HHE determination report no. HHE-80-74-714, Standard Publishing Company, Cincinnati, Ohio.
Cincinnati, OH: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, HHE 80-74-714, 1980 Jul; :1-9
Environmental sampling was conducted, air circulation was observed, and bulk samples of a solvent were analyzed on March 4 and 12, and on April 3, 1980, at the Standard Publishing Company (SIC-2740), Cincinnati, Ohio, to evaluate complaints of eye and throat irritation from employees working in the platemaking process. These complaints initially developed after a new mercury vapor lamp was installed. The evaluation was requested by the management to determine the cause of the complaints from an unspecified number of workers. Bulk samples of Citation Developer and Citation Stencil Remover were analyzed by gas chromatographic and mass spectrographic procedures, and revealed perchloroethylene (127184) (PCE) as the major chemical constituent. The developer was a mixture of aliphatic-hydrocarbons. Ultraviolet tests were conducted. These tests demonstrated the presence of thermal degradation products of the stencil remover solvent, phosgene and hydrogen-chloride, were detected at concentrations of 0.15 and 1 part per million, (ppm) respectively. Air circulation observations indicated that an air current from the solvent area was carried into the stripper room where some of the symptomatic employees worked. The author concludes that the new mercury vapor lamp was responsible for PCE decomposition and fatty-acid particulate generation when solvent vapors came into contact with the lamp. He recommends substitution of the currently used solvent with a low toxic stencil remover that contains no chlorinated hydrocarbons, and the addition of a positive pressure ventilation system to prevent solvent vapors from entering the work room.
