OSHA-approved state plans are occupational safety and health programs operated by individual states or territories. These plans must be at least as effective as federal OSHA but may include additional requirements tailored to local industries and hazards.
State plans cover most private sector employers and often include state and local government workers who are not covered under federal OSHA.
In states with OSHA-approved plans, employers should follow state-specific requirements, which may be stricter than federal OSHA standards.
