OSHA TRIR Calculator
Use this free TRIR calculator to find your OSHA Total Recordable Incident Rate and understand how your safety performance compares over time.
TRIR is a standard OSHA metric used to track safety performance in the United States. It’s commonly requested by general contractors and owners, insurance providers, prequalification systems (ISNetworld, Avetta, PICS), and internal safety and leadership teams.
TRIR is calculated using the formula below:
TRIR = (Number of OSHA recordable incidents X 200,000) / (Total number of hours worked)
The TRIR calculation formula normalizes your incident count to 100 full-time workers (40 hours/week, 50 weeks/year = 200,000 hours). This lets you compare safety performance across companies of any size, from a 15-person crew to a 5,000-employee operation.

Count your OSHA recordable incidents
Include any work-related injury or illness that resulted in medical treatment beyond first aid, days away from work, restricted work or job transfer, loss of consciousness, or a significant diagnosis by a licensed healthcare professional. Do NOT include first-aid-only cases. (29 CFR 1904.7)
Total your hours worked
Add up all employee hours for the period, including supervised temporary workers. Exclude vacation, sick leave, holidays, and bereavement, even if paid. If you have salaried employees without tracked hours, estimate at 8 hours per workday or use scheduled hours.
Apply the formula
TRIR = (Recordable Incidents × 200,000) ÷ Total Hours Worked
Worked Example
Your crew of 45 workers logged 93,600 hours last year with 2 recordable incidents.
TRIR = (2 × 200,000) ÷ 93,600
= 4.27
That’s above the all-industries average of 2.3 (BLS, 2024). See the benchmarks below to compare against your specific industry.
TRIR Industry Benchmarks (2024 BLS Data)
Your TRIR only means something when you compare it to your industry. Here are the most relevant sectors, based on the 2024 Survey of Occupational Injuries and Illnesses (published January 2026):
| Industry | NAICS | TRIR (2024) |
|---|---|---|
| All private industry | — | 2.3 |
| Construction | 23 | 2.4 |
| Specialty trade contractors | 238 | 2.6 |
| Oil & gas extraction | 211 | 0.5 |
| Mining (except oil & gas) | 212 | 2.0 |
| Manufacturing | 31-33 | 2.5 |
Source: U.S. Bureau of Labor Statistics, SOII 2024. Rates per 100 full-time equivalent workers.
A TRIR below your industry average is generally considered good. But “good” is relative. A construction company with a 2.0 is outperforming most of the sector, while an oil & gas company with the same rate is significantly above their peers.
Now that you have your TRIR… here’s what it means
You’re here because someone is asking for it: prequal, insurance, or a bigger bid.
TRIR is the number they see, but what they judge is whether your safety proof and field habits would hold up if they asked for it tomorrow.
A TRIR below your industry average opens doors. A TRIR above it means more questions at prequal, tighter scrutiny on your OSHA 300 log, and a harder time winning bids. Either way, the number is just the starting point.

⚠️ Regulatory Update
Under OSHA’s expanded electronic recordkeeping rule (29 CFR 1904.41), establishments with 100+ employees in designated high-hazard industries must now submit Form 300, 300A, and 301 data annually via the Injury Tracking Application. The submission deadline is March 2 each year.
This data becomes publicly accessible, which means your TRIR is no longer just an internal number — GCs, insurers, and competitors can look it up. If your TRIR isn’t where you want it, the time to tighten up your safety program is before the next filing cycle.
Common Questions After Calculating TRIR
What is OSHA TRIR?
TRIR (Total Recordable Incident Rate) measures how often recordable work-related injuries and illnesses occur per 100 full-time workers per year. OSHA defines it under 29 CFR Part 1904. The formula is: (Number of OSHA Recordable Incidents x 200,000) / Total Hours Worked. The 200,000 represents 100 employees working 40 hours/week for 50 weeks. TRIR is the broadest incident rate metric and is always equal to or higher than your DART rate.
Is my TRIR “good”?
It depends on your industry. The 2024 all-industries average for private sector employers was 2.3 per 100 workers (BLS, January 2026). Construction runs around 2.4. Oil and gas extraction is much lower, around 0.5. A TRIR below your industry’s BLS average is generally considered good. But for prequalification (ISNetworld, Avetta, PICS), many clients set their own thresholds, often requiring your rolling 3-year TRIR to be below a specific number — sometimes as low as 1.0 for oil & gas work.
If my TRIR is low, do I still need to worry?
Yes. A low TRIR means fewer recordable incidents, but it doesn’t measure near misses, unsafe conditions, or the severity of incidents you did have. A company with a TRIR of 0.5 could still have one catastrophic near-miss that was inches from a fatality. TRIR is a lagging indicator — it tells you what happened, not what’s about to happen. Pair it with leading indicators like inspection completion rates, training currency, and near-miss reporting volume.
What if I don’t have everything organized?
Start with what you have. Pull your OSHA 300 log for recordable incidents and your payroll records for hours worked. If you don’t track hours precisely for salaried workers, OSHA allows you to estimate at 8 hours per workday or use scheduled hours (OSHA FAQ). The calculation itself takes 30 seconds. The harder question is whether you can produce the backup documentation — incident reports, training records, inspection logs — if a GC or insurer asks to see it.
What counts as an OSHA recordable incident?
A work-related injury or illness is recordable if it results in: death, days away from work, restricted work or job transfer, medical treatment beyond first aid, loss of consciousness, or a significant diagnosis by a licensed healthcare professional (29 CFR 1904.7). First-aid-only cases are NOT recordable. First aid includes wound cleaning, bandages, OTC medication at nonprescription strength, hot/cold therapy, and tetanus shots. If the treatment goes beyond that list, it’s recordable.
Why does the TRIR formula use 200,000?
The 200,000 normalizes your rate to a standard workforce of 100 full-time employees working 40 hours/week for 50 weeks (100 x 40 x 50 = 200,000). This lets you compare a 20-person crew to a 2,000-person operation on the same scale. Without it, larger companies would always have more raw incidents simply because they have more workers.
Do I include temporary workers in my TRIR calculation?
If your company supervises temporary workers on a day-to-day basis (directing the details, means, and methods of their work), then yes — include both their recordable incidents AND their hours worked in your calculation (OSHA FAQ 31-1). If the temp agency directs their daily work, the agency records the incident, not you.
If OSHA showed up, could you pull training, inspections, and closeouts in minutes?
