Sanitary and hygienic characteristics of the environment in the educational spaces of a sports university

Abstract

Aim assessment of sanitary and hygienic conditions in the classrooms of a sports university. Material and methods. The following parameters were measured and analyzed: temperature, relative humidity, air velocity in 12 classrooms, 6 lecture halls and 3 sports halls. The national standards GOST 30494-2011 and Sanitary Rules and Regulations 2.1.2.3304-15 were applied for the assessment of the environmental parameters during an academic day in the cold and warm seasons. Results. In the cold season, the temperature within the standard limits was registered only in 6.89 0.84% of classrooms, in 18.10 1.53% of lecture halls and in 9.17 1.32% of the sports halls. In warm season, the excess of air temperature above acceptable values was more often observed in sports halls (81.25 1.78% of samples). The increase in the average air temperature by the end of the school day in the cold period was 11.67 0.44% in classrooms and 10.69 0.54% in lecture halls, in the warm season the increase was 7.5 0.88% and 11.11 0.5%, respectively. The values of relative humidity in the warm period of the year were 43.89 2.33% for classrooms, 44.33 2.39% for lecture halls, and 43.98 2.61% for sports halls. In the cold season, the relative air humidity was significantly lower than optimal values: on average, in the classrooms it did not exceed 12.98 1.91%, in lecture rooms 14.94 2.39%, in sports halls 17.29 4.22%. Conclusion. The study results dictate the need to strengthen continuous monitoring of microclimate parameters of educational spaces in a sports university, regular ventilation, adjustment of air conditioning systems for "heating" or "cooling" mode and their timely maintenance.
