Occupational health and functional condition of the organ of vision in employees at the modern production of microelectronics

Abstract

Introduction. In the emerging digital economy, microelectronics is a driver of civilizational progress, ensuring technological sovereignty, and determines the level of development of modern society. Its elemental base is continuously developing and improving in the direction of microminiaturization of electronic components and complex miniaturization of equipment. In this regard, the purpose of the study was a hygienic assessment of operational conditions and the functional state of the visual analyzer in employees working in the modern production of microchips and semiconductor devices.Material and methods. At the workplaces of the radio components collectors there were measured sound levels, artificial lighting, and microclimate parameters; air pollution by chemicals; the hardness and intensity of work are estimated based on timing observations. The functional state of the organ of vision was studied once and in the dynamics of the working day. The operation of the accommodation apparatus, as well as the state of the receptor link on the thresholds of color perception, were studied.Results. Levels of chemical and physical factors of the operational environment during assembly, sealing, and labeling operations were revealed not to be over normalized values. According to the results of timing observations, the time of use of optical instruments is from 55 to 75% of the shift, which characterizes the work process as stressful as grade 3 (harmful) 1st and 2nd degree, according to the duration of being in a fixed sitting position for more than 50% of the time, the severity of labor is estimated as grade 3 1st degree. The obtained data indicate a decrease in the volume of accommodation of the eye and an increase in color discrimination thresholds in the dynamics of the working day.Discussion. In shaping the operational conditions of workers who assemble and control products, the decisive role belongs to the hardness and intensity of the labor process, in particular, to the long-term restriction of motor activity in a fixed sitting position and the visual load associated with performing precision work using optical instruments. A change in the function of vision, characterized by a violation of the accommodative ability of the eye, a decrease in color perception, indicates the development of visual fatigue in collectors.Conclusion. Despite the modernization of production equipment, a significant proportion of labor operations for the assembly of products are carried out manually. Given the impossibility of ensuring complete automation of technological processes at the enterprises, preventive measures should be aimed at organizing a rational mode of operation that provides relief of vision.
