TRIR Calculator [OSHA Total Recordable Incident Rate Calculator]
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 |
What is Total Incident Rate – Let’s Calculate The Total Recordable Incident Rate (TRIR) Of Your Company In 2025:
A TRIR Calculator is a tool used to calculate the Total Recordable Incident Rate (TRIR), a key safety metric that measures the number of recordable workplace incidents per 200,000 hours worked.
Basically, the TRIR is widely used by organizations to evaluate their safety performance and compliance with OSHA standards.
The calculator simplifies the process by factoring in the number of OSHA-recordable incidents, total hours worked, and the OSHA-standard multiplier of 200,000.
For example, businesses can use the TRIR calculation formula to monitor trends, assess monthly or rolling 12-month averages, or compare against industry benchmarks. Tools like the TRIR calculator online make this process accessible and efficient.
A good TRIR is often below the industry average, indicating strong safety practices. This metric is particularly valuable for identifying areas for improvement, understanding incident frequency, and ensuring compliance with regulations.
Additionally, calculators for related metrics like DART (Days Away, Restricted, or Transferred) or LTIR (Lost Time Injury Rate) provide a comprehensive view of workplace safety.
Final Words:
In conclusion, the TRIR Calculator is an essential resource for tracking workplace safety metrics. It empowers organizations to measure performance, maintain compliance, and foster a culture of safety and accountability.
