Evaluation of the occupational risk index of the forest faller

Abstract

The purpose of the work is to assess the professional risk index of a forest feller, taking into account: ergonomic, psychosocial and hygienic factors and individual parameters, with the development of practical recommendations for reducing diseases of the musculoskeletal system, taking into account the adaptive capabilities of a person.To estimate the occupational risk index, methods were used to determine the danger from the working posture, the influence of psychosocial factors, and individual indicators. The assessment of the index of occupational risk of injury/disease of the musculoskeletal system was determined on a scale from 0 to 1. To determine the adaptation capabilities of forest loggers to resist physical exertion, we used the method proposed by R.M. Baevsky.A procedure has been developed for the assessment of the occupational risk index during the performance of various logging operations of a forest logger based on the assessment of ergonomic posture, the influence of psychosocial, hygienic factors, and individual parameters. It was determined that the work related to the technological process of harvesting wood and cleaning trees from branches and knots has the highest degree of risk. It is shown that the greatest influence on the value of the occupational risk index is caused by an uncomfortable ergonomic posture and a psychosocial factor, while when whipping whips and their loading – psychosocial and hygienic factors. It has been established that the greatest influence on the adaptive capabilities of a forest feller has an uncomfortable working posture and a psychosocial factor.The relationship between adaptation possibilities and the discomfort of the working posture, psychosocial and hygienic factors has been established.It is shown that for the felling of trees and sawed off branches, it is necessary to provide workers with high adaptability, while it is desirable to involve workers with low adaptability in the trawling of whips and their load.
