Total Recordable Incident Rate Calculator

The Total Recordable Incident Rate (TRIR) Calculator helps you measure workplace safety by calculating your TRIR.
The total number of OSHA recordable incidents, such as work-related injuries or illnesses requiring medical attention beyond first aid. Example: If your workplace recorded 10 incidents in the past year, enter “10.”
The total number of hours worked by all employees over a specific time period (e.g., monthly, quarterly, annually). For a team of 50 employees working 40 hours a week for 50 weeks, the total would be 100,000 hours.
The 200,000 hours represent the total hours 100 employees work in a year (40 hours/week for 50 weeks), as defined by OSHA.
