Your total recordable incident rate: how many recordable injuries and illnesses you had per 100 full-time workers in a year. General contractors ask for it in prequalification.

## How TRIR is calculated

Multiply the number of recordable cases on your OSHA 300 Log by 200,000, then divide by the total hours all employees worked in the year. 200,000 hours is 100 workers × 40 hours × 50 weeks, which puts every company on the same scale.

### What counts as a recordable case?

A work-related injury or illness that results in death, days away from work, restricted work or transfer, medical treatment beyond first aid, loss of consciousness, or a significant diagnosed injury such as a fracture (29 CFR 1904.7).
### What is a good TRIR?

Lower is better. Compare against the rate the Bureau of Labor Statistics publishes for your NAICS industry for the same year, and against what your general contractor requires.
### Which hours do I use?

Actual hours worked by all employees, including overtime. Do not include paid vacation, sick leave or holidays.
