EVALUATION OF JOINT EFFECT OF FACTORS OF SMALL INTENSITY OF PRODUCTION ENVIRONMENT AND LABOR PROCESS ON WORK ABILITY AND ERROR OF ACTION OF OPERATORS OF HIGH-TECH ENERGY COMPLEXES
Increase in complexity and speed of production processes puts forward strong requirements for accuracy of operators' actions, quick decision-making in performance of management functions. Statistical analysis of data on the oil refining industry showed that a refinery with a capacity of 10 million tons of oil per year loses in average $ 4 million only from accidents caused by operator's errors. Around 40 % of accidents and incidents occur due to operator's errors. Reasons for such errors are related to personal qualities, lack of education, training, as well as to factors of low intensity of production environment. A complex of factors of low intensity can lead to hidden up to a certain time “compensated” homeostatic disturbances or modify harmful effect with demonstration of inadequate reactions. The article presents results of study of operators of central control room of two technological departments of high-tech and hazard production (oil and gas) complex to assess combined influence of factors of low intensity of production environment and labor process on work ability and error of actions during labor process. Studies have showed that a long intense functional load on body's systems with influence of factors of low intensity of production environment and labor process lead to development of fatigue and increased tension that operators suffer during day and night shifts. Significant tension of sensory and intellectual systems of the organism with fatigue determines high physiological cost of labor of high-tech production operators. That indicates a need to develop preventive innovative methods to correct a physiological state of operators to improve their performance and take errors off labor, which reduce risk of physical illness.
