Comparison: State vs. Federal
• Rules. Pennsylvania is not a "state-plan" state, which means its occupational safety and health program has not been approved by federal OSHA. Therefore, in the private sector (private businesses and nonprofit organizations), the federal law preempts state laws regarding safety and health. For further details, see the national section HAZARD COMMUNICATION STANDARD.
Public sector (state and local government offices and operations) workplaces must follow state hazard communication rules, which have adopted rules that mirror federal requirements and several provisions that are stricter than federal rules.
• Administration and enforcement. OSHA administers and enforces safety and health requirements in private sector workplaces. DLI administers and enforces all safety and health requirements in public sector workplaces.
