OSHA encourages states to develop their own State Plans, provided they are as effective as OSHA’s standards and enforcement. Consequently, Michigan’s State Plan, known as the Michigan Occupational Safety and Health Administration (MIOSHA) and managed by the Michigan Department of Licensing and Regulatory Affairs, oversees safety regulations. MIOSHA covers all state and federal employees and employers, as well as certain private businesses and their workers.
The Michigan State Plan covers the entire public sector as well as a portion of the private sector. However, certain areas remain under federal OSHA jurisdiction, including:
Jobs in the maritime industry
Contract personnel employed by the United States Postal Service (USPS) and facilities operated by USPS contractors
Working conditions for cabin crew members
Employers recognized as members of an Indian tribe who operate businesses within Indian reservation boundaries
Operations, personnel, and employers not covered by MIOSHA fall under federal OSHA authority, which also enforces anti-retaliation protections and oversees inspections to prevent retaliation.
MIOSHA’s enforcement efforts are primarily guided by the Field Operations Manual (FOM). Inspections of the general industry fall under MIOSHA’s General Industry Safety and Health Division, while construction site inspections are conducted by the Construction Safety and Health Division.
Michigan has developed a unique set of standards under MIOSHA for various industries, including the following:
