ABSTRACT

A purpose of this research is individual and group occupational risk evaluation at metallizers workplaces of titanium alloys production in the process of covering the titanium half-finished products with aluminum. The occupational risk has been estimated according to the hygienic criteria of Guide "P 2.2.2006-05", "P 2.2.1766-03", the individual occupational risk has been estimated according to the method, elaborated in Research Institute for Occupational Medicine of Russian Academy of Medical Sciences and Klin Institute of Work Conditions and Safety. The authors have established that the labor conditions correspond to the classes 2-3.1 in respect of air temperature, class 3.1--illumination, classes 3.3-3.4--noise. Assessing in general, with account of combined influence of the occupational hazards, the conditions have been attributed to 3-4 degrees of 3 class of harmful working conditions, that conform to the high and very high occupational risk levels. The individual occupational risk of the metallizers is characterized by the gradations from the average to very high one, the integral individual occupational risk for the group of metallizers as a whole has been estimated as the high one. Essential distinctions in the individual occupational risks should be considered while working out improving and rehabilitation actions.
