Abstract

The article considers the problem of forecasting and operational assessment of the distribution of the probability of occurrence of micro-injuries of workers. Experimental data were obtained as a result of approbation of the “System for improving labor safety for recording, analyzing and predicting micro-injuries ” based on software in construction organizations in the Belgorod region. Single-factor analysis of variance was used in the processing of experimental data to identify the most significant indicators that affect the likelihood of a microinjury to an employee. Models of the distribution of micro-injuries by gender, age, length of service and type of micro-injuries of workers are presented. The boundaries of "vulnerable" categories of workers are determined, for which it is necessary to develop effective measures to optimize the functioning of the occupational health and safety management system and injury prevention. A model for accounting and assessing micro injury has been developed based on the analysis of variance of the database registered through the software package of the digital platform implemented in construction organizations.
