[Assessment of probability of vibration disease caused by local vibration taking into consideration concomitant factors].

The article sets forth a theoretical basis for the evaluation of the probability of vibration disease caused by local vibration, with due account of the concomitant factors and with recommendations with regard to the assessment of the aggravating and normalizing factors. Basing on the original data and medical literature information, the contributors provided formulae and charts for the assessment of vibration disease, risks caused by noise, cold microclimate, physical overload, and cigarette smoking as an individual factor. A concept was proposed with regard to the risk-free dosage. The concept was viewed as a new hygienic and occupational category, which facilitated evaluating the real occupational risk levels for any profession and their consequent minimizing.
