Safety Performance

Total Recordable Incident Rate (TRIR)
0.00

A lower TRIR indicates a better safety record. This rate can be compared to your industry's average to benchmark performance.


Track your workplace safety at a glance. Our TRIR Calculator computes the Total Recordable Incident Rate using your number of recordable incidents and total hours worked. The result helps safety managers, HR teams, and EHS professionals benchmark performance and spot trends.

What is TRIR?

TRIR stands for Total Recordable Incident Rate. It expresses the number of OSHA-recordable incidents per 200,000 hours worked. Using TRIR makes it easy to compare safety performance across sites or companies of different sizes.

Standard formula

TRIR = (Number of Recordable Incidents × 200,000) ÷ Total Hours Worked

Why use this TRIR Calculator?

  • Easy benchmarking: Compare your rate to industry averages even if your workforce size differs.
  • Quick insights: Get a clear number you can track month to month and year to year.
  • Supports decisions: Use TRIR to guide training, staffing, and safety investments.
  • Free and fast: No manual math — enter two values and get the TRIR instantly.

How to use the calculator

  1. Enter the Number of Recordable Incidents for the period (e.g., 5).
  2. Enter the Total Hours Worked by All Employees in the same period (e.g., 1,250,000).
  3. The calculator returns the TRIR value and a short interpretation.

Example (based on your inputs)

Inputs provided:

  • Number of Recordable Incidents = 5
  • Total Hours Worked = 1,250,000

Step-by-step calculation:

  1. Multiply incidents by 200,000: 5 × 200,000 = 1,000,000.
  2. Divide by total hours worked: 1,000,000 ÷ 1,250,000 = 0.80.

Result: Total Recordable Incident Rate (TRIR) = 0.80

How to read the result

  • Lower is better: A lower TRIR means fewer recordable incidents relative to hours worked.
  • Benchmark: Compare 0.80 with your industry average. Many industries consider TRIR below 1.0 a strong record, but acceptable ranges vary by sector.
  • Trend watching: Track TRIR over time. A rising TRIR is an early warning to review procedures, training, or resources.

Who should use this tool?

  • Safety managers and EHS professionals
  • HR and operations leaders
  • Site supervisors and plant managers
  • Consultants preparing safety reports or bids

Tips to lower TRIR

  • Run regular safety training and toolbox talks.
  • Investigate all incidents and share lessons learned.
  • Improve near-miss reporting — fix hazards before they cause injuries.
  • Maintain staffing and fatigue management to reduce human error.

Frequently Asked Questions (FAQ)

What counts as a recordable incident?

A recordable incident typically includes work-related injuries or illnesses that require medical treatment beyond first aid, days away from work, restricted duty, or loss of consciousness. Follow your local regulatory guidance (for example OSHA in the U.S.) for exact definitions.

Why use 200,000 hours in the formula?

The 200,000-hour base represents 100 employees working 40 hours per week for 50 weeks a year. It standardizes TRIR so organizations of different sizes can be compared fairly.

How often should I calculate TRIR?

Calculate TRIR monthly or quarterly for operational visibility, and annually for benchmarking and reporting. Monthly checks help spot trends early; annual TRIR is useful for external comparisons.

Can TRIR be used across industries?

Yes, TRIR is widely used across industries, but acceptable targets differ. Always compare with relevant industry peers rather than a generic number.
