The Total Recordable Incident Rate (TRIR) is the number of recordable incidents per 100,000 hours worked and it represents an organization’s overall incident rate. It is calculated by dividing the number of recordable injuries or illnesses by the total hours worked in a given time period (usually one year).

What is TRIR/TRIF?

The TRIR or TRIF (Total Recordable Incident Frequency) is a measure of the rate of time-loss injuries in a workplace. It tells you how many time-loss injuries happened per 100 full-time employees.

You can use this calculator to find out what your TRIR is and compare it with other companies in your industry or region.

How to calculate the TRIR?

The TRIR is a percentage that shows those involved with a recordable incident how much of the total worker’s compensation cost was attributable to their accident. The meaning of TRIR is the Total Recordable Injury Rate. It’s calculated by dividing total recordable injuries by the number of hours worked times the total wages paid out during that period.

The formula for calculating it is:

\text {TRIR} = \frac {\text {Number of recordable injuries} \times 200000}{\text {Hours worked}}

List of recordable incidents

The list includes:

  • Serious injury. This is an injury that requires hospitalization for at least 24 hours or outcomes in permanent loss of function.
  • Unintentional firearm discharge. Any unintentional discharge of a firearm that results in injury to the employee or damage to equipment or property. This includes when the firearm was dropped, mishandled, or fired by someone other than the employee who had possession of it at the time of discharge.
  • Vehicle crash. Any crash involving any government-owned vehicle while on duty with damage exceeding $1,000 (including personal vehicles). This does not include traffic accidents involving non-government vehicles being used as part of official duties (such as a police car involved in an accident).
  • Workplace violence: Any act of violence committed by an assailant against another person on company premises where both parties are employed by a single employer during regular business hours or affecting those employees during their commute home from work; this includes domestic violence and sexual assault but excludes acts arising out of labor disputes between management and union officials

How to avoid incidents/injuries

In order to avoid incidents/injuries while working out, be alert and aware of your surroundings. Make sure you are not tired or fatigued. Be well hydrated prior to a workout. Wear the right shoes for the activity, such as cross-trainers for running or sneakers for weightlifting. Wear appropriate clothing that allows you to move freely without feeling restricted (tight jeans and yoga pants may cause difficulty during certain exercises). Eat healthy foods and get plenty of sleep so that your body has enough time to recover from workouts—this will make it harder for injuries to occur!
