What is TRIR?

TRIR stands for Total Recordable Incident Rate. Also known as Total Case Incident Rate, TRIR is a key metric for evaluating the organization’s safety performance from the past year. It is a lagging indicator created by OSHA and used additionally for comparing safety performances of organizations within a particular industry. With TRIR, the lower the number the better your safety performance is.

How is TRIR calculated?

The formula from OSHA is as follows:

(Number of Incidents x 200,000) / total number of hours worked in a year 

A TRIR guage with a green, yellow, orange, red scale. Green is listed as Excellent. Red is listed as Poor.

So, where does OSHA get these numbers from? The number used for incidents include any work-related injury or illness that results in death, loss of consciousness, days away from work, restricted work activity, or medical treatment beyond first aid. 200,000 is the benchmark OSHA established representing the total number of hours 100 employees would log in 50 weeks in a standard 40-hour work week.

By dividing the product of those numbers by the total number of hours worked in a year, those doing business with your company will have a standardized understanding of how your safety program compares to your industry or your competitors.

The Total Recordable Incident Rate is key to ensuring you are providing employees with a safe workplace free from recognized hazards. A poor TRIR score can lead to an increase in surprise OSHA inspections or even higher insurance premiums. According to the Bureau of Labor Statistics, the TCIR for private industry employers in 2017 was a rate of 2.8 cases per 100 employees. If your TRIR score is high, it is probably time to overhaul your safety program.
