What are the Regulatory Standards for Silica Dust?
Regulatory standards for silica dust exposure vary by country but generally aim to limit workers' exposure to safe levels. For instance, the Occupational Safety and Health Administration (OSHA) in the United States has set a permissible exposure limit (PEL) of 50 µg/m³ for respirable crystalline silica, averaged over an 8-hour workday. These standards are based on extensive epidemiological research and are designed to minimize health risks.
