Total Recordable Incident Rate (TRIR) is a measure of the rate of recordable workplace injuries, normalized per 100 workers per year.

The factor is derived by multiplying the number of recordable injuries in a calendar year by 200,000 (100 employees working 2000 hours per year) and dividing this value by the total man-hours actually worked in the year.

RECORDABLE CASES: Occupational death, nonfatal occupational illness, and those nonfatal occupational injuries which involve one or more of the following: loss of consciousness, restriction of work or motion, transfer to another job, or medical treatment (other than first aid).

Total Recordable Incident Rate (TRIR)

The U.S. Occupational Safety and Health Administration (OSHA) has developed standards for the calculation of the Total Recordable Incident Rate (TRIR) and the Lost Time Incident Rate (LTIR). These standards are used to report global statistics for the Newpark family of companies.
