Physiological and hygienic characteristics of working conditions in the copper and nickel-processing industry]

Basing on complex physiological and hygienic studies, the contributors propose an assessment of the work load of those engaged in the major professions in copper and nickel metallurgy. The results of the study revealed a significant functional overstrain in workers, which resulted from manual labour overload, unfavourable microclimate conditions (hot in summer and cold in winter), along with a set of hazardous factors (dusts, toxic gases, etc). A set of health-related measures was proposed.     

Physiological and hygienic characteristics of working conditions of bus drivers in the Tadzhik SSR]

In warm seasons of the year, the major unfavourable factors in the labour conditions of bus-drivers engaged in local and transrepublican bus routes were heating microclimate, neuropsychic and physical overload, excessive noise levels. The unsatisfactory labour conditions resulted into strain and overstrain of the thermoregulatory function and cardio-vascular system, decreased working capacity and increased fatiguability, as well as in development of nonspecific pathology in the drivers. Improving of the labour conditions should include measures towards optimization of the microclimate and modernization of the cabin's design, rationalization of the labour regimen and improvement of services on the roads.     

Complex hygienic evaluation of working conditions and environmental protection at glass works

The working conditions and sanitary-and-hygienic state of the Kvarts glass works in the town of Kuvasai were studied. Harmful industrial factors were shown to influence on the incidence of disease with temporary disability; atmospheric emission of pollutants and discharge of sewage were calculated. The results of the analysis were assessed in the hygienic point and necessary recommendations to improve working conditions and the environment.
