Current Problems of Normalization of Physical Factors in the Operation of Computer Equipment

Abstract

Analysis of national and international databases on the safety of physical factors. Non-regulatory working conditions of computer users are largely due to the lack of national sanitary norms and rules for the safe operation of computer equipment. Current international standards relate to the radiative properties of technical means and do not consider the conditions in the workplace. It is shown that general standards on maximum permissible levels of physical factors are unacceptable for their application in the field of user safety due to high maximum permissible levels of electromagnetic fields, infrasound, electrostatic fields, etc. In addition, there are significant differences in the various current regulations regarding limit levels and methods for determining the integrated electromagnetic load. When developing sanitary norms for the safety of users of computer equipment, the dependence of air quality on the aeroionic composition on the presence of surface electrophysical charges on polymer surfaces and models of technical means and means of air cooling should be taken into account. It is advisable to regulate the use of artificial air ionization devices. Given the relatively low levels of electromagnetic fields in the workplace of users, it is necessary to regulate the ways of controlling the levels of electromagnetic fields with acceptable errors. Given the impact of unstable operation of technical ways on the psychomatic state of users in the process of developing the relevant standard, it is necessary to take into account the stable operation of equipment by increasing the levels of electromagnetic compatibility of equipment.
