Analysis and assessment of safety during operation of the shot blasting machine in the foundry

Abstract

Introduction. The article discusses the harmful factors of foundry production. The authors analyze and evaluate the workplace of the operator of the shot blasting chamber and offer technical solutions to improve working conditions and reduce the development of occupational diseases.Problem Statement. The objective of this study is to assess the impact of noise and dust pollution on the production sites of the foundry.Theoretical Part. In the course of the study, the most polluted areas were identified with the exceeding permissible values of the considered indicators of noise level and dust content. These are the areas of shake-out grids and casting cleaning. Measures to improve the situation were proposed, such as: organization of acoustics taking into account the characteristics of the production room (acoustic screens, soundproof partitions), a suitable sound absorption area of the premises, the improvement of sound absorption by upgrading the body of the shot blasting chamber.Conclusions. The results of the analysis indicate a sufficiently high level of influence of harmful production factors on the operators of the shot blasting section of the foundry and the need to strengthen labor protection in this area.
