The Total Recordable Incident Rate (TRIR) is a key OSHA metric used to gauge the safety performance of a company within a specific industry. It measures the number of work-related injuries and illnesses that require medical attention beyond first aid per 100 full-time workers during a one-year period. A lower TRIR indicates a safer workplace.

Understanding TRIR
The formula for calculating the Total Recordable Incident Rate (TRIR) is:
TRIR = (Number of Recordable Incidents * 200,000) / Total Hours Worked
The '200,000' in the formula represents the number of hours 100 full-time employees working 40 hours per week for 50 weeks a year would accumulate (100 employees * 40 hours/week * 50 weeks/year = 200,000 hours). This standardizes the rate across different company sizes, making it comparable to industry averages.
What are "Recordable Incidents"?
According to OSHA, a work-related injury or illness is considered "recordable" if it involves:
Death
Days away from work
Restricted work or transfer of a job
Medical treatment beyond first aid
Loss of consciousness
A significant injury or illness diagnosed by a physician or other licensed health care professional
Interpreting Your TRIR:
Compare your calculated TRIR to industry-specific benchmarks published by OSHA or industry associations. A rate higher than the industry average suggests areas for improvement in your safety programs. A rate lower than the average indicates a strong safety culture.
