Total Recordable Incident Rate (TRIR)
Number of all recordable workplace safety incidents per 200,000 hours worked (OSHA standard)
What is Total Recordable Incident Rate (TRIR)?
Total recordable incident rate is the number of recordable workplace injuries and illnesses for every 200,000 hours worked, roughly the hours of 100 full-time employees in a year. It shows how often people are hurt at work.
It is a widely used, standardised safety measure that lets organisations compare their performance.

- (Number of recordable incidents × 200,000) / Total hours worked
How to calculate it
Multiply the number of recordable incidents by 200,000, then divide by total hours worked.
For example, if there were 8 recordable incidents over 1,600,000 hours, the rate is (8 x 200,000) / 1,600,000 = 1.0.
Recordable incidents are those that meet the reporting criteria, such as medical treatment beyond first aid. Use the same definitions each time.
