To calculate the Total Recordable Incident Rate (TRIR), multiply the total number of OSHA-recordable incidents by 200,000, then divide by the total hours worked by employees.
The TRIR Calculator is a vital tool for measuring workplace safety. TRIR quantifies the number of OSHA-recordable incidents per 200,000 working hours, representing the equivalent of 100 employees working 40 hours per week for a year.
Formula
TRIR = (I ∗ 200,000) / HW
Variable | Description |
---|---|
I | Total OSHA-recordable incidents |
HW | Total hours worked by employees |
TRIR | Total Recordable Incident Rate |
Solved Calculations
Example 1: Calculating TRIR for a Small Company
Step | Value |
---|---|
Total OSHA Incidents (I) | 5 |
Total Hours Worked (HW) | 100,000 |
TRIR = (5 ∗ 200,000) / 100,000 | 10.0 |
Example 2: TRIR for a Large Organization
Step | Value |
---|---|
Total OSHA Incidents (I) | 12 |
Total Hours Worked (HW) | 500,000 |
TRIR = (12 ∗ 200,000) / 500,000 | 4.8 |
