The need for an efficient assessment of the occupational risk of the employees involved in the construction of buildings and structures was established. A study was conducted for substantiating the system for ensuring the safety of personnel in the construction complex using quantitative risk criteria developed based on of mathematical modeling. Technological processes at the construction sites and in the organizations are considered. The methods of complex (integral) system analysis, process analysis, aggregation and optimization of risk parameters were also applied.
Based on the systematic studies of the technological processes at facilities under construction, a methodology for assessing occupational risk was developed. The ways and means of achieving the strategic goal of the occupational safety, which is to ensure the safe professional activity of personnel, are considered. The possibility of forming a set of criteria for the quantitative assessment of occupational risk based on the mathematical modeling is shown. The key to obtaining efficient evaluative expressions is the use of real statistical data in the numerical form. The importance is noted considering the interaction of various harmful and hazardous production factors that affect personnel and are formed according to the principle of systems emergence. The developed criteria for the quantitative assessment of occupational risk are an objective and reliable basis for the development of an efficient system for ensuring the safety of construction employees.
The described technique is based on the fundamental provisions of the physical and mathematical theory, the scientific discipline «Life Safety», the theory of prognostic and experimental research. It can be used to develop measures for creating a safe working environment in all the industries.
