for reducing mercury particulate concentrations in the areas of potential exposure. Personal protective equipment, work practices, biological monitoring, and air contaminant monitoring programs were described. The use of a sauna for removing mercury from the workers was a new approach that may reduce mercury levels in the body. It is suggested that the company investigate the ventilation of oven doors on the retorts in the mercury reclamation facility. An in depth survey is not recommended as adequate information on mercury control was obtained during the preliminary site visit.
