Abstract
Worker exposure to chemicals in the polychlorinated-biphenyls (1336363) (PCB) production area at the Sauget, Illinois facility of the Monsanto Industrial Chemicals Company (SIC-2869) was investigated on July 21 and 22, 1976. The facility was included in an industry wide NIOSH study of industries using PCBs. Air samples were collected for evaluation of PCB, iron-chloride (12040572), silica (7631869), and chlorine (7782505) exposure. About 25 employees were involved in the production of PCBs. The facility contained a dispensary with nurses on duty for all shifts; industrial hygiene matters were handled by an environmental control group. Safety meetings were held monthly by the safety department. The PCBs under production during the survey were for Aroclor-1016 (12674112) (42 percent chlorine). PCB personal air samples ranged from 16 to 55 micrograms per cubic meter (CuM). These are well below the federal standard for chlorodiphenyl (42 percent of chlorine) of 1 milligram (mg) /CuM. One sample had an iron concentration of 8.1 mg/CuM. Since the procedure of adding iron- chloride only takes an average of 3 minutes per shift, the workers time weighted average was well below the recommended American Conference of Governmental Industrial Hygienists threshold limit value for iron salts of 1mg/CuM based upon soluble iron. No concentrations of chlorine were detected. The author recommends the use of an approved respirator when handling iron-chloride and an approved dust respirator when handling free silica, and engineering methods to prevent employee exposure to PCBs. Emergency equipment should be readily available in case of a chlorine leak.
