Fainting at work is OSHA recordable when two things are true: the episode is work-related, and the employee actually lost consciousness. Loss of consciousness is one of the automatic recording triggers in 29 CFR 1904.7, and it applies no matter how briefly the worker was out. The harder call is usually work-relatedness, because if the faint came purely from a personal medical condition with no workplace contribution, the case stays off the log.1Occupational Safety and Health Administration. 29 CFR 1904.7 – General Recording Criteria
Loss of Consciousness Is a Standalone Trigger
OSHA’s general recording criteria list several outcomes that make a work-related case recordable on their own: death, days away from work, restricted duty or job transfer, medical treatment beyond first aid, loss of consciousness, and a significant diagnosis by a licensed healthcare professional. Loss of consciousness stands by itself. If a worker blacks out because of something work-related, the case belongs on the OSHA 300 Log even if the worker felt fine two minutes later and needed no treatment.1Occupational Safety and Health Administration. 29 CFR 1904.7 – General Recording Criteria
OSHA reinforced this in a 2015 interpretation letter. An employee cut his finger on a vinyl saw clamp and then fainted after seeing his own blood while a coworker put on a bandage. The cut only needed a Band-Aid, but the fainting made the case recordable, because the work-related laceration contributed to the loss of consciousness.2Occupational Safety and Health Administration. Determining Whether an Injury or Illness Is Work-Related
The injury didn’t have to be serious. The treatment didn’t have to be extended. Once consciousness was lost through a chain that started at work, the recording obligation attached.
When Fainting Counts as Work-Related
OSHA presumes an injury or illness is work-related whenever it results from an event or exposure in the work environment. Employers don’t have to prove a causal link; the connection is assumed unless a regulatory exception applies.3Occupational Safety and Health Administration. 29 CFR 1904.5 – Determination of Work-Relatedness
Typical work causes of fainting include heat stress, chemical exposure, overexertion, dehydration from physical work, and inhaling fumes or gases. The workplace event doesn’t have to be the only cause. If a worker has an underlying heart condition and something at work tips that condition into a fainting episode, the case is work-related, because the standard is whether the work event was “a discernible cause,” not the sole cause.2Occupational Safety and Health Administration. Determining Whether an Injury or Illness Is Work-Related
Significant aggravation of a pre-existing condition counts too. If the condition would not likely have caused a loss of consciousness on its own, but a workplace event or exposure pushed it over the edge, that aggravation makes the case recordable.3Occupational Safety and Health Administration. 29 CFR 1904.5 – Determination of Work-Relatedness
When Fainting at Work Is Not Recordable
Several regulatory exceptions can break the presumption of work-relatedness, even when the faint happens on the clock and on site.
Purely Personal Medical Conditions
If the fainting results solely from a personal health condition with no workplace contribution, it falls outside the recording requirement. OSHA names epilepsy, diabetes, and narcolepsy as examples of conditions that can cause fainting unrelated to work. The word “solely” is doing the work in that rule. Any workplace event or exposure that contributed to the episode, or that significantly aggravated the underlying condition, defeats the exception.4eCFR. 29 CFR Part 1904 – Recording and Reporting Occupational Injuries and Illnesses
Voluntary Wellness and Recreational Activities
Fainting during a voluntary workplace blood drive, flu shot clinic, or recreational fitness event is not recordable, as long as participation was voluntary. The exception covers wellness programs, medical screenings, exercise classes, and similar activities.4eCFR. 29 CFR Part 1904 – Recording and Reporting Occupational Injuries and Illnesses
Personal Food or Drink
If an employee faints because of something they brought from home or bought on site for personal consumption, the incident is not work-related. That exception disappears if the food was contaminated by a workplace substance like lead, or if the employer supplied it and it caused the illness.4eCFR. 29 CFR Part 1904 – Recording and Reporting Occupational Injuries and Illnesses
Commuting Through a Company Parking Lot
An incident caused by a motor vehicle accident on a company parking lot or access road while the employee is commuting to or from work is not considered work-related, even though the lot is employer-controlled property.3Occupational Safety and Health Administration. 29 CFR 1904.5 – Determination of Work-Relatedness
Fainting Compared to Feeling Lightheaded
The regulation turns on the worker actually becoming unconscious. Feeling dizzy, lightheaded, or on the verge of passing out does not by itself meet the loss-of-consciousness criterion. OSHA’s language requires that the worker “become unconscious.”1Occupational Safety and Health Administration. 29 CFR 1904.7 – General Recording Criteria
That doesn’t automatically clear a near-faint from the log. If a dizzy worker falls and breaks a wrist, the fracture requires medical treatment beyond first aid, which is its own recording trigger. And a physician’s evaluation may produce a significant diagnosis that pulls the case back in. So a near-miss can still be recordable through a different door.
How to Record the Case
Once you’ve concluded the fainting incident is work-related and recordable, you have seven calendar days from learning about it to get it onto the forms.5Occupational Safety and Health Administration. 29 CFR 1904.29 – Forms
Three forms are involved:
- Form 300, the running log. Each recordable fainting incident gets its own line, and you check the “loss of consciousness” column.
- Form 301, the incident report. This captures what happened, how, and the outcome for the individual case.
- Form 300A, the annual summary posted in the workplace at year end.
If the worker also missed days, was placed on restricted duty, or received medical treatment beyond first aid, check those columns too. Secondary injuries from the fall, such as a head laceration or a broken bone, are recorded as part of the same case rather than as a second entry.1Occupational Safety and Health Administration. 29 CFR 1904.7 – General Recording Criteria
Faster Reporting If the Outcome Is Severe
Most fainting cases won’t trigger OSHA’s rapid-reporting rules, but some will. A fainting episode that leads to a fatality must be reported to OSHA within eight hours. One that results in an inpatient hospitalization must be reported within 24 hours. Reports can go to the nearest OSHA area office, the toll-free line at 1-800-321-6742, or OSHA’s website. If the employer doesn’t learn about the severity right away, the clock starts when they find out.6Occupational Safety and Health Administration. 29 CFR 1904.39 – Reporting Fatalities, Hospitalizations, Amputations, and Losses of an Eye
Employers Who Don’t Have to Keep the Log
Not every employer has to maintain routine injury and illness records. Two partial exemptions apply. Employers with ten or fewer employees at all times during the previous calendar year are exempt, measured across the whole company rather than by location. Employers in certain low-hazard industries, including most office-based businesses such as legal services, accounting, insurance, and real estate, are also partially exempt regardless of size.
Neither exemption lifts the severe-outcome reporting rule. Even exempt employers must report any work-related fatality, inpatient hospitalization, amputation, or loss of an eye within the required timeframes. OSHA or the Bureau of Labor Statistics can also require an otherwise-exempt employer to keep records by asking in writing.
Penalties for Not Recording a Qualifying Case
Employers who fail to record a qualifying fainting incident face OSHA citations and civil penalties. Recordkeeping violations are generally other-than-serious, but OSHA can escalate to willful or repeated classifications when the failure looks intentional or fits a pattern.
Effective January 15, 2025, OSHA’s maximum penalties are up to $16,550 per serious or other-than-serious violation and up to $165,514 per willful or repeated violation. The figures are adjusted annually for inflation. Each unrecorded case can be treated as a separate violation, so systematic failure to log fainting incidents can stack quickly.7Occupational Safety and Health Administration. OSHA Penalties
Bad records also blind an employer to patterns. If several employees are fainting in the same area or on the same task, an incomplete log lets the underlying hazard sit unaddressed until someone gets seriously hurt.
