OSHA 300A
Verified vs OSHA sources · 2026-10-05
The annual Summary of Work-Related Injuries and Illnesses (Form 300A) — the year-end totals from the 300 Log. A company executive must certify it, and it must be posted in the workplace from February 1 through April 30 of the following year. Covered establishments must also submit it electronically to OSHA by March 2.
Also known as: Form 300A, annual summary

OSHA 300A at a glance
- Summarizes the year's totals from the 300 Log (no individual names).
- A company executive must certify it as correct and complete.
- Must be posted February 1 – April 30 of the following year.
- Covered establishments submit it to OSHA's ITA by March 2.
In plain English
The one-page year-end scoreboard of your workplace injuries. A company leader signs it, you hang it where workers can see it (Feb 1–Apr 30), and — if you're a covered employer — you upload it to OSHA.
What the rule says
“At the end of each calendar year, you must: (1) Review the OSHA 300 Log to verify that the entries are complete and accurate, and correct any deficiencies identified; (2) Create an annual summary of injuries and illnesses recorded on the OSHA 300 Log; (3) Certify the summary; and (4) Post the annual summary.”
In context
An enforcement, recordkeeping, or general-duty concept under the Occupational Safety and Health Act and 29 CFR. These terms define how OSHA inspects, cites, and penalizes employers.
Where this is written in OSHA's rules

- 29 CFR 1904.32(a)Read on eCFR / OSHA.gov
Example
For calendar year 2025, an employer totals its 300 Log, has a company executive certify the 300A, posts it from February 1 to April 30, 2026, and — if it has 20+ employees in a covered industry — submits the data through OSHA's Injury Tracking Application by March 2, 2026.
Why it matters
The 300A is the most visible recordkeeping obligation — it must be posted and certified on a fixed schedule, and OSHA verifies both during inspections. Failing to post, posting an uncertified summary, or missing the March 2 electronic submission are straightforward, avoidable citations.
Posting (Feb 1–Apr 30) vs. electronic submission (Mar 2)
These are two separate deadlines. Every covered employer must post the 300A in the workplace from February 1 to April 30. Separately, establishments meeting the size/industry thresholds must electronically submit the 300A (and, for the largest, the 300 and 301 data) to OSHA by March 2.
OSHA 300A — key dates
| Action | When |
|---|---|
| Total the log and have an executive certify it | By February 1 |
| Post the summary in the workplace | February 1 – April 30 |
| Electronically submit to OSHA (if covered) | By March 2 |
| Keep the summary on file | 5 years |
OSHA 300A: frequently asked questions
- When must the OSHA 300A be posted?
- From February 1 through April 30 of the year following the year the records cover, in a conspicuous place where notices to employees are usually posted (29 CFR 1904.32).
- Who has to submit the 300A electronically, and by when?
- Establishments with 20–249 employees in designated high-hazard industries and those with 250+ employees must submit through OSHA's Injury Tracking Application by March 2. The largest covered establishments (100+ in listed industries) also submit 300 and 301 data.
- Does someone have to sign the 300A?
- Yes. A company executive must certify that they examined the 300 Log and that the summary is correct and complete before it's posted.

More OSHA terms
The action an employer takes to fix a cited violation or eliminate a hazard OSHA identified during an inspection. The citation sets an abatement date, the deadline to correct the hazard, and within 10 calendar days after that date the employer must certify to OSHA that the violation was abated. Failure to abate accrues additional penalties of up to $16,550 per day.
Area DirectorThe senior OSHA official in charge of a specific OSHA Area Office — the local unit that runs inspections and enforcement in its geographic territory. The Area Director has the authority to issue citations, propose penalties, hold informal conferences with employers, and approve settlement agreements. When a Compliance Safety and Health Officer (CSHO) completes an inspection, it's the Area Director who ultimately issues the citation.
Bureau of Labor Statistics (BLS)The federal statistical agency within the U.S. Department of Labor that collects, analyzes, and publishes data on workplace injuries, illnesses, and fatalities. BLS conducts the annual Survey of Occupational Injuries and Illnesses (SOII) — compiled from employer OSHA 300 logs — and the Census of Fatal Occupational Injuries (CFOI). SOII data drives OSHA's Site-Specific Targeting (SST) program: establishments whose DART rates significantly exceed their BLS industry average are placed on the SST inspection list.
Competent PersonUnder OSHA's construction standards, a person who is capable of identifying existing and predictable hazards in the surroundings or working conditions, and who has the authorization to take prompt corrective measures to eliminate them. The role requires both knowledge and the authority to act, and is mandated by name in many specific standards — excavations, scaffolds, fall protection, asbestos, and more.
CitationThe formal written notice OSHA issues to an employer after an inspection, describing each alleged violation, the standard cited, the proposed penalty, and the date by which the hazard must be corrected (abated). OSHA must issue a citation with reasonable promptness and no later than six months after the violation occurred.
Closing ConferenceThe meeting at the end of an OSHA inspection where the compliance officer confers with the employer and informally advises them of any apparent violations found. Importantly, the closing conference discusses what was observed and the employer's rights — but it does NOT state final citations or penalties, which come later in the written Citation and Notification of Penalty.
Compliance Officer (CSHO)An OSHA Compliance Safety and Health Officer — the inspector who conducts workplace inspections. A CSHO presents credentials (a photo ID and a serial number), holds the opening conference, performs the walkaround, collects evidence, interviews employees, and recommends citations. CSHOs are either safety specialists or industrial hygienists.
ContestAn employer's formal challenge to an OSHA citation, penalty, or abatement date. To contest, the employer must file a written Notice of Contest with the OSHA Area Director within 15 working days of receiving the Citation and Notification of Penalty. Filing sends the case to the independent Occupational Safety and Health Review Commission (OSHRC); missing the deadline makes the citation a final, un-appealable order.
