Environmental samples were collected and one employee completed a nondirected medical questionnaire on May 23, 1979 at the second floor of the Town Center Associates Building (SIC-6022) in Rockville, Maryland. The evaluation was prompted by a request from an authorized representative of approximately 35 employees to investigate a complaint of irritations from exposure to what was described as gray fuzz from the heating and cooling vents. Air samples were analyzed for total and respirable particulates, and fibrous-glass (14808607) content. Concentrations of total dust (0.05 milligrams per cubic meter of air (mg/cu M)), respirable dust (0.03 mg/cu m), and fibrous glass (not detectable) were all below OSHA limits (15 mg/cu m, 5 mg/cu m, and 0.01 fibers per cubic centimeter of air, respectively). It is concluded that there was no health hazard present and that the worker who completed the questionnaire had experienced an individual sensitivity to the gray fuzz. Observations are presented concerning potential worker discomfort due to fibrous-glass exposure.
