INFLUENCE OF DUST FORMATION DURING MECHANICAL PROCESSING OF CARBON-CARBON COMPOSITES ON THE RISK OF OCCUPATIONAL DISEASES

Abstract

Purpose. Establishing the regularities of slime and dust formation during the mechanical processing of carbon-carbon composites in the context of creating a safe working environment for workers in the machine-building industry. Design/methodology/approach. The comprehensive research carried out is important as an integrated method of assessing and forecasting the impact of factors of mechanical processing of carbon-carbon composite materials on the health of workers in the context of developing possible ways to eliminate their negative impact. Factors affecting the nature and severity of the reaction of lung tissue to carbon dust are defined as: concentration of dust, intensity of its exposure, duration of contact; individual sensitivity to dust and the presence of factors that attract the development of fibrosis; nature of dust, geometrical dimensions of particles and aerodynamic properties. Conclusions. A list of occupational health and safety recommendations is offered. A list of occupational health and safety recommendations is proposed. Limitations/consequences of research. The proposed recommendations are universal and can be used in various areas of business to create safe and harmless working conditions in production. Practical consequences. The developed recommendations reduce the risk of occupational diseases. Originality/meaning. According to the conducted research, it was established that dusts of mineral substances are dangerous due to their shape, which makes it difficult to remove them from the lungs. This applies, in particular, to carbon fiber particles released during the cutting of tape or fabric, grinding or cleaning of composite materials.
