Since January 1, 2015, federal rules have required employers to report to OSHA within 24 hours, by phone, in person, or online, every time a worker is hospitalized as an inpatient or loses a body part on the job. Two years of those calls — 2022 and 2023 — produced 19,690 reports of amputations and hospitalizations, about 27 every single day. It is the most direct data the country has on how workers get maimed rather than killed. It is also, by OSHA's own admission, roughly half the real picture. This analysis reads the severe-injury data for what it plainly shows — machines and falls dismember and hospitalize workers with grim regularity — and for the two structural blind spots that make even this sobering number an undercount. The result is a map of American workplace harm that the fatality statistics miss entirely.
At a glance (OSHA SIR, 2022–2023): 19,690 inpatient hospitalizations and amputations at federal-OSHA establishments — about 27 a day · the dataset covers only ~half of U.S. workers (State Plans excluded) · leading event: caught-in/compressed, 23% · leading source: machinery, 25% · 0 eye losses reported 2015–2023. Employers reported 19,690 amputations and inpatient hospitalizations to federal OSHA in 2022 and 2023, about 27 per day, but the dataset covers only about half of U.S. workers because State-Plan states are not included.
The injuries you have to phone in
Most workplace-injury data is passive — it is logged, tabulated, and released a year later. The Severe Injury Report is different: it is an affirmative duty to notify OSHA in real time. Under 29 CFR 1904.39, a work-related amputation, inpatient hospitalization, or eye loss must be reported within 24 hours, and a fatality within 8 (29 CFR 1904.39(a)(1)-(2)), by phone or in person to the nearest Area Office, by phone to 1-800-321-OSHA, or online (29 CFR 1904.39(a)(3)). Only events inside a window count: a death within 30 days of the incident, and a hospitalization, amputation, or eye loss within 24 hours of it (29 CFR 1904.39(b)(6)). An inpatient hospitalization means a formal admission to the in-patient service of a hospital or clinic for care or treatment (29 CFR 1904.39(b)(9)). The threshold is deliberately high — these are the injuries that change a life, not a paper cut — which is what makes the count meaningful.
OSHA severe injury reports, federal jurisdiction, 2022–2023
Source: OSHA, "2022 & 2023 Summary of Severe Injury Reports." The 27-per-day pace matches 2015 and sits below the 2018 peak of 31.
Twenty-seven a day is the number to sit with. Every working day, on average, twenty-seven American workers under federal OSHA alone are hurt badly enough to lose a limb or be admitted to a hospital — and that is before adding the State-Plan states the federal dataset leaves out.
How workers get maimed: the mechanism map
The value of the SIR data is its specificity. Because every report is coded by event and source, it draws a precise picture of the physical mechanisms behind severe injury — and the picture is dominated by two things: machines that catch and crush, and falls.
Leading events behind severe injuries (2022–2023)
Share of all reported amputations and hospitalizations
Leading sources: Machinery 4,548 (25%) · Structures & surfaces 3,908 (22%) · Vehicles 2,853 (16%)
Source: OSHA SIR 2022–2023. Machinery is the single largest source of severe injury.
Note how this differs from the fatality data. Where workplace deaths are led by transportation incidents and falls, workplace maimings are led by machinery — the caught-in, crushed, and amputated injuries of the industrial workplace. A worker is far more likely to survive a machine than a highway, so the machine dominates the injuries you live with. This is why machine guarding and lockout/tagout, unglamorous as they are, sit at the center of severe-injury prevention.
The spotlights: where specific hazards concentrate
OSHA's report drills into four hazards, and each is a small data story in itself — a reminder that "severe injury" is not abstract but a forklift, a blade, a heatwave, or an assault.
Severe-injury spotlights, 2022–2023
Source: OSHA SIR 2022–2023. Each spotlight maps to a distinct control strategy.
