The main safety measures when working with video display terminals are reflected in the Sanitary and Epidemiological Rules and Standards SanPiN 2.2.2/2.4.1340-03. Sanitary rules and regulations are intended to prevent adverse effects on humans from harmful factors that accompany work with video display terminals (VDT) and personal electronic computers (PCs). All VDTs must have a certificate of state registration. If the technical documentation for the RCCB does not contain data on the optimal and permissible ranges of values ​​of ergonomic parameters, the operation of the RCCB is not allowed.

VDT and PC premises must have natural and artificial lighting. Natural lighting should be provided through light openings.

The location of workplaces with VDTs and PCs for adult users in basements is not permitted. In cases of production necessity, it can be carried out only in agreement with the bodies and institutions of the State Sanitary and Epidemiological Supervision.

The area per workstation of PC users with a VDT based on a cathode ray tube (CRT) must be at least 6 m2 and with a VDT based on flat discrete screens (liquid crystal, plasma) - 4.5 m2.

Polymer materials used for interior decoration of premises with VDTs and PCs must be approved for use by bodies and institutions of State and Sanitary-Epidemiological Supervision.

In industrial premises in which work on VDTs and PCs is the main activity (control rooms, operator rooms, computer rooms, etc.) should be provided with optimal microclimate parameters.

Production premises in which mainly VDTs and PCs are used for work (control rooms, operator rooms, etc.) should not border on premises in which noise and vibration levels exceed standardized values ​​(mechanical shops, workshops, etc.).

Premises with VDTs and PCs must be equipped with heating, air conditioning systems or effective supply and exhaust ventilation. Standard parameters of the microclimate, ionic composition of the air, and the content of harmful substances in it must meet the requirements of the Sanitary Rules.

In production premises operated by VDTs and PCs, noise and vibration levels at workplaces should not exceed the values ​​established for these types of work by the “Sanitary Standards for Permissible Noise Levels at Workplaces” and “Sanitary Standards for Vibration of Workplaces”.

Artificial lighting in the operating rooms of VDTs and PCs should be provided by a system of general uniform lighting. In production and administrative and public premises, in cases where work is primarily done with documents, it is allowed to use a combined lighting system (in addition to general lighting, local lighting lamps are additionally installed to illuminate the area where documents are located).

The illumination on the table surface in the area where the working document is placed should be 300-500 Lux.

As light sources for artificial lighting, predominantly LB type fluorescent lamps should be used. It is allowed to use incandescent lamps in local lighting fixtures that have a non-translucent reflector with a protective angle of at least 40°.

5.2.5 Requirements for organizing the work and rest regime when working with high-speed electronic devices and personal computers

The requirements for organizing the work and rest regime when working with VDTs and PCs are established by sanitary rules and norms - Sanitary rules and norms SanPiN 2.2.2.542-96 “Hygienic requirements for video display terminals, personal electronic computers and work organization” (approved by resolution of the State Committee for Sanitary and Epidemiological Supervision RF dated July 14, 1996 N 14).

According to SanPiN 2.2.2.542-96:

Work and rest regimes when working with PCs and VDTs should be organized depending on the type and category of work activity.

Types of work activities are divided into 3 groups: group A - work on reading information from the screen of a VDT or PC with a preliminary request; group B - work on entering information; group B - creative work in dialogue mode with a computer. When performing work related to different types of work activity during a work shift, the main work with a PC and VDT should be taken as that which takes up at least 50% of the time during a work shift or working day.

For types of work activities, 3 categories of severity and intensity of work with VDTs and PCs are established, which are determined by:

for group A - according to the total number of characters read per work shift, but not more than 60,000 characters per shift;

for group B - according to the total number of characters read or entered per work shift, but not more than 40,000 characters per shift;

for group B - based on the total time of direct work with VDTs and PCs per work shift, but not more than 6 hours per shift.

The duration of the lunch break is determined by the current labor legislation and the internal labor regulations of the enterprise (organization, institution).

To ensure optimal performance and health of professional users, regulated breaks must be established throughout the work shift.

The time of regulated breaks during a work shift should be set depending on its duration, type and category of work activity.

The duration of continuous work with VDT without a regulated break should not exceed 2 hours.

When working with VDTs and PCs on the night shift (from 10 p.m. to 6 a.m.), regardless of the category and type of work activity, the duration of regulated breaks should increase by 60 minutes.

With an 8-hour work shift and work on VDT ​​and PC, regulated breaks should be established:

With a 12-hour work shift, regulated breaks should be established in the first 8 hours of work, similar to breaks during an 8-hour work shift, and during the last 4 hours of work, regardless of the category and type of work, every hour lasting 15 minutes.

During regulated breaks, in order to reduce neuro-emotional stress, fatigue of the visual analyzer, eliminate the influence of physical inactivity and hypokinesia, and prevent the development of postural fatigue, it is advisable to perform the sets of exercises set out in (Appendix 16, Appendix 17 and Appendix 18 to SanPiN 2.2.2.542-96) .

In order to reduce the negative impact of monotony, it is advisable to use alternating operations of meaningful text and numerical data (changing the content of work), alternating editing texts and entering data (changing the content of work).

In cases where visual discomfort and other unfavorable subjective sensations occur in those working with VDTs and PCs, despite compliance with sanitary, hygienic, ergonomic requirements, work and rest schedules, an individual approach should be used to limit the time spent working with VDTs and PCs and correct the duration of rest breaks or change activities to another that is not related to the use of VDTs and PCs.

Those working on VDTs and PCs with a high level of tension during regulated breaks and at the end of the working day are given psychological relief in specially equipped rooms (psychological relief room).
