What is TRIR?

  • Definition of TRIR
  • Why TRIR Matters
  • Who Uses TRIR?
The Total Recordable Incident Rate (TRIR) is a key safety metric used to measure the number of OSHA recordable incidents per 100 full-time employees over a standard period, typically a year. It helps organizations assess and benchmark their workplace safety performance.
TRIR in Safety Management

TRIR in Practice

  • A company with 5 incidents and 200,000 hours worked has a TRIR of 5.0.
  • A lower TRIR indicates a safer workplace.

Step-by-Step Guide to Using the TRIR Calculator

  • Gathering Your Data
  • Entering the Numbers
  • Interpreting the Result
To use the TRIR calculator, collect the total number of recordable incidents and the total hours worked for your chosen period. Enter these values into the calculator to instantly receive your TRIR.
Quick and Accurate Calculation

Step-by-Step Examples

  • If you had 3 incidents and 120,000 hours worked, your TRIR is 5.0.
  • If you had 0 incidents, your TRIR is 0.0, indicating no recordable incidents.

Real-World Applications of TRIR

  • Benchmarking Safety Performance
  • Regulatory Compliance
  • Continuous Improvement
TRIR is widely used by safety professionals, HR departments, and management to benchmark safety performance, comply with OSHA regulations, and drive continuous improvement in workplace safety.
TRIR in Industry Reports

Industry Use Cases

  • Construction companies use TRIR to compare safety across projects.
  • Manufacturers track TRIR to meet regulatory requirements.

Common Misconceptions and Correct Methods

  • Misunderstanding the Formula
  • Incorrect Data Entry
  • Comparing Across Industries
A common mistake is to use the wrong multiplier or to include non-recordable incidents. Always use 200,000 as the multiplier and only include OSHA recordable incidents for accurate TRIR calculation.
Avoiding Calculation Errors

Misconceptions in Practice

  • Including minor first-aid cases inflates TRIR incorrectly.
  • Using 100,000 instead of 200,000 as the multiplier halves the TRIR value.

Mathematical Derivation and Examples

  • The TRIR Formula
  • Sample Calculations
  • Interpreting Results
The TRIR formula is: TRIR = (Total Recordable Incidents × 200,000) / Total Hours Worked. This standardizes the rate per 100 full-time employees, making it easy to compare across organizations and industries.
Worked Examples

Mathematical Examples

  • With 4 incidents and 180,000 hours: TRIR = (4 × 200,000) / 180,000 = 4.44.
  • With 2 incidents and 45,000 hours: TRIR = (2 × 200,000) / 45,000 = 8.89.
