Electromagnetic Safety of Workplaces Equipped with Computer Hardware

Methods and means of electromagnetic safety examination of automated workstations equipped with computer hardware are considered. National and international standards as well as the tools necessary for the examination are presented. The results of measuring the levels of electric field strength E, V/m, and magnetic flux density B, nT, at frequencies 5 Hz...2 kHz and 2...400 kHz in two office premises are discussed. It is established that there is an excess of safety standards for computer hardware in both rooms, as well as an increased level of general technogenic background frequencies of 5 Hz...2 kHz. Consideration of uncertainty of the measurement results by the method prescribed by the new normative documents confirms the made conclusions. The most probable reason for the established excess is the shortcomings in the installation of elements of the local area network connecting automated workstations. It is planned to continue the research involving students as part of the «Safe Computer» volunteer project.
