## TRIR Formula

The following equation can be used to calculate the total recorded incident rate of your business.

TRIR = I * 200,000 / HW

- Where TRIR is the total recorded incident rate
- I is the total OSHA incidents recorded
- HW is the total hours worked

To calculate the total recorded incident rate (TRIR), multiply the number of incidents by 200,000, then divide by the total hours worked.

## TRIR Definition
