In response to a request from an employee at National Cover of Atlanta, Inc. (SIC-2782), Lawrenceville, Georgia, an evaluation was made of possible hazardous working conditions. High quality three ring binders and other packaging materials were produced by this company. Plastic covers were sealed by radiofrequency heat sealers around a cardboard insert. The possibility of an increased number of spontaneous abortions among women employees was investigated through the use of a questionnaire administered to current and former female workers. There were 225 pregnancies in the 148 women in the study; 158 occurred among women not working outside the home, 52 occurred to women employed outside the home but not at National Cover, and 15 occurred among women employed at National Cover. The adverse outcome rate was 53 percent for pregnant women employed at National Cover, 13 percent for women not working and 10 percent for women working elsewhere. All measurements of electrical and magnetic fields near the heat sealing machines were below the OSHA standards. Exposure to solvent vapors was up to 80 percent of the threshold limit value for solvent mixtures. The authors recommend product substitution to less toxic organic solvents and inks, and the installation of an industrial ventilation system. The manufacturer of the radiofrequency heat sealing equipment should be contacted to provide a properly designed shield for these machines.
