NAICS 212321: Nonmetallic Mineral Mining and Quarrying / Mining, Quarrying, and Oil and Gas Extraction
This industry group comprises establishments primarily engaged in mining or quarrying nonmetallic minerals such as crushed stone, sand, gravel, clay, and dimension stone.
Common workplace hazards include respirable crystalline silica exposure, struck-by hazards from heavy mobile equipment, and falls from elevated surfaces at quarry sites. Workers may also face risks from blasting operations, conveyor belt entanglement, and noise-induced hearing loss.
Mining support activities that fall under OSHA jurisdiction (rather than MSHA) must comply with General Industry standards (29 CFR 1910). The distinction depends on whether the work is at a mine site (MSHA jurisdiction) or at a non-mine location. Common OSHA citations include hazard communication (1910.1200), respiratory protection (1910.134), and lockout/tagout (1910.147).
