What Maryland requires
- Maryland applies the federal recording and reporting rule with its own changes: a work-related death is reported to MOSH within 8 hours, and an in-patient hospitalization, an amputation involving bone or cartilage loss, or the loss of an eye within 24 hours, by telephone or in person to the MOSH Central Office, by calling MOSH at 1-800-759-6297, or through MOSH's websiteCOMAR 09.12.21.02 A, B (29 CFR 1904.39 as adopted)
- Since June 8, 2026, the size and industry exemptions from injury recordkeeping apply only to private sector establishments: every Maryland public body, whatever its size or industry, records and reports work-related injuries and illnessesCOMAR 09.12.21.02 C (53:11 Md. R. 484, effective 2026-06-08)
- When an accidental injury causes disability for more than 3 days or death, the employer reports it to the Workers' Compensation Commission within 10 days of receiving oral or written notice of the disability or death, and reports an occupational disease disability promptly. The report states whether the injury arose out of and in the course of employment, the time, cause and nature of the injury and disability, and how long the disability will probably lastMd. Code, Lab. & Empl. 9-707
- If the employer was notified of the injury, or knew of the disability or death at the place it happened, the employee's time limit to file a claim does not start running until the employer files its report with the CommissionMd. Code, Lab. & Empl. 9-708 (b)
- An injured employee gives the employer oral or written notice within 10 days of the injury (30 days after a death); written notice gives the employee's name and address and the time, place, nature and cause of the injury in plain language, and is signed. Without notice a claim is barred unless the Commission excuses it for sufficient reason or because the employer was not prejudicedMd. Code, Lab. & Empl. 9-704 ยท Md. Code, Lab. & Empl. 9-706
Reporting to MOSH
A work-related death goes to MOSH within 8 hours, and an in-patient hospitalization, an amputation involving bone or cartilage loss, or the loss of an eye within 24 hours: by phone or in person to the MOSH Central Office, on MOSH's toll-free line, or through MOSH's website. Since June 8, 2026, every public body records and reports these cases regardless of its size or industry; the small-employer and low-hazard industry exemptions now cover only private employers.
Workers' compensation reports and notice
When an injury keeps an employee off work more than 3 days, or causes a death, the employer reports to the Workers' Compensation Commission within 10 days of being told, covering whether it arose from the work, the time, cause and nature of the injury, and the probable length of the disability. Until that report is filed, the employee's time to file a claim does not start, so late reports keep claims open longer.
Employees give notice within 10 days of an injury, orally or in a signed written notice with the time, place, nature and cause. A missed notice can be excused by the Commission.
Common mistakes
- Calling federal OSHA instead of MOSH about a serious injury.
- A public agency skipping injury records because it has few employees.
- Missing the 10-day Commission report after a 4-day absence.
- Leaving the probable duration of disability off the Commission report.
- Assuming a late report shortens the claim window.
