Annual injury summary
OSHA 300A summary — when to post it, who signs it, and who has to file it online
Form 300A, the Summary of Work-Related Injuries and Illnesses, totals your OSHA 300 log for the year. Every employer that keeps a 300 log must complete it, have a company executive certify it, and post it where employee notices go from February 1 to April 30 — even in a year with zero recordable cases. Some establishments must also submit the summary electronically to OSHA by March 2. In a signed-in account, OSHA Scan's injury log totals the 300A from each site's log and prints it in English and Spanish; a company executive still certifies it, and you post it and submit any data to OSHA yourself. Its photo scans check your work areas, including the break room where the summary hangs, for visible hazards like blocked extinguishers and cords near wet floors. The free checklist below covers each step from review to posting.

A once-a-year form that most sites rush in January
The 300A is short — a page of totals, establishment details, and a signature — which is exactly why it gets rushed. The common mistakes are predictable: totals copied from a log nobody reviewed, hours worked that include vacation and holiday pay, a signature from someone who doesn't qualify as a company executive, or a summary that goes up late, comes down early, or ends up covered by newer notices. The rule asks for more than a form on the wall: review the log first, certify that you reasonably believe the totals are correct and complete, and keep the summary posted and legible from February 1 through April 30.
The summary also tells you where to look next. A year of days-away cases from slips in the same building, or strains on the same line, points to the conditions you should be checking every week. The photo scan works separately from the summary. It reviews photos of the areas behind the numbers — and, in this example, the break room where the summary is posted, where the extinguisher sits behind stacked chairs and boxes and a power strip lies on the floor next to a wet spot.
Reading your 300A the way an inspector or customer would
The 300A turns a year of cases into a few numbers, and those numbers become rates. The total recordable incident rate (TRIR) is total recordable cases multiplied by 200,000 and divided by total hours worked; the DART rate uses only days-away and job transfer or restriction cases. As an illustration of the math, an establishment with 4 recordable cases and 180,000 hours worked has a TRIR of about 4.4. The Bureau of Labor Statistics publishes industry rates by NAICS code, so customers and insurers can see how your rate compares — which is why the hours figure matters. Paid vacation, sick leave, and holidays don't count as hours worked, and padding the denominator lowers the rate on paper without making anyone safer.
OSHA reads the same data. Electronically submitted 300A summaries have been used to help select establishments for programmed inspections, and a compliance officer on site will compare the posted summary against the log behind it. A summary certified without a real review, a missing posting at one of several locations, or totals that don't match the log all suggest the records weren't taken seriously. The fix is a short January routine — review, total, certify, post, submit if covered — and a year-round habit of inspecting the places where last year's cases happened.
How to complete and post the OSHA 300A summary
Run through these steps before crews start — each one covers a visible gap the AI can help you catch.
- 1
Review and correct the 300 log
Before totaling anything, check each case on last year's 300 log for recordability, classification, and day counts, and fix errors or missing cases.
- 2
Total the log columns onto Form 300A
Enter the number of deaths, days-away cases, job transfer or restriction cases, and other recordable cases, the total days away and days restricted, and the totals for each injury and illness type.
- 3
Add employees and hours worked
Use the 300A worksheet: the annual average number of employees is the total number paid in all pay periods divided by the number of pay periods, and hours worked leaves out vacation, sick leave, and holidays.
- 4
Have a company executive certify it
The owner of a sole proprietorship or partnership, a corporate officer, the highest-ranking official at the establishment, or that person's immediate supervisor reviews and signs the summary.
- 5
Post it and submit if covered
Post the certified summary where employee notices go from February 1 to April 30, submit it through OSHA's Injury Tracking Application by March 2 if your establishment is covered, and keep it for five years.
What a photo scan adds to your year-end summary
The 300A summarizes last year. A photo scan checks the areas behind those numbers today — including the room where the summary itself is posted.
Fire equipment access
Extinguishers, exits, and alarm pulls blocked by chairs, boxes, or storage — conditions that are easy to miss in a room people use every day.
Electrical and wet floors
Power strips on the floor, cords across walkways, and spills near outlets — shock and slip exposures in a single spot.
Walkways and storage
Boxes and furniture crowding aisles, doors, and the path to emergency equipment.
Dated records year-round
Each scan is time-stamped, so the fixes you make between one summary and the next are documented with a date.

