## What you need to know

Michigan runs an OSHA-approved State Plan, MIOSHA, covering most private-sector and state and local government workplaces. Many MIOSHA standards differ from federal OSHA, including fire equipment, electrical hazards and construction telecommunications.

## Potentially affected

Michigan employers, facility managers and contractors, including low-voltage, security and IT installation crews working on construction and occupied sites in Michigan.

## DSE recommendation

DSE recommends checking the MIOSHA standard first whenever a Michigan site plan, method statement or safety procedure cites a federal OSHA rule.

## Article

Michigan runs an OSHA-approved State Plan, MIOSHA, covering most private-sector and state and local government workplaces. Many MIOSHA standards differ from federal OSHA, including fire equipment, electrical hazards and construction telecommunications.

## Source facts

According to [OSHA’s Michigan State Plan page](https://www.osha.gov/stateplans/mi), the Michigan Occupational Safety and Health Administration (MIOSHA), part of the Michigan Department of Labor and Economic Opportunity, administers the plan. It applies to private-sector workplaces in the state, with listed exceptions such as maritime employment, and also to state and local government employers, but not to federal government employers.

OSHA states that MIOSHA has adopted many OSHA standards by reference, while a long list of MIOSHA requirements differs from federal standards. The list for general industry includes fire equipment, electrical hazards, confined spaces and signs and tags, and the construction list includes telecommunications, electrical hazards, stairways and ladders, and lock-out/tagout under hand power tools.

MIOSHA’s divisions inspect general industry and construction sites, and inspections can follow regular scheduling, imminent-danger reports, fatalities, worker complaints or referrals. MIOSHA also offers on-site consultation to help employers comply.

## Applicability

Use this for any work performed in Michigan, including when a national procedure, client policy or earlier DSE Updates article cites a federal OSHA standard. OSHA notes that federal OSHA still covers issues the State Plan does not.

## DSE recommendation

DSE recommends checking the MIOSHA standard first whenever a Michigan site plan, method statement or safety procedure cites a federal OSHA rule. For security and low-voltage work, compare the MIOSHA construction telecommunications, electrical and ladder requirements with the procedure in use, record which state standard governs each task, and keep that reference in the job file.

## Verification

For a sample of recent Michigan jobs, confirm the job file names the applicable MIOSHA standard rather than only a federal citation, and that crew training records cover the state requirement. Re-check the comparison when MIOSHA amends a listed standard.
