Take the courseA fatality, injury or illness is recorded when it is:
Reference: 29 CFR 1904.0 · 29 CFR 1904.1(a)(1) · 29 CFR 1904.1(a)(2) · 29 CFR 1904.2(a)(1) · 29 CFR 1904.4(a)
A case is work-related if an event or exposure in the work environment caused or contributed to it, or significantly aggravated a pre-existing injury or illness. When it happens in the work environment, work-relatedness is presumed unless one of the listed exceptions specifically applies.
The work environment is the establishment and other locations where employees are working or are present as a condition of their employment.
Part 1904 lists a set of exceptions. For example, a case is not work-related when:
Check the full list in 1904.5(b)(2) before you decide a case is not work-related.
Reference: 29 CFR 1904.5(a) · 29 CFR 1904.5(b)(1) · 29 CFR 1904.5(b)(2) · 29 CFR 1904.5(b)(2)(iv) · 29 CFR 1904.5(b)(2)(vii) · 29 CFR 1904.5(b)(2)(viii)
A case is new if:
For occupational illnesses whose signs or symptoms can recur or continue without a new workplace exposure, record the case only once.
Reference: 29 CFR 1904.6(a) · 29 CFR 1904.6(b)(1)
A work-related new case is recordable if it results in any of these:
Some cases have their own rules. For example, you must record all work-related needlestick and cut from a sharp object contaminated with another person's blood or other potentially infectious material. Hearing loss, tuberculosis and medical removal cases also have their own sections in Part 1904.
Reference: 29 CFR 1904.7(a) · 29 CFR 1904.7(b)(6) · 29 CFR 1904.7(b)(7) · 29 CFR 1904.8(a)
First aid alone does not make a case recordable. Part 1904 gives a complete list of what counts as first aid. Treatment that is not on the list is medical treatment, except visits solely for observation or counseling and diagnostic procedures (see below). Examples:
| First aid (not recordable by itself) | Medical treatment (recordable) |
|---|---|
| Non-prescription medication at non-prescription strength | A non-prescription medication recommended by a physician or other licensed health care professional at prescription strength |
| Tetanus shot | Other immunizations, such as hepatitis B or rabies vaccine |
| Cleaning, flushing or soaking surface wounds; bandages, butterfly bandages or Steri-Strips | Sutures, staples and other wound-closing devices |
| Elastic bandages, wraps, non-rigid back belts; hot or cold therapy | Devices with rigid stays or other systems designed to immobilize the body |
| Removing something from the eye using only irrigation or a cotton swab | Other ways of removing a foreign body from the eye |
| Massage | Physical therapy or chiropractic treatment |
The rest of the first aid list: temporary immobilization devices while transporting an accident victim (such as splints, slings, neck collars or back boards); drilling a fingernail or toenail to relieve pressure, or draining fluid from a blister; eye patches; removing splinters or foreign material from areas other than the eye by irrigation, tweezers, cotton swabs or other simple means; finger guards; and drinking fluids for relief of heat stress.
Visits solely for observation or counseling, and diagnostic procedures such as x-rays and blood tests.
Reference: 29 CFR 1904.7(b)(5)(i) · 29 CFR 1904.7(b)(5)(ii) · 29 CFR 1904.7(b)(5)(iii) · 29 CFR 1904.7(b)(5)(iv) · 29 CFR 1904.7(b)(5)(v)
Equivalent forms are allowed.
Enter each recordable case on the 300 Log and the 301 within 7 calendar days of receiving information that a recordable case occurred.
Record cases for employees on your payroll, and also for workers not on your payroll (such as temps) if you supervise them day to day.
For these cases, write "privacy case" instead of the employee's name, and keep a separate, confidential list of case numbers and names:
Reference: 29 CFR 1904.29(a) · 29 CFR 1904.29(b)(2) · 29 CFR 1904.29(b)(3) · 29 CFR 1904.29(b)(6) · 29 CFR 1904.29(b)(7) · 29 CFR 1904.31(a)
Work is restricted when, because of the injury or illness, you keep the employee from one or more routine functions of their job or from working the full workday, or a physician or other licensed health care professional recommends that. Routine functions are work activities the employee regularly performs at least once per week.
You do not have to record a restriction or transfer imposed only for the day of the injury.
Reference: 29 CFR 1904.7(b)(3)(i) · 29 CFR 1904.7(b)(3)(iv) · 29 CFR 1904.7(b)(3)(vii) · 29 CFR 1904.7(b)(4)(i) · 29 CFR 1904.7(b)(4)(ii) · 29 CFR 1904.7(b)(4)(iii)
Save the 300 Log, the privacy case list, the annual summary and the 301 forms for 5 years following the end of the calendar year they cover.
Reference: 29 CFR 1904.32(a) · 29 CFR 1904.32(b)(2)(i) · 29 CFR 1904.32(b)(3) · 29 CFR 1904.32(b)(6) · 29 CFR 1904.33(a) · 29 CFR 1904.35(b)(1)(i) · 29 CFR 1904.35(b)(1)(iv) · 29 CFR 1904.35(b)(2)(iii)

Take the courseFact-checked against the regulation text on October 09, 2026. This certificate records completion of awareness training based on OSHA 29 CFR Part 1904. It is not an OSHA card or license. Part 1904 does not set a training or certification requirement for recordkeepers. Your employer remains responsible for its injury and illness records and must inform each employee of its procedure for reporting work-related injuries and illnesses.
This guide explains the rule in plain words. Always read the regulation itself and your employer's site-specific procedures.
