π¬ Silica dust risks might be higher than OELs suggest
Occupational exposure limits (OELs) might underestimate the health risks in workplaces with silica dust exposure. This study looked at 42 enterprises across Yongchuan District, Chongqing, China, examining 212 silica dust-exposed positions. While 764 samples (72.1%) met OELs, 317 samples (29.9%) were still rated as high or very high risk. This shows OEL compliance alone can miss silica-related health dangers, especially in high free crystalline silica jobs. Combining OEL checks with risk assessment could improve silicosis prevention efforts. π¬
