Environmental air samples were analyzed for total and respirable dust, formaldehyde (50000), carbon-monoxide (630080), anisidine (29191524), o-toluidine (95534), and dimethylformamide (68122) at the Rock Hill Printing and Finishing Company (SIC-2260), Rock Hill, North Carolina on August 4, 1980. Medical interviews were also conducted with 22 workers. A representative of the Amalgamated Clothing and Textile Workers Union requested the evaluation on behalf of approximately 1700 workers. Exposures to formaldehyde were below the OSHA standard of 3 parts per million (ppm) for a time weighted average (TWA). Total dust concentrations were all less than 1 milligram per cubic meter (mg/cu m) compared with the OSHA TWA standard of 15mg/cu m. Respirable dust concentrations were all below 0.5mg/cu m. Carbon-monoxide was detected in concentrations ranging up to 3.5ppm well below the OSHA standard of 50ppm. Anisidine, o-toluidine, and dimethylformamide were not detected. Medical interviews revealed complaints of eye and upper respiratory tract irritation among workers handling solvents and those working in the roller print and aging areas. The authors recommend that worker exposures to formaldehyde be reduced to the lowest feasible limit due to the potential carcinogenicity of the chemical. They also recommend improved industrial hygiene monitoring, worker education, better ventilation in areas of solvent exposure, and an industrial hygiene survey of coating operations workers to develop an adequate medical surveillance program.
