The Massachusetts Workplace Safety and Health Program (WSHP) was recognized as an OSHA State Plan in August 2022. WSHP enforces occupational safety and health regulations in public sector workplaces, including: state, county, and municipal workplaces; public schools, colleges, universities, and quasi-government agencies, such as water districts and transportation. Federal OSHA continues to have jurisdiction over private sector.
State Plans are OSHA-approved workplace safety and health programs operated by individual states or U.S. territories. There are currently 22 State Plans covering both private sector and state and local government workers, and there are seven State Plans covering only state and local governments. State Plans are monitored by OSHA and must be at least as effective as OSHA in protecting workers and in preventing work-related injuries , illnesses, and deaths.
