First Aid vs. Medical Treatment: How to Tell If an Injury Is OSHA Recordable
By Infranoto
A worker cuts their hand on a sheet-metal edge. Someone cleans it, tapes on a butterfly bandage, and they go back to work. Not recordable. If the same cut gets three stitches at urgent care, it goes on the OSHA 300 log.
The injury is identical. What changed is the treatment, and that one distinction decides more recordkeeping questions than anything else in Part 1904. Getting it wrong works against you either way: under-recording is a citation risk, and over-recording inflates your TRIR and DART for no reason. Those rates follow you into customer prequalification, insurance renewals, and OSHA's targeting data.
Here's how OSHA draws the line, where people trip over it, and how to check a specific case quickly.
The rule: first aid is a closed list
Under 29 CFR 1904.7, a work-related injury or illness is recordable if it results in any of the following:
- Death
- Days away from work
- Restricted work or transfer to another job
- Medical treatment beyond first aid
- Loss of consciousness
- A significant injury or illness diagnosed by a physician or other licensed health care professional (for example a fracture, a punctured eardrum, cancer, or a chronic irreversible disease)
The medical treatment criterion trips people up because it's defined by exclusion. OSHA doesn't publish a list of what counts as medical treatment. It publishes a list of what counts as first aid, and anything not on that list is medical treatment. If a treatment isn't on the list, it isn't first aid, no matter how minor it seems.
OSHA's complete first aid list
These are the 14 treatments in 1904.7(b)(5)(ii). If an injury received only these, and nothing else on the criteria list applies, it is not recordable:
- Using a non-prescription medication at non-prescription strength
- Giving a tetanus immunization
- Cleaning, flushing, or soaking wounds on the surface of the skin
- Using wound coverings like bandages, Band-Aids™, or gauze pads, or using butterfly bandages or Steri-Strips™
- Using hot or cold therapy
- Using non-rigid support, such as elastic bandages, wraps, or non-rigid back belts
- Using temporary immobilization devices while transporting a victim (splints, slings, neck collars, back boards)
- Drilling a fingernail or toenail to relieve pressure, or draining fluid from a blister
- Using eye patches
- Removing foreign bodies from the eye using only irrigation or a cotton swab
- Removing splinters or foreign material from areas other than the eye by irrigation, tweezers, cotton swabs, or other simple means
- Using finger guards
- Using massages
- Drinking fluids to relieve heat stress
Who provides the care doesn't matter. First aid given by a physician is still first aid, and stitches put in by the plant nurse are still medical treatment.
Side by side: the common calls
| Situation | First aid (not recordable on its own) | Medical treatment (recordable) |
|---|---|---|
| Cuts | Cleaning, bandages, butterfly bandages, Steri-Strips | Sutures, staples, surgical glue |
| Medication | OTC drug at OTC strength | Prescription drug, or OTC at prescription strength on a clinician's recommendation |
| Sprains and strains | Ice/heat, elastic wrap, non-rigid support | Rigid splint or cast for immobilization, physical therapy, chiropractic care |
| Eye injuries | Irrigation, cotton swab removal, eye patch | Removal with a needle, spud, or other instrument; prescription eye drops |
| Splinters and debris | Tweezers, swabs, irrigation | Removal that needs a cut, an instrument beyond simple means, or anesthetic |
| Immunizations | Tetanus shot | Hepatitis B, rabies, or other vaccines given after exposure |
| Massage | Massage | Physical therapy or chiropractic treatment |
The gray areas that cause the most mistakes
"Prescription strength" applies even to over-the-counter drugs. If a physician or other licensed health care professional recommends an OTC medication at a prescription-strength dose, it counts as medical treatment, even if the worker buys it at the drugstore. OSHA's recordkeeping preamble gives benchmarks such as ibuprofen over 467 mg, diphenhydramine over 50 mg, and naproxen sodium over 220 mg. A clinician's recommendation or written prescription is enough to make the case recordable, even if the worker never fills it.
Diagnostic visits aren't treatment. An X-ray, an MRI, or a doctor's visit just for observation or evaluation is not medical treatment on its own. If the X-ray finds a fracture, though, the case becomes recordable through the "significant diagnosis" criterion, regardless of how the fracture is treated.
Rigid support is the line for immobilization. An elastic wrap is first aid. A rigid splint used to transport someone is first aid. A rigid splint, cast, or other rigid device used to immobilize the injury afterward is medical treatment.
Wound closure is decided by the method, not the size of the wound. A long cut closed with Steri-Strips is first aid. A small cut closed with a single suture or surgical glue is medical treatment.
Recommended restrictions count even if ignored. If a clinician recommends restricted duty or days off and the worker comes in and does their full job anyway, OSHA still expects you to record the case based on the recommendation.
Some cases are recordable no matter how they're treated. Contaminated needlesticks and sharps injuries (1904.8), qualifying hearing loss (1904.10), and work-related tuberculosis infections (1904.11) have their own rules that skip the first aid test.
Check a case in under a minute
When you're looking at a specific incident and want a second opinion, the free OSHA Recordability Checker walks you through work-relatedness, the general recording criteria, and the special cases, then tells you whether the case belongs on the 300 log and whether it counts toward DART. You don't need an account.
Once your log is accurate, the OSHA Incident Rate Calculator turns it into TRIR and DART rates and benchmarks them against your industry. It's worth doing before year-end. Your Form 300A summary has to be posted from February 1 through April 30, and establishments covered by electronic reporting must submit it to OSHA by March 2.
First aid cases are still data
A first aid case doesn't go on the 300 log, but it still tells you something. The cut that only needed a bandage happened at the same edge that will eventually put someone in stitches. The eye flush happened at the same grinder that will eventually send someone to an ophthalmologist. The difference between a first aid case and a recordable is often just luck.
Most safety teams record first aid cases and near-misses somewhere, but those records rarely get analyzed together. Infranoto puts incidents, first aid cases, observations, and corrective actions in one place, and uses AI to find the hazards that keep repeating so you can fix them before the next one becomes a recordable. If you want to see what your own incident history shows, request a demo.
To get crews reporting the small stuff in the first place, our free near-miss reporting toolbox talk is a good five-minute start.
The takeaway
- First aid is a closed list of 14 treatments. Anything not on it is medical treatment, which makes the case recordable.
- The treatment decides, not the injury or the provider. Steri-Strips are first aid and sutures aren't, whether a nurse or a surgeon applies them.
- Watch the gray areas: prescription-strength OTC doses, rigid immobilization, wound closure method, and recommended restrictions are where most recording mistakes happen.
- Diagnostic tests alone don't count, but a significant diagnosis like a fracture does.
- Don't throw away first aid data. It's the earliest warning you have of your next recordable.
