Abstract:

Purpose. Development of calculation methods for analysis and evaluation of risk of technology-related accidents at hazardous production facilities.

Methodology. For the analysis and evaluation of the risk of accidents the stochastic method of safety analysis using the failure tree was used.

Findings. Different methodological approaches to risk assessment were considered. The research showed that the forecasting techniques currently used in Ukraine can determine only the boundary zone of the threshold of defeat. We suggest the technique that allows for quantitative risk assessment, in particular, individual, territorial and social risks. We recommend using the estimates obtained for the declaration of industrial safety of hazardous production facilities of industrial safety and the development of recommendations for risk reduction.

Originality. The article provides scientific rationale of the calculation methods for the analysis and evaluation of the risk of technology-related accidents at hazardous production facilities. It differs from the previous ones by taking into account the nature of the accident during the determination of individual risk, determining the time of workers’ stay in a hazardous area and their location. This allows us to analyze and evaluate the individual, territorial and social risks caused by the release of toxic substances more precisely.

Practical value. Results of the analysis and evaluation of the accidents risk are used for substantiation of technical measures providing industrial safety.
