The microclimate of industrial premises, which is determined by the temperature of the air, its composition and pressure, relative humidity, and the speed of flow, has a great influence on the well-being and performance of a person. In accordance with GOST 12.1.005-76 and SNiPom II-4-79, the following sanitary and hygienic requirements should be observed / 16 /.
Small deviations in the content of gases that make up the atmospheric air (nitrogen -78.08%, oxygen -20.95%, carbon dioxide-0.03%, argon and other gases -0.94%), and first of all, a decrease in oxygen concentration and an increase in carbon dioxide content, reduce efficiency, and with significant deviations from the norm, the atmosphere becomes dangerous to human life.
The well-being of a worker largely depends on the temperature of the ambient air (over 20C), a person quickly gets tired, his working capacity decreases, the body relaxes, and sweating increases.
In this regard, sanitary standards establish the permissible temperature of industrial premises (below 13C) of classes, offices, laboratories, educational institutions(16-20 C), gymnasiums, lobbies, corridors (14-16 C).
Humidity of the air also affects a person's well-being. According to sanitary standards, the permissible humidity in classrooms should be 40-60%; in the warm season, an increase of up to 75% is possible.
The movement of the surrounding air is important for a person's well-being. This parameter is also defined by sanitary standards. Average air velocities in educational institutions should be 0.2-0.5 m / s in the cold and transitional seasons and 0.5-1.5 m / s in the warm seasons.
Ventilation is used to maintain a normal air composition that meets hygienic requirements in the educational and production and auxiliary rooms, and to remove harmful gases, vapors and dust from them.
Ventilation is an adjustable air exchange in a room. Ventilation is also called a device that creates. In the absence of additional hazards, the air exchange rate is taken as 20 m3 / h per person.
The office and workshops, regardless of the presence of ventilation devices, must have opening transoms or other ventilation devices in the window openings, controlled from the floor. The opening area of the transoms or vents should be at least 1/50 of the floor area in order to ensure three times air exchange per hour.
Based on the experience of computer rooms, its area can be determined from the condition of 4.5-5 m2 per 1 student, the optimum temperature is 17-21 C, and the humidity is 40-60%. Due to the operation of machines, an increase in heat generation is characteristic of the offices, therefore it is necessary to provide for forced ventilation of the offices.
Good lighting of workplaces is one of the most important requirements for occupational safety.
With insufficient lighting, visual perception decreases, myopia develops, eye diseases and headaches appear. Due to constant eye strain, visual fatigue occurs.
Normal illumination is of great importance for educational institutions, where about 90% of all information received is perceived with the help of sight. Three types of lighting are commonly used: natural, artificial and mixed.
In educational institutions, desks and tables are placed so that the light falls on the left side of the students.
Emergency lighting fixtures are connected to the mains: independent from the working lighting network.
To enhance illumination with reflected wall light? Ceilings? The floors are painted in light colors: ceilings in White color, the upper parts of the walls - in gray, blue, lower brown, gray, blue, dark green; chalkboards- in brown or dark green, the covers of desks and tables - in green, light green, the bases of tables and chairs - in light colors.
One of the factors affecting occupational safety is the rational coloring of the premises and equipment. Correctly selected colors have a beneficial effect on the psyche of workers, reduce their visual and general fatigue.
When working with computers, it is important to observe favorable lighting conditions. The bright light makes it difficult to read the readings from the display, so on sunny days, cover the windows with light, light curtains. In order to avoid the reflection of surrounding objects on the screen, the display installed in the classroom should have some inclination (10-15 0) towards the student or side shields and a small visor. In the evening, at dusk, it is recommended to illuminate the classroom with an overhead light (150-300 lux).
