OSHA Recordkeeping and Workers' Comp: Where They Overlap

8/14/2026

The most persistent misunderstanding in injury management is that OSHA recordability and workers' compensation compensability are the same question. They are entirely separate determinations under separate legal standards, made by different parties, for different purposes.

Quick answer: An injury can be OSHA recordable and not compensable, or compensable and not recordable. OSHA recordability turns on work-relatedness plus specific outcome criteria — medical treatment beyond first aid, restricted work, days away, loss of consciousness, or a significant diagnosis. Compensability is a state-law question decided by the carrier.

Why They Diverge

Dimension	OSHA Recordability	WC Compensability
Governing law	Federal OSHA regulations	State workers' compensation statute
Purpose	Injury and illness surveillance	Benefit entitlement
Decided by	The employer	The carrier, and on dispute the state agency
Work-relatedness standard	An event or exposure in the work environment caused or contributed to the condition, or significantly aggravated a pre-existing condition	Arising out of and in the course of employment, per state law
Threshold	Specific outcome criteria	Any covered injury requiring treatment or producing lost time

Note the OSHA work-relatedness standard is broader: "caused or contributed to." An injury may be recordable because work contributed, while the carrier denies compensability under a stricter state causation standard.

The Recordability Decision Sequence

1. Is it an injury or illness? An abnormal condition or disorder.
2. Is it new? Not a continuation of a previously recorded case.
3. Is it work-related? Did an event or exposure in the work environment cause or contribute to it, or significantly aggravate a pre-existing condition? Presumption of work-relatedness applies for conditions resulting from events in the work environment, subject to specific exceptions.
4. Does it meet a general recording criterion? Death, days away from work, restricted work or job transfer, medical treatment beyond first aid, loss of consciousness, or a significant injury or illness diagnosed by a physician or other licensed health care professional.
5. Or does it meet a specific criterion? Certain needlestick and sharps injuries, medical removal, tuberculosis infection, and hearing loss meeting defined shift and level criteria.

The First Aid Line

The distinction between first aid and medical treatment determines recordability more often than anything else. OSHA defines first aid by an exhaustive list — if a treatment is on the list, it is first aid regardless of who provided it or where.

Treatments generally classified as first aid include: non-prescription medication at non-prescription strength, tetanus immunizations, cleaning and flushing wounds at the surface, wound coverings such as bandages and butterfly bandages, hot or cold therapy, non-rigid support such as elastic bandages, temporary immobilization used for transport, drilling a nail to relieve pressure, eye patches, removing foreign bodies from the eye by irrigation or cotton swab, removing splinters by simple means, finger guards, massage, and drinking fluids for heat stress.

Two traps:

• Prescription strength matters. The same medication given at prescription strength is medical treatment even if no prescription was written.
• Rigid supports are medical treatment. A rigid splint or cast is recordable; an elastic wrap is not.

Restricted Work and Job Transfer

A case is recordable if the employee is kept from performing one or more routine job functions, or from working the full workday they would otherwise have worked.

Two clarifications that matter for modified duty programs:

• Restriction on the day of injury alone does not trigger recordability. The count begins the following day.
• If a health care professional recommends a restriction and the employer sends the employee back to full duty anyway, the case is still recordable. The recommendation governs, not the employer's decision.

A note on modified duty: it reduces workers' compensation cost but does not make a case non-recordable. Restricted work is its own recording criterion. Do not design a return-to-work program with the expectation of avoiding OSHA recording — and never pressure a provider to remove restrictions for recordkeeping purposes, which is a serious violation.

The Forms and Deadlines

Form	Purpose	Timing
OSHA 301	Incident report for each recordable case	Within 7 calendar days of learning the case is recordable
OSHA 300	Log of work-related injuries and illnesses	Entered within 7 calendar days; maintained by establishment
OSHA 300A	Annual summary	Posted February 1 through April 30 of the following year
Electronic submission	Submission to OSHA for covered establishments	Annual deadline; covered industry and size criteria have changed — verify current requirements

Retention: logs, summaries, and incident reports must generally be retained for five years following the covered year, and updated as new information about a case becomes available.

Reporting Serious Events

Separate from recording, certain events must be reported directly to OSHA on short deadlines:

• Fatality — within 8 hours
• In-patient hospitalization, amputation, or loss of an eye — within 24 hours

These deadlines are short and strictly enforced. Build them into the incident escalation process, because the person who first learns of a hospitalization is rarely the person who knows the reporting rule.

Common Errors

• Recording based on the workers' compensation determination. Different standards — make the recordability decision independently.
• Not recording restricted work cases because the employee stayed at work.
• Misclassifying prescription-strength medication as first aid.
• Missing the day count — days away and restricted days are counted in calendar days, including weekends and holidays.
• Failing to update a case as more information becomes available.
• Not maintaining logs by establishment where required.
• Missing the 300A posting window.
• Discouraging reporting — policies and incentive programs that deter reporting are independent violations.

Where the Two Systems Genuinely Overlap

• One incident report should capture the facts both systems need.
• The same incident investigation serves both.
• The 300 log is the best injury dataset most employers have. Analyze it by department, task, and injury type to target prevention — which lowers both recordable rates and claim frequency.
• Anti-retaliation. Both systems protect employees who report injuries.

Frequently Asked Questions

If a workers' comp claim is denied, do we remove it from the OSHA log?

Not automatically. Recordability is determined under OSHA's standard. Re-evaluate only if new information changes the work-relatedness analysis.

Is a case recordable if the employee was sent home for the rest of the day?

Restriction or absence on the day of injury alone does not make it recordable. The count starts the next day.

Does modified duty avoid recording?

No. Restricted work is itself a recording criterion.

Are all employers required to keep OSHA logs?

Employers with 10 or fewer employees at all times during the previous calendar year, and establishments in certain low-hazard industries, are partially exempt from routine recordkeeping — but all employers must report fatalities and severe injuries.

Who decides recordability?

The employer, applying OSHA's criteria. It is not the carrier's decision and not the physician's.

Run Both Systems Deliberately

One intake process, two independent determinations, one shared prevention dataset. Employers who conflate the two get both wrong.
