Parametrization of the educational environmental factors in organizations of secondary vocational education

Objective: hygienic parameterization and integral analysis of the priority factors of the educational and industrial environment in vocational training organizations. Material and methods. The actual values of the educational and working environment factors were determined in accordance with the requirements of Russian Federation sanitary regulations 2.4.3648–20 and hygienic rules and sanitary norms 1.2.3685–21. Parameterization of the educational and working environment factors was carried out using factor analysis method, integral analysis of priority factors according to N.I. Novichkova’s methodology. Results. The contribution of the leading production factors to the total variance of the indicators of the educational and industrial environment of the vocational school amounted to 23.8, 19.4 and 18.9%. The total accumulated contribution of the factors to the total variance was 65%. The first component included indicators of chemical air pollution in the work area, the second and third factors were sound pressure and vibration levels in the workplace, respectively. The integral score of the three factors was: 2.4–2.02, 1.18–1.46 and 1.17–1.2 points, respectively. Noise and vibration were categorized as conditionally significant factors, and the “chemical” factor had an “unsatisfactory” degree of compliance with modern hygienic requirements. Conclusion. Comprehensive studies of learning conditions in vocational training organizations allowed us to determine the structure of educational and production factors. The roles of chemical and physical factors in the framework of the indication of the leading unfavorable production parameters of the educational environment are established.
