Technical Assistance Report No.TA-80-115-802, Centers For Disease Control, Atlanta, Georgia.

Employee exposures to xylene (1330207), ethyl-alcohol (64175), formaldehyde (50000) and asbestos (1332214) were evaluated at the Centers for Disease Control (CDC) (SIC-9199) in Atlanta, Georgia on October 9 and 10, 1980. The measurements were made in response to a request from the Office of Biosafety at CDC to evaluate employee exposure to organic solvents and asbestos. Personal and area samples for evaluating exposure to organic solvents were analyzed by gas chromatography; asbestos was estimated by polarized light microscopy and dispersion staining techniques. In five area and personal samples, xylene concentrations ranged from 1 to 5 milligrams per cubic meter (mg/cu m); the OSHA permissible exposure limit (PEL) is 435mg/cu m on a 8 hour time weighted average. Ethyl- alcohol ranged from 6 to 8mg/cu m; the OSHA PEL for ethyl alcohol is 1900mg/cu m. Formaldehyde ranged from 1 to 3mg/cu m, exceeding the NIOSH ceiling limit of 1.2mg/cu m for a 30 minute average. No asbestos fibers were found in air samples, but 6 of 13 bulk insulation samples contained chrysotile asbestos in concentrations 5 to 60 percent. The author concludes that a health hazard exists at CDC from overexposure to formaldehyde, and six areas have a potential for airborne asbestos exposure. Recommendations include the provision of adequate ventilation to control formaldehyde vapors, the replacement of asbestos insulation, provision of an employee education program, and provision of personal protective equipment.
