Определение характеристик наиболее травмоопасных профессий работников промышленных энергетических объектов с точки зрения летального исхода

Abstract

Electric power facilities traditionally demonstrate high rates of the fatal injuries. At the same time, the share of technical causes of injuries decreases annually. To reduce occupational injuries, the most promising measures are aimed at decreasing the influence of organizational and psychophysiological causes. Each of the potential causes of an injury can be described by the indicators that are uniquely associated with the work-related injuries and characterize the injured employee. The purpose of the study is to determine the characteristics of the employees in the most traumatic professions in the electric power industry who suffered as the result of injuries with fatality. Methodological approach is proposed related to the determination of the characteristic parameters of employees of the operating and maintenance personnel in the electric power industry. It consists of several stages. The first is the formation of the most common parameters, assignment to the group with an increased risk of industrial injuries. The second is the definition of a list of the most traumatic professions in the electric power industry. The third is the introduction of a procedure for multivariate cluster analysis of the input statistical data. The fourth is the calculation of the parameters of employees of the most traumatic professions in the electric power industry with distribution by cluster groups. Cluster groups are formed for professions: electrician, electrical fitter, foreman and wireman, which account for 80 % of the fatal injuries in the electric power industry. The relevant characteristics of the employees are determined: age, length of service, period after testing knowledge on the occupational safety, class of the working conditions. The proposed methodological approach can be used for any industry where the employee is exposed to the harmful and hazardous production factors. The methodology allows to develop and carry out measures for reducing the level of injuries.
