In the conditions of operation of operators of thermal power plants, there are factors that, according to MM Khananashvili [7], in their unfavorable combination can lead to information neurosis and other diseases [3]. These factors include: a large amount of information to be processed, a lack of time to make a decision, a high level of motivation. The production need for a shift work schedule for operators to maintain a continuous production cycle is also an unfavorable factor and, according to the classification by the degree of intensity of shift work [4], corresponds to category III, which defines such work as stressful.

Numerous studies on the hygiene and physiology of labor of power plant operators, most fully summarized recently [1-4], indicate the relevance of further study of the state of the body in TPP operators, since these persons are characterized by an early deterioration in health (increased blood pressure, central nervous system, diseases of the digestive system, etc.), to a certain extent contributing to the forced transition of highly qualified operators to another job.

Determination of the presence of a connection between the state of the body of operators and the efficiency of their work shows that the change in physiological functions to ensure it occurs unevenly throughout the body. Maintaining work results at an optimal technological level contributes to an increase in the level of activation of the body. Ensuring the optimal technological process over a long period of change occurs due to the tension of the physiological functions of the body, as a result of which their deterioration occurs.

Therefore, in order to ensure long-term working capacity, effective for production and optimal for the organism of TPP operators, it is advisable to carry out preventive measures aimed at improving working and rest conditions.

Pointing to the importance of organizational measures for the preservation of human health in the conditions of scientific and technological revolution, II. K. Anokhin wrote that no crazy rhythm of our time, no acuteness of nervous experiences can cause hypertension, if it is a rhythm, if periods of greatest stress alternate with periods of rest. To prevent the deterioration of the efficiency of the technological process by the operators of TPPs, especially on the evening shift, it is necessary to notify the operators by phone, the selector about the most likely occurrence of errors in the regulation of the process or missing signals from the unit in the last three hours of operation; use the usual preventive measures (short physical training pauses, listening to music); implement other organizational measures.
