The Michigan Occupational Safety and Health Administration (MIOSHA) is part of the Michigan Department of Licensing and Regulatory Affairs. The main office is located in Lansing, Michigan.


The Michigan State Plan applies to all places of employment in the state, with the exception of federal government workers, the United States Postal Service, maritime and mining activities, and domestic employment, which are subject to OSHA jurisdiction.

Unique State Plan Standards

MIOSHA has adopted most OSHA standards by reference but has a unique Child Labor standard.

Enforcement Programs

The General Industry Safety and Health Division conducts safety and health inspections in all places of employment within the state of Michigan, with the exception of those covered by the Construction Safety and Health Division. The MIOSHA Field Operations Manual (FOM) provides guidance for the enforcement program. Compliance officers inspect workplaces for hazardous conditions and issue citations where violations of MIOSHA regulations are found. Inspections may be the result of regular scheduling, imminent danger reports, fatalities, worker complaints, or referrals. For more information, please visit the Michigan State Plan website.

Voluntary and Cooperative Programs

MIOSHA offers voluntary and cooperative programs that focus on reducing injuries, illnesses, and fatalities. MIOSHA also offers on-site consultation services which help employers comply with MIOSHA standards and identify and correct potential safety and health hazards. For more information on these programs, please visit the Michigan State Plan website.

Informal Conferences and Appeals

MIOSHA management personnel conduct informal conferences in an effort to resolve contested cases. Cases not resolved by informal conferences are placed in contest and referred to the MIOSHA Appeals Division, which hears and rules on appeals from citations.
