The aims of the research is to analyze state of health of operators engaged in bottling of non-alcoholic and low-alcoholic drinks in "Obolon" Corporation by the results of periodic medical examinations over the period from 2011 to 2015, taking into account hygienic conditions of work.
Materials and methods. The paper presents the data on hygienic evaluation of noise, microclimate, lighting and severity and intensity of processes at workplaces. The equipment used was: audiometer "Larson Davis 800 B", globe thermometer "Tensor 41", catatermometer (F 564), light meter "U-116". The results of medical examination of workers of "Obolon" Corporation were analyzed for the period from 2011 to 2015. There were formed 4 occupational groups. The 1–3 groups included operators engaged in bottling who were exposed to intensive industrial noise. The control group was formed of workers, which were not exposed to intensive industrial noise.
Results. It is established that according to the acting "Safety classification on work by indices of harmfulness and danger of work environment factors, intensity and strain of the work process", by noise levels at some work places, conditions of the personnel, engaged in beverage bottling, can be related to Classes 3.1 (harmful conditions of the 1st degree) and 3.2 (harmful conditions of the 2nd degree); by indexes of the air temperature – to work conditions of Classes 2 (permissible), 3.1 (harmful conditions of the 1st degree) and 3.2 (harmful conditions of the 2nd degree); by the indexes of natural and artificial light – to work conditions of Classes 2 (permissible) and 3.1 (harmful conditions of the 1st degree); by indexes of intensity and strain of the work process – to work conditions of Classes 2 (permissible) and 3.1 (harmful of the1st degree). In general, work conditions of the personal, engaged in bottling, can be referred to Class 3.2 (harmful conditions of the 2nd degree). It is established that the number of cases of sensorineural hearing loss and diseases of the cardiovascular system in operators, engaged in bottling, is significantly higher than among the control group.
Conclusions. It is found that in bottling operators, who are exposed to elevated levels of constant, broadband noise, increasing the permissible levels of noise at medium and high frequencies (500–8000 Hz), a significantly higher (P < 0,05) frequency of detection of sensorineural hearing loss and diseases of cardiovascular system have been recorded, as compared with the control group. The results can be explained by the availability of specific and nonspecific effects of noise on the body of employees.
