Children spend almost half of daylight hours in schools, so for parents the conditions in which a child learns are of great importance. Sanitary and hygienic indicators and lighting for children's health and immunity play a big role. Features of the child's body are such that even the slightest change in the microclimate is reflected in thermoregulation. That is why schoolchildren need to ensure the appropriate temperature and comfort. If the temperature regime in the school is not met, then the heat output of the growing organism increases, which leads to cooling, and in such a situation and to catarrhal diseases it is within reach.
Sanitary norms
The microclimate in any room depends on the air temperature, its humidity (relative), and the speed of movement. If the last two indicators are easy to adjust, then the temperature of the indoor air in schools depends on a number of factors. The most significant factor is the heat transfer of the heating system. If the school is connected to a central heating system, then all that the management of an educational institution can do is to install radiators with high efficiency. To maintain the air temperature in the school, high-quality double-glazed windows and tightly fitting doors are also helpful. If these measures do not help, it is recommended to keep a temperature log at school. The results of daily measurements can be presented to the heat supply organization.
According to the current standards, school attendance is possible at the following temperature regime:
- from 17 degrees in classrooms;
- from 15 degrees in school shops, workshops;
- from 15 degrees in the gym;
- from 19 degrees in the locker rooms and dressing rooms;
- from 16 degrees in the library;
- from 17 degrees in the assembly halls;
- from 17 degrees in toilets;
- from 21 degrees in the medicine room.
If the minimum temperature in the premises of the school is below normal, the abolition of classes is the only possible solution.
Weather
The temperature inside the school premises can not but depend on the temperature outside the window. Even the best quality windows and doors will not be saved from the cold, if the winter tires in the street. Severe frosts are often a reason for the official cancellation of employment. Appropriate standards have been developed in the CIS countries. So, the temperature at which schools are canceled is from -25 to -40 degrees. In addition, the value of wind speed. If it is less than two meters per second, then the training sessions are canceled at the following temperature regime:
- -30 degrees for students of grades 1-4;
- -35 degrees for students grades 1-9;
- -40 degrees for students of grades 1-11.
At a higher wind speed, the conditions for cancellation are as follows:
- -25 degrees for students of grades 1-4;
- -30 degrees for students of grades 1-9;
- -35 degrees for students grades 1-11.
At extreme air temperatures, unusual for specific regions, local TV channels, radio and print media inform the public about the closure of schools. But the best way to learn about whether classes are canceled at school is a phone call to the class teacher.
In the end, parents should be guided by common sense. If the street is a bitter frost, and going to school turns into an extreme test, then you should skip classes even if they are not officially canceled. It is easier to teach a child with the training material in his absence than to treat him from hypothermia and make out a sick list in the clinic so as not to get a reprimand from the management at work.