Two of these connect directly to hazards without a finished federal standard. The 451 heat hospitalizations are the emergency-room echo of the heat rule still in OSHA's pipeline; the 325 violence reports are the nonfatal layer beneath the 470 workplace homicides that OSHA also has no standard for. The severe-injury data, in other words, is measuring the cost of the regulatory gaps in real time.
The blind spots: why 19,690 is a floor
Here is the part that reframes every number above. OSHA is unusually candid about what its severe-injury data does not capture, and there are two distinct gaps.
Two reasons the real number is higher
- 1. Coverage. The public federal dataset "covers approximately half of U.S. workers." The 22 State-Plan states administer their own programs, and their reports are not in it — so the national total is on the order of twice what the federal data shows.
- 2. Underreporting. On top of the coverage gap, OSHA warns that employer underreporting affects the counts, and that the data "should not be considered statistically representative." Not every reportable amputation or hospitalization actually gets phoned in.
Source: OSHA SIR 2022–2023 methodology and data-limitations sections.
Stack the two together and the reported 19,690 becomes a conservative floor: roughly double it for the missing State-Plan half, then acknowledge that even the covered half is undercounted by employers who never make the call. Part of the fix is already in the rules: employers must have a reasonable procedure for employees to report injuries and must not discharge or discriminate against anyone who reports one (29 CFR 1904.35(b)(1)(i), (iv)). The severe-injury program is one of OSHA's best data assets precisely because it is timely and specific — but reading it correctly means reading it as the visible portion of a larger, partly hidden total.
What the data means for an employer
For a safety leader, the SIR data is less a statistic than a checklist of what actually sends people to the hospital — and a reminder that reporting is itself a legal duty with teeth.
- Guard the machines and the edges. Caught-in, struck-by, and falls dominate the events; machinery dominates the sources. A job hazard analysis of machine tasks, guarding, and lockout/tagout addresses the largest share of severe-injury risk.
- Know the 24-hour clock. A reportable amputation or hospitalization must reach OSHA within 24 hours (29 CFR 1904.39(a)(2)). Missing that window is its own citation, on top of whatever caused the injury.
- Record it right. When an injury happens, document it on the OSHA 301 incident form and keep your reporting obligations straight — the same record that satisfies OSHA is the one that drives your own prevention. The case goes on the 300 Log and the 301 report within 7 calendar days (29 CFR 1904.29(b)(3)).

The rules behind the mechanisms
Each pattern in the data maps to a rule already in force:
| Hazard in the data | What the rule requires | Rule |
|---|---|---|
| Machinery, caught-in and crushed | Guarding that protects the operator and others in the machine area | 29 CFR 1910.212(a)(1) |
| Point of operation, including food-processing blades | The point of operation guarded wherever it exposes an employee to injury | 29 CFR 1910.212(a)(3)(ii) |
| Servicing and maintenance | An energy control program before servicing where unexpected startup could injure | 29 CFR 1910.147(c)(1) |
| Forklifts | Each operator competent, through completed training and evaluation | 29 CFR 1910.178(l)(1)(i) |
| Falls, general industry | Protection at an unprotected side or edge 4 feet or more above a lower level | 29 CFR 1910.28(b)(1)(i) |
| Falls, construction | Protection at an unprotected side or edge 6 feet or more above a lower level | 29 CFR 1926.501(b)(1) |
| Heat | Potable drinking water in all places of employment | 29 CFR 1910.141(b)(1)(i) |
| Workplace violence | No specific standard; the General Duty Clause | 29 U.S.C. 654(a)(1) |
Machines and falls: where the severe injuries come from
OSHA's severe-injury data is the rarest thing in workplace safety: a timely, specific, national count of serious harm, reported by employers within a day of it happening. Read straight, it says machines and falls maim about 27 federally covered workers a day, with forklifts, food-processing blades, heat, and violence recurring in the narratives. Read honestly — with the coverage gap and underreporting OSHA itself flags — it says the true national number is roughly double the 19,690 on the page. Either way, it points to the same short list of controls. The employers who treat the SIR data as a prevention map, rather than a compliance afterthought, are working from the clearest evidence available of how their people actually get hurt.

