An analytical data mining approach to the assessment of an occupational risks is proposed and based on the use of an injury safety indicator, which allows to determine the degree of safety (hazard) of the workplace, to carry out statistical processing of the results collected with its help, which will help with further planning of labour protection measures. The results of an occupational risk assessment with the use of an injury safety indicator make it possible to predict the levels of occupational risks at various workplaces, which makes it possible to develop the optimal management decisions for the preservation of the life and health of workers in enterprises. The prospect of using data mining methods in the tasks of labour protection management at an enterprise opens up the possibility of creating decision-making mechanisms that take into account the dynamic state of the working environment and make it possible to increase the validity of the choice of priority labour protection measures.
