In response to a request from employees of the New York Telephone Company (SIC-3661) Central Office facility in White Plains, New York, a study was conducted on possible exposures to electromagnetic fields (EMFs) and chemicals as well as indoor air quality in response to a concern about a perceived high incidence of cancer among employees working on the third floor of the building. Air and dust samples were collected and analyzed for trace metal content, temperature, relative humidity, and carbon-dioxide levels; the presence of EMFs and ionizing radiation was evaluated as well. In addition employees were given medical evaluations. All EMF measurements were within the American Conference of Governmental Industrial Hygienists occupational exposure standards. Adequate ventilation and very low levels of chemical exposures were seen. Humidity exceeded recommended levels in several areas. Radioactive vacuum tubes had previously been in widespread use at this facility. The authors conclude that exposures to trace levels of chemical contaminants should not be in excess of occupational standards. Electrical shock potential existed. Electric and magnetic fields did not exceed occupational standards. The role of ionizing radiation from vacuum tubes previously in use must be considered in any study of cancer among telephone company central office employees.
