RISK MANAGEMENT BASED ON THE PERFORMANCE INDICATORS OF OCCUPATIONAL HEALTH AND SAFETY MEASURES AND THE SAFETY RAINBOW CLASSIFICATION

Abstract

The article proposes the use of coefficients of efficiency and effectiveness of measures, the degree of effectiveness of measures to manage the probability of negative events and risks in general. The introduction of the first universal classifier of measures "Safety Rainbow". Design/methodology/approach. To determine the effectiveness coefficient of security measures, an expert evaluation method was used to assess the consistency of expert opinions by calculating the concordance coefficient, based on the data obtained, a formula (polynomial) of the effectiveness of measures was determined, a new calculation formula was used to determine the probability of events, the effectiveness coefficient of security measures was determined as the share of the effectiveness coefficient in the cost of the measure per year, the degree of effectiveness is the total effectiveness of all measures used, given by The effectiveness coefficient of measures can be used both to determine the level of probability of negative events, as demonstrated by the matrix method of risk assessment, and in other occupational health and safety issues. The measure effectiveness ratio allows to prioritise measures for the purpose of rational use of resources. The degree of effectiveness of measures should be used to understand the prospects for reducing the level of risk and effective hazard management. The principles of ranking measures are laid down in the universal classifier "Safety Rainbow" and allow covering all possible measures for various hazards, works and not only in the field of occupational safety and health. Research limitations/implications. The proposed methodology is universal and can be used not only in the application of the matrix method of risk assessment, but also in other methods and not only in the field of occupational safety and health. The developed methodology of risk assessment allows to perform once an expert assessment of the effectiveness of safety measures and in the future by personnel who do not have sufficient qualifications in the relevant field of activity to perform promptly and efficiently assess and manage risks, develop additional safety measures, rationally use resources, including the use of computer programs, mobile applications, etc. Originality and significance. The proposed methods are used for the first time.
