hazardous work, productivity of information retrieval, professional selection, psychophysiological functions, high risk activities, attention


The purpose of the study was to improve methodological approaches to determination of attention as a criterion of professional fitness of persons working in hazardous conditions. To determine attention, we evaluated productivity index of information retrieval by “Numeric Square” method. When analyzing the data obtained during the study of attention (including its switching) on ​​the productivity of information retrieval in persons who perform different types of hazardous work and the difference between the type of work performed. The vast majority of surveyed persons working in hazardous conditions were found to meet professional requirements (70%) by psychophysiological function “attention” (including its switching). The group of “conditionally fit” included (25%) subjects and “unfit” – 5%.
