Always verify: State OSHA rules change. This guide reflects requirements as of 2025. Verify current standards with your state agency or at OSHA.gov before making compliance decisions.

MIOSHA overview

Michigan's occupational safety program — MIOSHA — has jurisdiction over all private and public sector employers in Michigan. Federal OSHA has no enforcement authority in Michigan workplaces. MIOSHA is administered through the Department of Labor and Economic Opportunity (LEO).

MIOSHA standards

MIOSHA has adopted federal OSHA standards with Michigan-specific modifications and has created additional rules in several areas. Michigan employers must check both federal base standards and any MIOSHA modifications or additions.

Injury and Illness Prevention Program

Michigan requires employers to have a written Safety and Health Management Program — similar to California's IIPP requirement. The program must address hazard identification, communication, and correction.

Reporting requirements

Serious injuries must be reported to MIOSHA within 8 hours. Michigan defines 'serious' broadly — it includes any hospitalization for treatment (not just observation), amputation, or loss of an eye. This is similar to federal requirements.

Consultation services

Michigan Occupational Safety and Health Consultation Education and Training (OCET) offers free, confidential on-site consultation for small businesses — separate from enforcement. Similar to federal OSHA's On-Site Consultation Program.

Variance process

Michigan employers who want to use alternative compliance methods must apply to MIOSHA for a variance — the same concept as federal OSHA but through the state agency.
