Silica (SiO₂) is one of the most abundant elements in the Earth's crust, and in its crystalline form, it is toxic to humans, potentially causing silicosis and even cancer with prolonged exposure. This study investigates working conditions in marble workshops in Santarém-PA and the risks of exposure to crystalline silica. The research involved visits to four companies in the sector, using the Ministry of Labor and Employment’s Reference Manual for Marble Workshops as an evaluation tool. The results indicate a lack of worker training and misinformation about occupational hazards. Collective protection measures, such as wet-cutting machines, are adopted but not strictly enforced. Personal protective equipment is provided but not consistently used. The study concludes that exposure to free crystalline silica in the region’s marble workshops is high and poses a significant health risk to workers. It emphasizes the need for surveillance actions and further investigations to improve working conditions and worker health protection.
