What is TRIR?

TRIR, or Total Recordable Incident Rate, is OSHA’s standard metric for measuring workplace safety performance. It normalizes incident frequency against hours worked, so organizations of different sizes can compare performance on equal footing. The formula uses a base of 200,000 hours. That’s the equivalent of 100 full-time employees working 40 hours a week for 50 weeks a year.

The TRIR formula (OSHA incident rate formula)

(Recordable Incidents × 200,000) ÷ Total Hours Worked

TRIR calculation follows a three-step process:

  1. Count every OSHA recordable incident that occurred during the measurement period (typically the past 12 months).
  2. Total the hours worked by all employees — full-time, part-time, seasonal, and temporary — during the same period.
  3. Apply the TRIR formula: multiply your recordable incident count by 200,000, then divide by total hours worked.

The 200,000-hour constant normalizes your result to a rate per 100 full-time workers, making your OSHA incident rate comparable across organizations of different sizes and industries.

A recordable incident is any work-related injury or illness that results in:

  • Death
  • Loss of consciousness
  • Days away from work
  • Restricted duty or job transfer
  • Medical treatment beyond first aid

Injuries and illnesses that require only first aid, including over-the-counter medication at nonprescription strength, are not recordable under OSHA standards.

Yes. TRIR (Total Recordable Incident Rate) and TCIR (Total Case Incident Rate) refer to the same metric. OSHA uses TCIR in its official publications; TRIR is the more common term in industry practice. Both are calculated using the same formula and produce the same result.

OSHA requires annual recordkeeping, but calculating TRIR quarterly gives you trend data throughout the year. It also provides a chance to course correct before your annual number is set. High-volume operations and organizations with active safety improvement programs benefit most from monthly tracking.

Why your TRIR matters beyond the safety program

TRIR started as a safety compliance metric. For most organizations today, it functions as a financial and operational one too. A high rate raises costs, limits opportunities, and draws scrutiny from regulators, carriers, and leadership alike.

Bureau of Labor Statistics (BLS) survey data drives OSHA’s Site-Specific Targeting (SST) program. Organizations with an OSHA recordable incident rate above their industry average are more likely to receive programmed inspections. A high rate signals elevated risk and invites regulatory attention.

Carriers factor your incident history into experience modification rates, which directly affect your workers’ compensation premiums. A sustained high TRIR raises your cost of risk across renewals. Organizations that reduce their recordable incident rates over time see that improvement reflected in their premiums.

Prequalification platforms like ISNetworld and Avetta weight TRIR heavily in contractor eligibility decisions. A rate above threshold can disqualify you from bids regardless of your operational capabilities or safety investments.

Safety is increasingly a line item at the leadership table. EHS leaders are asked to defend their TRIR alongside budget requests — and to demonstrate how their programs connect to financial outcomes. A high or worsening rate without a clear improvement plan is a difficult conversation to have twice.

TRIR benchmarks by industry

Industry context is essential when interpreting your TRIR. A 2.0 in construction reflects strong performance. A 2.0 in financial services warrants a closer look. The benchmarks below are drawn from Bureau of Labor Statistics (BLS) data and represent annual recordable incident rates per 100 full-time workers.

What the number tells you

A rate below 1.0 is strong performance across most industries. A rate trending downward over three or more years is a more meaningful signal than any single-year figure. Trend direction, and whether your rate is improving relative to industry peers, is what safety leaders need to be prepared to explain to leadership, insurers, and prequalification reviewers.

TRIR tells you what happened. Leading indicators tell you what’s coming.

The formula is backward-looking by design. Every incident counted in a TRIR calculation has already occurred, with nothing left to prevent. Safety leaders who use TRIR as their primary signal are working from historical data. A complete safety program needs forward-looking signals too, so your team can intervene before an incident becomes an OSHA recordable.

Leading indicators are proactive measures that correlate with fewer recordable incidents before they happen. Organizations that consistently improve their TRIR have built systems to capture and act on:

The organizations with the strongest TRIR trajectories have made it easy for workers to report, and built systems that ensure those reports get reviewed and acted on.

Incidents that almost occurred are the most reliable early signal that a recordable incident is likely without intervention. Organizations with strong near-miss reporting cultures catch risks that others miss.

Structured field evaluations identify hazards before they produce injuries. Completion rates and finding closure rates are trackable leading indicators in their own right.

Task-level risk assessments conducted before high-exposure work surface risks at the point of highest control.

Frontline worker submissions surface conditions that management may not observe directly. The volume and closure rate of these reports signals the health of your reporting culture.

Where EHS measurement is heading in 2026

A growing number of safety leaders are moving beyond lagging indicators entirely. Newer methodologies, including pSIF (potential Serious Injury and Fatality), STKY, the Capacity Model, EEI Safety, and ASTM E2920, share a common premise: they assess why incidents occur from a risk perspective and build organizational capacity to absorb failure without serious injury. These frameworks give safety programs a more complete picture of risk than a TRIR calculation can provide on its own.

These approaches shift the conversation from total recordable incident counts to actual exposure to serious harm. EHS leaders who want to speak that language, and have a platform that supports it, are looking at tools built for these methodologies. Origami Risk is already building them in. The TRIR calculator is a useful starting point. The organizations ahead of the curve are running more advanced frameworks alongside it.