1Fire extinguisher hidden behind stacked chairs and boxes
HighPossibly related to portable fire extinguisher access (29 CFR 1910.157(c)(1))
Observed condition: In a fire, nobody has time to move a stack of chairs; an extinguisher has to be readily accessible and easy to spot.
Corrective action: Move the chairs and boxes away from the extinguisher, keep the space in front of it clear, and mark it so it stays visible.
High confidence
2Power strip lying on the floor next to a wet spot
MediumPossibly related to electrical equipment hazards and floor condition (29 CFR 1910.303(b)(1) and 1910.22(a))
Observed condition: Water near energized equipment adds a shock exposure to the slip hazard, and a floor-level power strip is easy to kick, step on, or soak.
Corrective action: Clean up the water and find its source, unplug the floor-level strip, and mount power where it stays off the floor and away from liquids.
High confidence
3Notices on the board can't be read in the photo — the 300A posting needs a human check
LowPossibly related to annual summary posting (29 CFR 1904.32(b)(5)–(6))
Observed condition: From February 1 to April 30, the certified 300A has to hang where employee notices go. A photo can't confirm which papers are posted, so this is flagged for review, not as a violation.
Corrective action: During the posting window, confirm last year's certified 300A is on this board, legible, and not covered by newer notices.

Start your injury log freeWhat the AI can and can't detect
OSHA Scan reads a single photo. That makes it fast and easy for anyone on site — but it also means it has real limits. Here's an honest look at both.
What it can catch from a photo
- Fire extinguishers, exits, and electrical panels blocked in the photo
- Cords, power strips, and wet floors that create shock or slip hazards
- Clutter and storage crowding walkways and doors
- Whether a visible posting area exists in the photographed room
What a photo can't tell it
- Whether the papers on a notice board include your 300A — postings usually aren't legible in a photo
- Whether your case totals, hours worked, or employee counts are correct
- Whether the summary was certified, or by whom
- Whether your establishment must submit data electronically
OSHA Scan gives an AI-assisted preliminary review from a photo. It does not replace an on-site inspection by a qualified safety professional, and a compliance score is not an official OSHA determination.

Always confirmed by a person on site
A scan is a fast first look, not the final word. Before treating this kind of area as safe, a competent person should still confirm:
- The 300A totals match the reviewed 300 log
- A qualifying company executive signed the certification
- The summary is posted from February 1 to April 30 at each establishment
- Your electronic submission went in by March 2, if your establishment is covered
People also ask
When does the OSHA 300A have to be posted?
From February 1 through April 30 of the year after the year the records cover (29 CFR 1904.32(b)(6)). Post it at each establishment in a conspicuous place where notices to employees are customarily posted, and make sure it isn't altered, defaced, or covered by other material during those three months.
Who can certify the OSHA 300A?
A company executive: an owner of the company (only if it is a sole proprietorship or partnership), an officer of the corporation, the highest-ranking company official working at the establishment, or that person's immediate supervisor (29 CFR 1904.32(b)(4)). By signing, the executive certifies that they examined the records and reasonably believe, based on their knowledge of how the information was recorded, that the summary is correct and complete.
Do I have to post a 300A if we had no injuries?
Yes. If no recordable injuries or illnesses occurred during the year, you still complete the 300A, enter zeros on the total line, have it certified, and post it from February 1 to April 30. A posted zero-case summary tells employees the records exist and were reviewed.
Who has to submit the 300A electronically?
Under 29 CFR 1904.41, establishments with 250 or more employees that must keep injury records, and establishments with 20 to 249 employees in designated industries, submit their 300A data through OSHA's Injury Tracking Application by March 2 each year. Establishments with 100 or more employees in certain designated high-hazard industries must also submit information from their 300 and 301 forms. Check OSHA's injury reporting page for the current industry lists before assuming you're exempt.
Does OSHA Scan fill out or submit my 300A?
It fills in the totals, but it never certifies, posts, or submits anything. The injury log in a signed-in OSHA Scan account totals the 300A from each site's 300 log, collects the average number of employees and total hours worked, records the name, title, and date the executive gives when certifying, and prints the summary in English and Spanish. It also prepares a CSV file in the upload layout OSHA's Injury Tracking Application uses. A company executive still certifies the summary, you post it from February 1 to April 30, and you upload any required data on osha.gov yourself. OSHA Scan is not affiliated with OSHA, and it can't tell whether your summary is posted; that check stays with you. Separately, its photo scans flag visible hazards — like the blocked extinguisher and floor-level power strip in the example above — with a possibly related standard and a corrective action.
