Analysis of the current regulatory framework of the Russian Federation in the field of occupational risk assessment, as well as current methods and guidelines with recommendatory nature, showed that at present there is no adequate methods that allows to fully assess possible risks in the workplace.
The article deals with the issues of assessing the risk of damage to the employee health in the electric power industry based on the information that most fully describes the potentially possible risk of injury to health. Mathematical tool was proposed and substantiated for calculating the risk of damage to health based on the complex approach to the analysis of such basic data as an information about working conditions, safety of personal protective equipment, results of periodic medical examinations, individual parameters of the employee (age and work experience), results of work injuries investigation.
In order to take into account possible consequences for an employee as a result of exposure factors not identified in the framework of the special assessment of working conditions, the occupational rate was developed, and also an occupational injury rate was introduced, which is required for recording work injuries that occurred in the last 5 years.
As a result of the analysis of the existing classifications of risk levels it is established that the most appropriate is the risk assessment using the four-level scale that simultaneously meets the requirements of the regulatory-legal documents of the Russian Federation, and the recommendations of the Russian and international standards in the field of risk assessment.
To assess the complex effect on the magnitude of risk of causing harm to the health of the employee in the power sector, the algorithm was proposed, based on which the risk values were calculated for the employees of the branch of the electric grid company and classified by risk groups.
