Effect of Organizational, Psychosocial and Ecological Labor Conditions Factors on Fatigue and Health of Shipbuilding Workers

Abstract

The development of Fatigue Risk Management System (FRMS) in various industries and transport is an indicator of the relevance of the issue of professionally caused fatigue, the importance of which for the safety and health of shipbuilding workers has been poorly studied. The aim of the study was to characterize the effect of organizational, psychosocial, environmental and non-occupational factors affecting fatigue and health indicators of shipyard workers. There is an prevalence of the risk of severe fatigue among 8,8 ± 2,8 % of workers, 15,4 ± 7,2 % of foremen, 7,7 ± 7,7 % of engineers. The main fatigue causes are indicators of the labor regime and the working environment in workers and increased labor intensity, negative characteristics of functional duties and psychosocial climate, extra-curricular load in foremen. The risk of reducing the efficiency of workers, foremen and engineers due to their being at the workplace in a state of severe fatigue is 8–12 % of working time. The total deficit of rest formed during working hours and free time is the main source of risks of acute and chronic fatigue. The data obtained are the justification for the relevance of the introduction of FRMS to improve the efficiency, safety and reliability of labor processes in shipbuilding enterprises.
