New Hampshire is not a "state plan" state; that is, it does not have a federally approved occupational safety and health regulatory program. Consequently, the federal OSH Act governs occupational safety and health requirements in the private sector workplace. However, the state's Public Employee Safety and Health Law governs safety and health requirements in the public sector workplace. Its requirements are similar to the federal standard.
Under the state Workers' Compensation Act, both public and private sector employers with more than 10 employees in New Hampshire must submit a written safety program biennially to NHDOL. Because New Hampshire is not a state plan state, this requirement does not replace any requirements of the federal OSH Act.
