In response to a request from Department of Transportation personnel, a health hazard evaluation was performed of the working environment at the Nassif Building (SIC-9621), Washington, DC. Employees were concerned about exposures to extremely low frequency (ELF) electric and magnetic fields. Magnetic fields in an area on the sixth floor had been found to be higher than on adjacent floors. Electric and magnetic fields were measured on the fifth, sixth, and seventh floors during a typical workday. Measured levels during the NIOSH investigation ranged from 1.6 to 1.9 volts per meter for the electric field and 0.2 to 1,271 milligauss for the magnetic field. These levels were below the limits in place at this time. There were slightly higher readings for magnetic fields in the southeast quadrant of the sixth floor; this was attributed to several sources including transformers, handholes, and laser printers. The authors conclude that no hazard existed at the time of the survey from exposure to ELF electric and magnetic fields. The authors recommend measures which may reduce the potential occupational exposure to electromagnetic fields.
