Analysis of Flour Dust Exposure to Lung Capacity of Flour Mills Workers

Introduction: Optimal lung capacity is essential for worker health and productivity. A dusty work environment can increase the risk of inhaling particles that affect workers' health. Workers in flour mills are at risk of respiratory problems due to exposure to flour dust in the work environment. Objectives: This study aims to analyze the effect of exposure to flour dust on lung capacity in flour mill workers. Methods: This type of research is quantitative research with an analytical observational approach using a cross sectional study design, conducted in October-December 2024. The research sample was 96 respondents consisting workers in the production and non-production department. Data were collected through measurements and questionnaires, then analyzed using univariate, bivariate, and multivariate analysis. Results: The study showed that 80.2% of workers had abnormal lung capacity. Exposure to flour dust (p=0.001), history of lung disease (p=0.006), working department (p=0.003), smoking habits (p=0.004), and use of personal protective equipment (p=0.000) were significantly associated with lung capacity (p<0.05). The variables of age (p=0.865) and lenght of work (p=0.486) are not significant (p>0.05). Multivariate analysis showed that among all the variables studied, the use of personal protective equipment (PPE) and exposure to flour dust had the most influence on lung capacity. Conclusions: The use of personal protective equipment and exposure to flour dust are the variables that most significantly affect the lung capacity. Therefore, we recommend the need to implement occupational safety and health programs such as the provision of adequate ventilation systems, provision of appropriate personal protective equipment (PPE), and periodic assessment of workers' lung capacity.
