The Michigan OSHA is increasing its focus on excavation safety this month to address one of the construction industry's most persistent hazards. The initiative aligns with a regional federal OSHA effort to mitigate risks associated with trenching and excavation.
Cave-ins remain a primary concern for safety officials, alongside risks such as asphyxiation, toxic fumes, and underground utility strikes. To combat these hazards, MIOSHA is providing education and outreach to help employers recognize soil instability and apply proven prevention methods.
State officials emphasize that protective systems, such as shoring or shielding, are required for any trench five feet deep or deeper. Furthermore, a competent person must inspect these sites daily to identify hazards and ensure soil stability. Professional engineering approval is required for any excavation exceeding 20 feet in depth.
The outreach includes a technical seminar, "Excavations: The Grave Danger," which covers soil classification and the responsibilities of competent persons. MIOSHA also offers free, voluntary consultation services, including hazard surveys and on-site training, to help employers identify risks without the threat of citations or penalties.
These efforts lead into the 2026 Trench Safety Stand-Down scheduled for June 15–19. The national event, held in partnership with the National Utility Contractors Association, encourages worksite training and open dialogue to reduce the number of serious injuries and fatalities in the industry.
