Why You Need a OSHA Form 300A - Summary of Work-Related Injuries and Illnesses
The requirement to complete and post OSHA Form 300A - Summary of Work-Related Injuries and Illnesses is a federal mandate under the Occupational Safety and Health Act of 1970 (OSH Act) and its recordkeeping regulations (29 CFR 1904). This requirement applies directly to all qualifying establishments in Warren, Michigan, as MIOSHA, the state agency responsible for enforcing the federal OSH Act within the state, adopts these federal standards. For restaurant owners, this means compliance is monitored by the Michigan Occupational Safety and Health Administration (MIOSHA). The core rule is that covered employers with 10 or more employees in most industries must record, summarize, and post these forms annually.
Failing to properly complete, certify, and post the OSHA Form 300A from February 1 to April 30 each year triggers significant penalties and operational risks. Based on MIOSHA's adoption of federal penalty structures, violations can result in:
- Substantial fines: As noted, serious violations carry a penalty of up to $16,131 per violation, willful violations up to $161,323, and failure to correct cited hazards can incur daily penalties of $16,131 until abated.
- Increased scrutiny and inspection risk: A failure to post the summary is a visible violation that can prompt a MIOSHA inspection, potentially uncovering other compliance issues leading to additional citations and fines.
- Insurance and legal consequences: Inaccurate or missing records can complicate workers' compensation claims, lead to higher insurance premiums, and provide damaging evidence in personal injury lawsuits, jeopardizing both finances and operational continuity.
Legal code: Occupational Safety and Health Act of 1970 (OSH Act)
Recent update: The penalty amounts for OSHA violations, adopted by MIOSHA, are adjusted annually for inflation; the figures cited reflect increases that took effect in January 2024.
Who Needs a OSHA Form 300A - Summary of Work-Related Injuries and Illnesses?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | OSHA requires all private-sector employers with 10 or more employees in most industries, including food service, to post the Form 300A summary annually if they are not specifically exempt (29 CFR 1904). |
| Bar / Nightclub | Required | Bars and nightclubs are typically covered under the same OSHA recordkeeping rule (29 CFR 1904) as restaurants, making the annual Form 300A posting mandatory for those with 10+ employees. |
| Food Truck | Not Required | This requirement is based on the number of employees, not the mobile nature of the business; a food truck operation with 10 or more employees at any point in the previous calendar year is required to post Form 300A (29 CFR 1904.1(a)). |
| Coffee Shop / Café | Required | If the coffee shop employs 10 or more people, it must comply with OSHA's annual Form 300A posting requirement per the standard recordkeeping regulations (29 CFR 1904). |

164 of 198 auto-filledTotal number of recordable injuries and illnesses
textEnter the total number of work-related injuries and illnesses recorded on your OSHA Form 300 Log for the entire year, as required by OSHA's recordkeeping rule (29 CFR 1904.32).
COMMON MISTAKE: Entering the number from only one month or quarter, or counting incidents that are not recordable under OSHA rules, like first aid-only cases.
Total hours worked by all employees (for total rate calculation)
textEnter the total number of hours worked by all employees at this establishment during the year, which is used to calculate the Total Recordable Case Rate.
COMMON MISTAKE: Using payroll hours instead of actual hours worked (including overtime), or forgetting to include hours for all employees, including temporary and part-time staff.
Total recordable case incidence rate
textThis field should contain the calculated Total Recordable Case Rate (TRCR), derived using the formula [(N x 200,000) / H] where N is the total injuries/illnesses and H is total hours worked.
COMMON MISTAKE: Manually entering an incorrect or rounded figure instead of using the precise OSHA formula, or leaving it blank because the calculation is not understood.
Number of DART cases (days away, restricted, or transferred)
textEnter the total number of cases from your OSHA 300 Log that resulted in days away from work, restricted work activity, or job transfer (sum of columns H and I).
COMMON MISTAKE: Miscounting cases that fall into both columns H and I, or including cases that only involved medical treatment beyond first aid without lost/restricted days.
Total hours worked by all employees (for DART rate calculation)
textEnter the total hours worked by all employees for the year; this figure is used specifically to calculate the DART (Days Away, Restricted, or Transferred) rate.
COMMON MISTAKE: Using a different total hours figure here than the one used for the Total Recordable Case Rate, creating an inconsistency that triggers a review.
DART incidence rate
textThis field should contain the calculated DART rate, using the formula [(Number of DART cases x 200,000) / Total hours worked] as defined by OSHA.
COMMON MISTAKE: Calculating the rate incorrectly or transposing numbers from the TRCR field, which is a common data-entry error for manually prepared forms.
Log Year
textEnter the calendar year (e.g., 2026) for which the injury and illness data is being summarized on this Form 300A.
COMMON MISTAKE: Entering the current filing year instead of the year the log data covers, or using a fiscal year instead of the calendar year.
Establishment Name
textEnter the official, full legal name of the restaurant establishment as it is recognized for business and tax purposes.
COMMON MISTAKE: Using a DBA (Doing Business As) name that differs from the legal entity name on file with OSHA or state authorities.
City
textEnter the city where the restaurant establishment is physically located and where the reported employees worked.
COMMON MISTAKE: Entering a corporate headquarters city or a mailing address city that is different from the physical work location's city.
State
textEnter the two-letter postal abbreviation for the state (e.g., MI) where the restaurant establishment is physically located.
COMMON MISTAKE: Spelling out the full state name instead of using the two-letter abbreviation, which can cause processing delays in electronic systems.

