Currently, cases of respiratory diseases in civil engineering workers explain a large part of the physical impact of the company that is dedicated to this work. However, one of the main tasks of industrial health and safety is to minimize its harmful effects on the health of workers. The purpose of this measurement is to evaluate the concentration of dust produced in the crushing process of rajón stone, work to which the workers of the company VIASCON S.A.S. are exposed. For this, the gravimetric method was used, which consists of analyzing the amount of an element, in this case the dust present in a sample, in the TSQUEST 3M EVM7 filters placed in the environmental monitor for particulate material, provided by the Industrial Engineering Laboratory. from the University of Córdoba.