How to lower your TRIR

Meaningful TRIR improvement follows the same pattern across industries. Organizations build proactive systems to identify risk before it becomes recordable, investigate incidents thoroughly enough to address root causes, and make it easy for workers to surface hazards before they produce injuries.

  1. Build a reporting culture

    Near-miss reporting rates correlate with lower recordable incident rates. When workers trust that reporting is safe and that hazards get addressed, the data that surfaces is the earliest warning available. Anonymous reporting channels and visible follow-through on submitted hazards drive participation.

  2. Conduct structured incident investigations

    Incidents investigated beyond their immediate cause reveal systemic risks. Root cause analysis frameworks (5 Whys, fishbone analysis, and similar methods) surface the conditions that contributed to an incident and are likely to produce another if left unaddressed.

  3. Implement proactive audit and inspection programs

    Regular field audits create a visible safety presence and document conditions before they produce incidents. Audit data tracked over time surfaces patterns that single-site or single-incident observations cannot.

  4. Track leading indicators alongside lagging ones

    Near-miss counts, audit completion rates, corrective action closure rates, and JSA completion rates give you a forward-looking view of safety performance. EHS leaders who present these metrics alongside TRIR give leadership a fuller picture and a defensible case for safety program investment.

  5. Centralize safety data across sites

    Multi-site organizations that manage data in spreadsheets or disconnected systems cannot spot cross-site trends. Centralizing incident, audit, and inspection data in a single system makes it possible to identify which sites, operations, or job types drive the most recordable incidents. It also helps allocate resources to where they will have the most impact.

TRIR and your total cost of risk

Safety performance and financial performance are connected. EHS leaders who can demonstrate that connection to leadership have a stronger case for the resources and investment their programs require.

The most direct financial connection runs through workers’ compensation. When incident rates are high, claim frequency rises. When claim frequency rises, experience modification rates rise, and insurance premiums follow. Organizations that sustain lower TRIR trajectories over time tend to see lower workers’ compensation costs and more favorable renewal terms.

The challenge for most EHS leaders is that safety data and insurance data live in separate systems. Claims are managed by risk management or finance. Incident data lives in the EHS platform. Without a way to connect them, calculating how much a recordable incident actually costs the organization is difficult. Thus, making the financial case for preventive investment is harder still.

TRIR connects to cost of risk in a specific and limited way: it tells you what past incidents have already cost. The organizations with the most leverage over their total cost of risk are measuring risk before it becomes a recordable, which means tracking the leading indicators and modern methodologies that predict incident likelihood, not just count its outcomes. Origami Risk gives EHS and risk management leaders both views in one platform.

Origami Risk integrates EHS incident management with a full risk management information system (RMIS) and claims system. EHS leaders using Origami Risk can see the relationship between safety program performance and total cost of risk in a single platform. Then leaders can use that data to communicate safety outcomes in the financial terms that resonate with CFOs and COOs.

Frequently asked questions

Multiply your number of OSHA recordable incidents by 200,000, then divide by the total hours worked by all employees during the same period. The formula: (Recordable Incidents × 200,000) ÷ Total Hours Worked. Use our calculator above to run the TRIR calculation automatically. Just enter your incident count and total hours worked.

The TRIR formula is: (Number of Recordable Incidents × 200,000) ÷ Total Hours Worked. The 200,000 constant represents the hours 100 full-time employees would work in a year (50 weeks × 40 hours × 100 employees). It normalizes your incident rate so organizations of different sizes can compare results on equal footing. This is the same incident rate formula OSHA uses in its official recordkeeping guidance.

“Good” is industry-specific. In high-risk industries like construction and manufacturing, a TRIR below 2.0 reflects strong performance. In lower-risk industries like finance or professional services, a TRIR above 0.5 may be worth examining. The most meaningful context is your own trend over time and how your rate compares to your industry average per current BLS data.

TRIR counts all recordable incidents. LTIR (Lost Time Incident Rate) counts only those that result in days away from work. DART (Days Away, Restricted, or Transferred) rate covers incidents that resulted in days away from work, restricted duty, or job transfer. TRIR is the broadest measure; DART and LTIR are subsets that capture more severe outcomes. All three use the same 200,000-hour base in their formulas.

OSHA requires annual recordkeeping using Form 300. Most safety programs benefit from calculating TRIR quarterly to track trends throughout the year. Organizations undergoing active safety improvement programs or managing high-exposure operations often calculate monthly.

A work-related injury or illness is recordable if it results in death, loss of consciousness, days away from work, restricted work or job transfer, or medical treatment beyond first aid. Incidents requiring only first aid are not recordable. These include over-the-counter medication at nonprescription strength, wound closure strips, non-prescription-strength eye patches, and similar treatments.

Your incident history factors into your Experience Modification Rate (EMR or e-mod), which carriers use to adjust workers’ compensation premiums. A high TRIR sustained over the experience period raises your e-mod above 1.0 and increases your premiums. Reducing recordable incidents over time lowers your e-mod and reduces your cost of risk. The connection is direct and measurable.
