U.S. Occupational Safety and Health Standards-Air contaminants-Mineral Dusts is promulgated by the US OSHA and specifically regulates occupational exposure limits for mineral dust. This table covers mineral dusts such as crystalline silica, amorphous silica, asbestos, coal dust, talc, graphite, and mica. It sets TWA limits in units of millions of particles per cubic foot (mppcf) or mg/m³, establishing separate standards for respirable dust and total dust. It serves as the core legal basis for dust hazard control in industries such as mining, construction, and manufacturing.
