Abstract

Background: Exposure to Hydrochloric Acid in industrial units can be associated with risks to the human respiratory system. The aim of this study was to investigate the Respiratory Symptoms and pulmonary dysfunction caused by exposure to Hydrochloric Acid washing unit of a steel industry. Methods: This cross-sectional study was performed in a single Acid Washing unit of a steel industry in 2017. The exposed group included 45 male workers and a reference group of 41 unexposed office employees. A questionnaire was used to collect personal and occupational data and a pulmonary function test was conducted with the supervision of an occupational medicine specialist. Pulmonary function parameters included FVC, FEV1 and FEV1/FVC. T-test and chi-square test were used to analyze the data in SPSS. The significance level in this study was defined as less than 0. 05. Results: All lung function parameters in exposed subjects were lower than the reference group and this difference was statistically significant for FVC and FEV1 parameters (p<0. 05). Respiratory Symptoms were more prevalent in the exposed subjects than non-exposed (p>0. 05). Based on the results of the regression model, exposures to Hydrochloric Acid increased the chance of these symptoms by up to 7. 4 times. Conclusion: This study showed that exposure to Hydrochloric Acid alone could increase the risk of Respiratory Symptoms and pulmonary function disorders. Therefore, risk management should be considered for the exposure to this chemical compound.
