- Proposal for the risk analysis for silica exposure based on the respirable fraction dust Alexander Longas-Restrepo Jhon Édison Toro-Marín Ingeniería TLV Silica exposure respirable fraction similar exposure groups (SEG) Crystalline silica is a natural chemical compound present in rocks, sand and soil. In industry, it is found in chemical products: cement, bricks, concrete... To measure the amount of silica a worker breathes, a dust sample must be taken from the respirable fraction. Due to the cost of chemical analysis of this fraction against silica, whose proportion is approximately 1:25, it is important to establish a methodology that allows an approximation of the risk calculation related to silica exposure, in order to reduce it. According to this, 63 data (2016-2019) were analysed, corresponding to measurements of the aforementioned dust with emphasis on silica belonging to industrial processes. The data were then analysed, and a statistically acceptable relationship was found for different industrial processes, resulting in a mathematical equation to determine the amount of silica, as a function of the amount of respirable fraction, with a statistical acceptance level. 2020 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49663642016 https://www.redalyc.org/journal/496/49663642016/ https://www.redalyc.org/journal/496/49663642016/html/ https://www.redalyc.org/journal/496/49663642016/49663642016.epub https://www.redalyc.org/journal/496/49663642016/movil 10.15446/dyna.v87n212.79882 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.212 Vol.87
