OSHA 301
Verified vs OSHA sources · 2026-10-05
The Injury and Illness Incident Report (Form 301) — the detailed record behind a single recordable case. It captures what happened, the body part affected, the object/substance involved, and the treatment, and must be completed within 7 calendar days of learning of a recordable case. It's the third of OSHA's three recordkeeping forms, alongside the 300 Log and 300A summary.
Also known as: Form 301, incident report

OSHA 301 at a glance
- One 301 per recordable case — the detail behind each 300 Log line.
- Must be completed within 7 calendar days of learning of the case.
- Captures how the injury occurred, the body part, the object/substance, and treatment.
- An equivalent form (e.g., a workers' comp first report) may substitute if it has the same information.
In plain English
The detailed write-up of a single injury — how it happened, what got hurt, what caused it, and how it was treated. One 301 per recordable case, filled out within a week.
What the rule says
“You must use OSHA 300, 300-A, and 301 forms, or equivalent forms, for recordable injuries and illnesses.”
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 1904.29Read on eCFR / OSHA.gov
- 29 CFR 1904.29(a)Read on eCFR / OSHA.gov
Example
After a worker's hand is caught in a machine, the employer completes a 301 within 7 days: it describes the task, that the left index finger was lacerated, that the unguarded gear was involved, and that the worker received sutures — the detail summarized as a single line on the 300 Log.
Why it matters
The 301 is where the story of each injury lives, and it's what OSHA and safety teams use to spot patterns and root causes. Missing or late 301s (or ones lacking the required detail) are recordkeeping violations and also rob you of the data needed to prevent the next incident.
Which form does what
The 300 Log is the running list; the 301 is the detailed report for each individual case; the 300A is the annual summary of totals. The 300 Log and 301 are both due within 7 days of a case; the 300A is posted Feb 1–Apr 30.
The three OSHA recordkeeping forms
| Form | What it is | Timing |
|---|---|---|
| 300 Log | Running list of all recordable cases | Within 7 days of each case |
| 301 Incident Report | Detailed report of a single case | Within 7 days of the case |
| 300A Summary | Year-end totals, certified & posted | Post Feb 1 – Apr 30 |
OSHA 301: frequently asked questions
- How long do I have to complete the OSHA 301?
- Within 7 calendar days of receiving information that a recordable injury or illness has occurred (29 CFR 1904.29(b)(2)) — the same deadline as entering the case on the 300 Log.
- What's the difference between the 300 Log and the 301?
- The 300 Log is a one-line-per-case running list; the 301 is the full incident report for a single case, with details on how it happened, the body part, the object involved, and treatment.
- Can I use my workers' comp form instead of the 301?
- Yes, if the substitute form contains all the same information the 301 requires. OSHA allows an equivalent form (1904.29(a)).

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.
