The Standalone Trigger
29 CFR 1904.7(b)(7) requires that any significant work-related injury or illness diagnosed by a physician or other licensed health care professional be recorded — even if it does not produce death, days away, restricted work, transfer, medical treatment beyond first aid, or loss of consciousness.
The trigger is the diagnosis itself. A worker who fractures a rib in a workplace fall, declines treatment, returns to full duty the next day, and takes no more than over-the-counter ibuprofen still has a recordable case the moment a physician documents the fracture on imaging.
Why this exists: The general criteria of 1904.7 reflect severity through outcome (death, lost time, treatment). Some clinically significant diagnoses do not consume those resources but still represent meaningful workplace harm. The (b)(7) trigger captures them.
- Work-related cancer. Mesothelioma after asbestos exposure, leukemia after benzene or radiation exposure, bladder cancer in aromatic amine industries, lung cancer in radon-exposed miners. The latency is often decades, but the case becomes recordable on diagnosis if the workplace contribution can be established.
- Chronic irreversible disease. Berylliosis, silicosis, asbestosis, hypersensitivity pneumonitis, chronic beryllium disease, hard metal lung disease. The rule explicitly lists berylliosis as its example.
- Fractured or cracked bone or tooth. A non-displaced rib fracture, a hairline metatarsal fracture, a chipped tooth from a struck-by event. No treatment is required for recordability — the radiologic or clinical diagnosis is enough.
- Punctured eardrum. From acoustic trauma, blast injury, or a foreign body. Recordable on otoscopic confirmation, even when the perforation is expected to heal spontaneously.
These examples are illustrative, not exhaustive. The general standard — significant diagnosis by a licensed professional — captures other diagnoses that meet the same level of clinical importance.
What “Diagnosed by a Physician” Means
The diagnosing professional must be a physician or other licensed health care professional. OSHA defines that category in 29 CFR 1904.46 as a person who is operating within the scope of practice of a license, registration, or certification permitted under U.S. federal or state law.
In practice, the following can render a recordable diagnosis under (b)(7):
- Physicians (MD, DO)
- Physician assistants and nurse practitioners
- Audiologists for hearing-related diagnoses
- Dentists for dental injuries
- Psychologists and psychiatrists for diagnoses within their scope (mental illness)
Self-diagnosis, employee self-report without provider confirmation, and lay observations do not satisfy (b)(7). The entry point to recordability is the professional's documented diagnosis.
Imaging findings counted as diagnoses: A radiologist's read of a hairline fracture, an audiologist's confirmation of a noise-induced threshold shift, an oncologist's pathology report — each is a diagnosis once documented in the medical record.
Work-Relatedness Determinations
Significant diagnosis cases still require a work-relatedness finding under 29 CFR 1904.5. For acute diagnoses (a rib fracture from a workplace fall, a punctured eardrum from a blast at the worksite), causation is usually direct and documented in the incident timeline.
For chronic disease and cancer, work-relatedness analysis is more nuanced and frequently requires:
- A documented occupational exposure history of sufficient intensity and duration.
- A diagnosis pattern consistent with the suspected occupational cause (e.g., mesothelioma localized to pleura in asbestos exposure).
- Plausible biological mechanism per published occupational medicine literature.
- Consideration of competing non-occupational causes — smoking history for lung cancer, family history for leukemia, environmental sources for benzene.
When the work environment contributed in a meaningful way, even alongside non-occupational factors, the case is work-related. The contribution standard does not require occupational exposure to be the sole cause.
Latency and the Year of Recording
Long-latency illnesses are recorded in the year the case is diagnosed and determined to be work-related, not the year the exposure occurred. A retired pipefitter diagnosed with mesothelioma during their post-retirement follow-up is recordable by the former employer if the case is identified during the five-year retention window for the relevant calendar year of last exposure — but more commonly the case is reported via state workers' compensation channels rather than the OSHA log because retention has expired.
Active employees diagnosed today with a chronic disease attributable to their current or prior work at the same employer should be recorded in the current year. Update any prior 300 Logs only if those records are still within the five-year retention window and a previously unrecorded case is uncovered.
Practical Examples
Hairline rib fracture, full duty next day
A warehouse worker is hit in the chest by a falling pallet. The worker is evaluated, X-ray confirms a non-displaced anterior rib fracture, OTC ibuprofen is recommended, no work restrictions. Recordable as an injury with a checkmark in “other recordable cases” — the diagnosis alone triggers recording.
Chipped molar, dental glass repair
An employee bites down on debris in a meal during the work shift, chipping a molar. Dentist documents a cracked tooth and applies dental composite. Recordable as an injury under (b)(7), even though the composite application is debatable as medical treatment independently.
Punctured eardrum from acoustic event
A maintenance technician working near a high-pressure discharge experiences ear pain. ENT examination shows a small tympanic perforation expected to heal. No treatment beyond observation. Recordable as an illness/injury hybrid — typically logged as injury with a (b)(7) trigger.
Common Mistakes
Excluding cases with no medical treatment. A diagnosis can stand alone. No treatment, no days, no restriction does not exclude (b)(7) cases.
Treating “possible” or “suspected” as a diagnosis. A confirmed diagnosis is required. Differential considerations or rule-outs are not the trigger.
Skipping cancer and chronic disease cases because the exposure was years ago. Latency does not erase work-relatedness. Active employees diagnosed during the current year with a work-related chronic disease are recordable in the current year.
Treating an athletic-trainer or unlicensed-aide diagnosis as authoritative. The diagnosing professional must operate within a scope of practice that authorizes diagnosis. Athletic trainers in many states do, but the title alone does not establish it.
Treating “sprain/strain” diagnoses as automatically (b)(7) significant. Routine soft-tissue diagnoses are recordable only if they meet a 1904.7 threshold (treatment, days, restriction, transfer). They are not significant diagnoses for (b)(7) purposes on their own.
