TRIR Calculator
Calculate Total Recordable Incident Rate for workplace safety assessment
Calculate TRIR
Total hours worked by all employees in the past year
OSHA recordable injuries and illnesses
Quick Fill Example
Try this example: 2 million hours worked with 2 recordable injuries:
Get Started
Enter the total hours worked by all employees and the number of recordable injuries to calculate your TRIR score. Use the example data button to see how it works.
TRIR Calculation Formula
Where:
- 200,000 represents the equivalent of 100 employees working 40 hours per week, 50 weeks per year
- Recordable Injuries include all OSHA-defined workplace injuries and illnesses
- Hours Worked is the total hours worked by all employees during the reporting period
Example: If 2 injuries occurred during 2,000,000 hours worked:
TRIR = (2 × 200,000) ÷ 2,000,000 = 0.2
TRIR Risk Levels
Low Risk
TRIR < 3.0
Excellent safety performance
Moderate Risk
TRIR 3.0 - 8.0
Acceptable, room for improvement
High Risk
TRIR > 8.0
Requires immediate attention
Recordable Incidents
Medical treatment beyond first aid
Days away from work
Restricted work or job transfer
Loss of consciousness
Significant injury diagnosed by medical professional
Death (report within 8 hours)
OSHA Compliance Tips
Keep accurate records of all workplace incidents
Implement comprehensive safety training programs
Conduct regular workplace safety inspections
Report fatalities to OSHA within 8 hours
Compare your TRIR with industry benchmarks
Understanding TRIR (Total Recordable Incident Rate)
What is TRIR?
TRIR (Total Recordable Incident Rate), also known as TRIF (Total Recordable Incident Frequency), measures the number of work-related injuries and illnesses per 100 full-time workers during a one-year period. It's a key safety metric used by OSHA to assess workplace safety performance.
Why is TRIR Important?
- •OSHA uses TRIR to compare companies' safety performance
- •High TRIR may trigger OSHA inspections
- •Helps identify areas for safety improvement
- •Benchmark against industry standards
Recordable Incidents Include
Medical Treatment Beyond First Aid
Any treatment that goes beyond basic first aid, including sutures, prescription medications, or treatment by a medical professional.
Work Restrictions
Cases where employees cannot perform their regular duties or are transferred to other jobs due to work-related injuries or illnesses.
Days Away from Work
Any time an employee misses work beyond the day of injury due to a work-related incident.
TRIR Calculation Steps
Count total hours worked by all employees in the past 12 months
Count all recordable injuries and illnesses per OSHA criteria
Apply the formula: (Injuries × 200,000) ÷ Hours Worked
Compare result to industry benchmarks and risk levels
Improving Your TRIR
Implement comprehensive safety training programs
Conduct regular workplace hazard assessments
Establish clear safety protocols and procedures
Provide proper personal protective equipment (PPE)
Foster a culture of safety awareness and reporting
Important Considerations
- ⚠TRIR reflects past performance and does not predict future incidents
- ⚠Accurate record-keeping is essential for reliable TRIR calculations
- ⚠Compare your TRIR to industry-specific benchmarks for meaningful analysis
- ⚠High TRIR rates may result in OSHA inspections and legal consequences
