OSHA jurisdiction — federal, not state plan
Georgia does not operate an OSHA-approved state plan. Most private-sector employers and workers in Georgia fall under federal OSHA jurisdiction, which enforces the standards found in 29 C.F.R. Parts 1903, 1904, 1910 (general industry), 1926 (construction), and related federal workplace safety regulations. State and local government workers in Georgia are not covered by federal OSHA and lack the protections of the OSH Act because Georgia has no state plan extending coverage to public employees.

Workers' compensation insurance coverage requirement
Georgia requires employers with at least three full-time, part-time, or seasonal employees to carry workers' compensation insurance. For incorporated businesses or LLCs, corporate officers or members are included in the three-employee count regardless of whether they exempt themselves from coverage. Specific categories of workers are exempted from the workers' compensation law, including federal government employees, railroad employees, farmers and farm laborers, and domestic servants. Employers obtain coverage through private insurers or State Board–approved self-insurance programs.
