Quantitative Risk Assesment of Crystalline Silica Exposure in Ceramics Industry

Abstract

Crystalline silica can be found in Ceramics Industry. Ceramics are basically made of clay, feldspar and silica sand. Ceramics manufacturing process starts from the processing of materials, forming, drying, burning and gazing. Crystalline silica consists of three types of quartz, tridymite and cristobalite which are distinguished by their forming temperature. Crystaline silica dust is very dangerous for health workers are exposed continuously it can cause a silicosis. Prevention and control efforts can be done one of them by conducting a risk analysis study on crystalline silica exposure. In this research will be discussed about the analysis of crystalline silica exposure into production workers in the ceramics industry. The purpose of this study was to assess the risk level of crystalline silica due to silicosis. Subjects in this study were 47 production workers with the exposure to crystalline silica between 0,007-0,4 mg I m 3• From the result of risk analysis, it was found that 42,6% of workers had unsafe risk which was confirmed by radiology examination was 6,4% of workers with abnormal condition. Complaints experienced by workers include shortness of breath, cough and phlegm. Long term exposure to 5-20 years to the next tends to increase the risk of the effects caused by exposure to crystalline silica. Based on the results of this study it is recommended that decision makers take action to implement effective risk management strategies to prevent the long-term effects of crystalline silica exposure to the workplace.

“…The research result (Sahri et al, 2019) showed that 42.6% of respondents have an unsafe risk level of exposure to c-silica dust and potential health problems due to c-silica dust. Based on the estimated calculation of chronic exposure risk, the risk level tends to increase over the next 20 years.…”
