An investigation to determine the effects of various chemical exposures on workers was made at the Jefferson Chemical Co. (SIC- 2819) which produces a variety of chemical substances, many of which serve as feedstock to produce the final products. The majority of the substances are produced and handled in closed reactor systems and distillation units. The final products are loaded into tank cars, trucks and drums. General area and personal samples for organic vapors were obtained. Private interviews with employees selected at random were conducted and nondirected medical questionnaires were compiled. The first aid facilities and medical programs were also reviewed along with selected blood lead (7439921) data. A hazard to the health of laboratory workers did not exist at the time of the surveys as indicated by air sampling results. A potential health hazard existed for workers assigned to the refinery gas feedstock unit, due to benzene (71432) vapor exposures as indicated by air sampling results. A health hazard was not indicated for employees of the ethanolamine (141435) production unit based on the results of the type of air samples obtained. A health hazard was not indicated for employees of the phenol (108952) processing unit based on the results of the type air samples obtained. A determination of potential health hazards was not possible for the Cell Renewal Area due to the operation not being on line at the time of the surveys. A potential health hazard existed for employees of the DDM production unit based on work practice observations and spent catalyst dust analysis. The spent catalyst contained approximately 0.6 percent aniline (62533) and 9 percent diaminodiphenyl-methane (DDM) isomers by weight. The workers were not adequately protected for the catalyst dumping operation.