Top 5 OSHA Form 300A - Summary of Work-Related Injuries and Illnesses Mistakes
1. Incorrectly Calculating Total Annual Employee Hours
Entering an estimate, using only payroll data that excludes part-time hours, or miscalculating the sum of hours for all employees (including owners and supervisors) for the entire calendar year. Michigan OSHA (MIOSHA) uses this figure to calculate your establishment's injury/illness rate, and an error here is a common red flag for data integrity, potentially triggering a records review. Avoid by summing the hours worked for every employee from your payroll or timekeeping records for the year—for example, 10 full-time employees at 2,000 hours each (20,000 hrs) plus 2 part-time employees at 1,000 hours each (2,000 hrs) equals a total of 22,000 hours.
2. Failing to Certify the Form
Submitting the Form 300A without the signature of a company executive (owner, CEO, highest-ranking official at the establishment) and the date in the certification section. An uncertified form is considered incomplete and violates 29 CFR 1904.32(b)(3), which can result in a citation and fine from MIOSHA during an inspection. To avoid, ensure the highest-ranking official physically present at your Warren restaurant reviews the data and signs and dates the form before it is posted and submitted electronically to MIOSHA.
3. Posting or Submitting the Wrong Year's Summary
Posting the summary for the previous calendar year (e.g., posting 2023 data in 2024) or mixing data from different years. The OSHA Form 300A is an annual summary for a specific calendar year (Jan 1 – Dec 31) and must be posted from February 1 to April 30 of the following year. Using incorrect data misrepresents your workplace safety record and is a direct violation of posting requirements. Always double-check that the year printed on the Form 300A header matches the data year you are summarizing before posting and electronic submission.

Timeline: Annual Reporting Cycle
Compile Injury & Illness Data from OSHA Form 300
Review your OSHA Form 300 (Log of Work-Related Injuries and Illnesses) for the previous calendar year (January 1 – December 31). Transfer totals for each category (e.g., number of fatalities, injuries requiring days away from work, job transfer, or restricted work activity) into the summary. You must have the Form 300 completed and certified by a company executive as accurate before creating the 300A. Incomplete or uncertified logs are the most common reason for citation during an OSHA inspection.
Complete and Certify OSHA Form 300A
Fill out all sections of the OSHA Form 300A, including the establishment and industry information, and the numbered data columns for the calendar year. A company executive (like the owner or highest-ranking official at the establishment) must sign and certify that the information is true and complete. The form requires specific calculations for total hours worked by all employees; an error here is a frequent audit trigger. ApronPrep's auto-fill can populate establishment data and guide calculations.
Post the Summary for Employee Review
You are required to post the completed and certified OSHA Form 300A in a conspicuous place where all employees can see it, such as a common area or break room. This posting must occur annually from February 1 through April 30. The form must remain posted for the entire 3-month period. Failure to post, or posting outside this mandated window, can result in an OSHA citation and penalty, even if you have no recordable incidents.

See All RequirementsThe timeline for completing and posting your OSHA Form 300A varies and is not a submission-based approval process. According to federal OSHA regulations (29 CFR 1904.32), you must compile the summary from your OSHA Form 300 log by February 1st and post it in a conspicuous location from February 1st through April 30th each year. There is no government processing time for receipt, as this is an internal record-keeping and posting requirement.
The required OSHA Form 300A itself has a government filing fee of $0–$0, as confirmed by the Occupational Safety and Health Administration (OSHA) fee schedule. You can download the form for free from the OSHA website. However, fines for non-compliance can be significant, so accurate completion is critical, much like ensuring your City Business License/Registration is current to avoid local penalties. Not legal advice — verify current requirements with OSHA.
No, the OSHA Form 300A is not transferable; it is a location- and year-specific summary of injuries and illnesses for each establishment. If you move your business to a new Warren address, you must create a new, separate OSHA Form 300 log and subsequent 300A summary for that new location. This is similar to how a new Certificate of Occupancy is required for a new commercial space. The data does not transfer.
You must create and post a new OSHA Form 300A annually, as mandated by OSHA standard 29 CFR 1904.32. The annual cycle requires you to summarize the previous calendar year's data from your OSHA Form 300 log and post the new summary from February 1st to April 30th. Unlike a license with a multi-year cycle, this is a recurring, yearly obligation for covered employers.
During an OSHA inspection, a compliance officer will request to see your past five years of OSHA Forms 300, 300A, and 301 (or equivalent). They will verify that the 300A summary was properly posted during the annual posting period and check for accuracy against the detailed log. Inaccuracies or failure to maintain/post these records can result in citations and fines, as outlined on the OSHA enforcement website.
