Centralized repair bureaus (CBR) have been created and operated on the city telephone network (GTS). Increasing the efficiency of their work was considered from the point of view of solving organizational and technical issues | 2-4]. The hygienic aspect of the work of CBR workers has not been studied. Meanwhile, the Central Banks have been created in all major cities of the country, they are serviced by workers of 2 main professions - operators and dispatchers. The CBR operates modern equipment, including displays. The foregoing has led to research for the hygienic assessment of working conditions in the Central Bank of Russia and the development of a set of health-improving measures.

The studies were carried out in 9 Central Banks of Moscow, Leningrad, Kiev, Minsk, Donetsk. 78 workplaces of operators and dispatchers were examined on the basis of a generally accepted methodological approach and a set of methods that ensure the achievement of the set goal.

The work of operators and dispatchers is largely of the same type and is organized at the test-measuring table (IMS) or display. For operators, it consists in accepting an order from a subscriber for repairs, testing and measuring the damaged communication line, placing an order for repairs and transferring it to a dispatcher. The dispatcher further checks the communication line, clarifies the cause of the malfunction, communicates with the electrician on the line and by instruments, monitoring his actions, and finally checks the operability of the restored communication line.

Observations of the work of operators and dispatchers at the time of dialogue with a subscriber or an electrician on the line showed that in some cases, intense noise occurs due to excessively loud negotiation. However, it is difficult for employees to objectively assess and control the volume of a conversation with a subscriber.

To objectify the control of the loudness (intensity) of industrial noise, it is recommended to install threshold devices at workplaces with the inclusion of light indication of exceeding the permissible noise level in the form of an acoustic switch.

Thus, the change in the internal layout of the CBR premises, the rational formation of green zones, the use of an air conditioning system and the introduction of acoustic control means optimize the working conditions of operators and dispatchers. At present, these and a number of other measures are drawn up in the form of "Methodological recommendations for optimizing the working conditions of employees of the centralized bureau for repairing the city telephone network" (M., 1988). Practical recommendations for the rationalization of labor when working with displays can be borrowed from a number of publications [1, 5, 7].
