Abstract
A survey was made of the Cosan Chemical Corporation, Carlstadt, New Jersey, to determine the effectiveness of the measures used to control worker exposure to mercury (7439976). This firm manufactured fungicides and bactericides used as additives for the paint and coatings industry, and catalysts for the plastics industry. Of the 50 employees, 14 work in the phenyl-mercuric- acetate (PMA) building. A Calgon Vent-sorb filter was used to remove mercury vapor from the discharge of the vacuum pump in the elemental mercury transfer system. Mercuric-oxide (21908532) was added to a reactor through an opening with a specially designed removable exhaust hood. Teflon gaskets were used at flange connections. Single or double mechanical pump seals were used. Powdered PMA was packaged in plastic lined drums underneath the rotary valve and delivery chute on the baghouse. A venturi scrubber was used to remove acetic-acid (64197) from the baghouse exhaust air stream. The operation of the room exhaust fans, drum loading exhaust hood, and filter press exhaust hood was described. Personal protective equipment was listed and work practices were delineated. Biological monitoring at the site included both blood and urine analyses. Air contamination monitoring was an ongoing program. Preemployment and annual physical examinations were provided for production workers. Levels of mercury vapor at this facility were kept below the recommended level of 0.1mg/m3.
