In response to a request from a group of employees at the Pitney Bowes Management Services, Ropes and Gray Photocopy Center (SIC- 7334), Boston, Massachusetts, an evaluation was undertaken of worker exposures to photocopy emissions. The photocopy center has been in operation for 2 years. Six full time employees worked the day shift operating six photocopiers of various models. Approximately 1 million copies were generated monthly at the site. Qualitative and quantitative analyses of air samples taken for volatile organic carbons revealed trace amounts of 1,1,1-trichloroethane (71556), isooctane (540841), toluene (108883), xylene (1330207), and benzene (71432). Ozone (10028156) concentrations as high as 0.41 parts per million (ppm) were detected at approximately 3 feet from the exhaust of each photocopier. Carbon-dioxide (124389) concentrations ranged from 300 to 825ppm. Respirable dust concentrations ranged from less than 10 to 50 micrograms per cubic meter. Carbon-monoxide (630080) was not detected. The authors conclude that the evaluation did not reveal a hazard to explain the respiratory symptoms experienced by the workers. The finding that the ventilation system moved too small an amount of air in a measured period of time may account for the accumulation of airborne contaminants within the building. Recommendations were made to improve the ventilation.
