MIOSHA Standards Every Michigan Construction Project Must Follow
Construction plays a central role in economic growth across Michigan, from downtown redevelopment to expanding commercial corridors in Southeast Michigan. But alongside opportunity comes risk.
Because construction remains one of the most hazardous industries in the United States, safety compliance is not optional — it is essential.
In Michigan, contractors must comply with both federal OSHA standards and state-specific regulations enforced by the Michigan Occupational Safety and Health Administration (MIOSHA). As an OSHA-approved State Plan, MIOSHA standards must meet or exceed federal requirements under 29 CFR Part 1926.
Below is a breakdown of the most critical MIOSHA construction standards that every Michigan project must follow.
MIOSHA and Federal OSHA Requirements
MIOSHA operates under Act 154 of 1974, which requires employers to provide a workplace “free from recognized hazards” likely to cause serious injury or death.
MIOSHA regulates:
- Construction health and safety standards
- Worker training and hazard communication
- Injury reporting and recordkeeping
- Emergency response and incident procedures
Routine site inspections can result in fines, work stoppages, or reputational harm if violations are identified.
Fall Protection (MIOSHA Part 45)
Falls are the leading cause of construction fatalities nationwide. MIOSHA’s Part 45 — aligned with OSHA Subpart M — requires fall protection for workers exposed to heights of six feet or more.
Key requirements include:
- Guardrail systems at open edges
- Safety net systems
- Personal fall arrest systems (full-body harnesses and anchorage points)
- Worker training on inspection and proper use
Scaffolding Safety (MIOSHA Part 12)
Scaffolding must meet strict safety requirements, including:
- Supporting at least four times the maximum intended load
- Fully planked platforms
- Guardrails on scaffolds over 10 feet high
- Daily inspection by a “competent person”
- Safe access using ladders, ramps, or stair towers
Improper scaffolding remains a major cause of jobsite injuries, making inspection and structural integrity critical.
Ladder Safety (MIOSHA Part 11)
Ladders are among the most frequently misused tools on construction sites. MIOSHA requires:
- Use of ladders rated for the intended load
- Proper 4:1 angle ratio for extension ladders
- Stable bases (no stacking materials underneath)
- Prohibition against standing on the top cap of stepladders
- Immediate removal of damaged ladders from service
Personal Protective Equipment (PPE) – MIOSHA Part 33
Employers must assess jobsite hazards and provide appropriate PPE at no cost to workers.
Common required PPE includes:
- Hard hats
- ANSI-approved safety glasses
- High-visibility vests
- Steel-toe boots
- Hearing protection
- Respiratory protection
- Cut-resistant gloves
Given the presence of heavy machinery, sharp materials, and airborne dust, PPE remains a fundamental safety requirement.
Hazard Communication (MIOSHA Part 42)
Construction workers must be informed of chemical hazards. MIOSHA requires:
- Proper labeling of hazardous chemicals
- Access to Safety Data Sheets (SDS)
- Worker training on chemical handling
- Written hazard communication plans
These standards apply to materials such as curing agents, adhesives, fuels, and sealants.
Trenching and Excavation Safety (MIOSHA Part 9)
Excavation work carries significant risk of cave-ins. MIOSHA mandates:
- Protective systems (sloping, shoring, shielding) for trenches five feet deep or more
- Safe entry/exit within 25 feet for trenches four feet deep or more
- Daily inspections by a competent person
- Keeping excavated soil and heavy equipment at least two feet from trench edges
Trench collapses are often fatal, making strict compliance critical.
Electrical Safety (MIOSHA Part 17)
To prevent electrocution and fire hazards, MIOSHA requires:
- Ground Fault Circuit Interrupters (GFCIs) for temporary power
- Lockout/tagout procedures during maintenance
- Minimum 10-foot clearance from power lines
- Removal of damaged cords from service
Electrical hazards are particularly common during early site preparation and concrete work involving powered tools.
Why Compliance Matters
Following MIOSHA standards protects workers, reduces legal exposure, and prevents costly project delays. Strong safety practices also enhance company reputation and long-term operational success.
Michigan contractors that prioritize compliance foster safer work environments, strengthen client confidence, and minimize financial risk.
Industry Commitment to Safety
Companies like Merlo Construction emphasize strict MIOSHA adherence across concrete flatwork, excavation, demolition, and large-scale development projects throughout Southeast Michigan.
By integrating experienced supervision, trench shielding systems, PPE enforcement, and consistent safety training, construction firms can maintain both productivity and compliance.
Bottom Line
MIOSHA construction standards are not just regulatory checkboxes — they are life-saving requirements. From fall protection to electrical safeguards, each rule plays a role in ensuring that Michigan’s growth does not come at the expense of worker safety.
For contractors operating in Michigan, understanding and implementing these standards is essential to building responsibly and successfully.
