[Labor hygiene in the fire production of nickel]

Unfavorable hygienic factors, like nickel-containing dust, toxic gases, resinous sublimates, heat and hard physical labor are inherent in the modern production of nickel. A variety of occupational peculiarities results in a higher morbidity of workers. Diseases of the respiratory organs, digestive system, skin and of the subcutaneous cellular tissue are in the lead. Besides, bronchitis, pneumoconiosis, exogenous fibrosing alveolitis as well as neoplasms in the respiratory organs and stomach equally belong to occupational diseases. Preventive schemes of the general occupational and oncological morbidity of workers must rest on a comprehensive set of measures with the introduction of new technological innovations and of raw materials into all nickel-production stages being of primary importance.