Reporting duty per 29 CFR 1904.39 (effective January 1, 2015): amputations, inpatient hospitalizations, and eye losses within 24 hours, fatalities within 8. OSHA triages reports to an on-site inspection or a Rapid Response Investigation. OSHA notes underreporting and states the data "should not be considered statistically representative." No eye losses were reported 2015–2023. Not legal advice.
Frequently Asked Questions
What is OSHA's severe injury reporting requirement?
Under 29 CFR 1904.39, since January 1, 2015, every employer covered by the OSH Act must report to OSHA any work-related inpatient hospitalization, amputation, or loss of an eye within 24 hours — and any work-related fatality within 8 hours. This is separate from the injury log employers keep on site; it is an affirmative report OSHA requires the moment a severe injury happens, by phone or in person to the nearest Area Office, by phone to 1-800-321-OSHA, or online (29 CFR 1904.39(a)(3)), so the agency can decide whether to investigate.
How many severe injuries are reported to OSHA each year?
Establishments under federal OSHA reported 19,690 inpatient hospitalizations and amputations across 2022 and 2023 combined — an average of about 27 a day. That pace is consistent with the program's first year (2015) and below its 2018 peak of 31 per day. Crucially, this counts only workplaces under federal jurisdiction; the 22 states with their own OSHA plans are not in the public federal dataset, so the national total is substantially higher. Each of those reports is required within 24 hours under 29 CFR 1904.39(a)(2).
What are the most common causes of severe injuries?
In OSHA's 2022–2023 data, the leading events were being caught in or compressed by equipment or objects (4,158 reports, 23%), falls to a lower level (3,110, 17%), and being struck by an object or equipment (3,046, 17%). By source, machinery was number one (4,548, 25%), followed by structures and surfaces (3,908, 22%) and vehicles (2,853, 16%). The pattern is clear: machines and heights are where American workers lose limbs and land in hospitals. Those are the mechanisms OSHA's machine-guarding and lockout/tagout rules target (29 CFR 1910.212(a)(1); 29 CFR 1910.147(c)(1)).
Does OSHA's severe injury data capture every severe injury in the US?
No, and OSHA says so plainly. The public federal dataset 'covers approximately half of U.S. workers,' because the 22 State-Plan states run their own programs and their reports are not included. On top of that coverage gap, OSHA warns that employer underreporting further affects the numbers, so the data 'should not be considered statistically representative.' The reported figure is best read as a floor: the real national count of severe work injuries is meaningfully larger. Underreporting is itself a violation: every covered employer must report within the deadlines of 29 CFR 1904.39(a).
What happens after an employer reports a severe injury to OSHA?
OSHA triages each report. Depending on the injury and circumstances, the agency either opens an on-site inspection or asks the employer to conduct its own incident investigation and report back with proposed fixes — a process known as a Rapid Response Investigation (RRI), which usually involves no on-site visit. Reports fall into categories that steer them toward inspection or RRI. Either way, the event is entered into OSHA's information system, giving the agency a real-time signal of where serious harm is occurring. The report itself must give the establishment name, the location and time of the incident, the type of event, the number and names of the employees affected, a contact person, and a brief description (29 CFR 1904.39(b)(2)).
Which industries and hazards generate the most severe injury reports?
Construction and manufacturing report the highest numbers — together more than half of all reports — while the mining, quarrying, and oil-and-gas sector has the highest rate per 100,000 workers. OSHA's spotlights show where specific hazards concentrate: 1,190 forklift-related reports, 440 involving food-processing machinery (75% of them a finger amputation), 451 heat-related hospitalizations, and 325 involving workplace violence in 2022–2023 alone. Forklift operators must be trained and evaluated before they operate a truck (29 CFR 1910.178(l)(1)(i)-(ii)).
