What does "non plan states" refer to in relation to OSHA regulations?

The term "non plan states" in relation to OSHA regulations refers to states that have not adopted OSHA regulations at all. This means that these states do not have an approved Occupational Safety and Health plan and, as a result, are regulated directly by federal OSHA standards. This is significant because it indicates that the federal government, through OSHA, enforces safety and health regulations within these states. On the other hand, plan states have their own occupational safety and health programs that have been approved by federal OSHA and can set different standards, as long as they meet or exceed federal OSHA requirements. Understanding the distinction between non plan states and plan states is essential for fire service personnel to comprehend the regulatory environment in which they operate and ensure adherence to safety standards.
