INTEGRATED RISK ASSESSMENT DURING THE MACHINING OF HIGH-TECH COMPOSITE MATERIALS

Abstract

The article determines that there is a significant excess of hygienic regulations of chemicals in the air of the working area during drilling of carbon-containing composites in the standing and sitting positions, as well as during moving and fixing the workpiece. It has been established that the noise load indicators exceed the maximum permissible values during the performance of the corresponding production task, except for the operation of moving and fixing the workpiece, which is directly related to the quasi-brittle structure of this type of composite materials. At the same time, an excess of the vibration level from the operation of the drilling machine was recorded, as well as its compliance with the regulatory values during the movement and fixation of the workpiece. The use of rapid entire body assessment (REBA) showed that lifting, setting and carrying workpieces, as well as drilling holes in the upper standing and sitting positions, is a very high-risk task that requires urgent action to prevent the onset of traumatic events. As a result of the study, it is proposed to use a new approach (Integrated risk assessment, IRA) to obtain an integrated risk assessment during the processing of high-tech composite materials, which takes into account each individual factor in complex interactions.
