Importance of TRIR Calculation

  • TRIR gives you direct insight into your company’s past safety performance.  If your TRIR scores are poor, it may lead to an uptick in surprise OSHA inspections and penalties. In addition, OSHA may increase its oversight of your company’s EHS programs.
  • Your insurance company may use TRIR data to determine your premiums. The higher your recordable incident rate, the more you could be paying for insurance.
  • Prospective employees may investigate your company’s safety performance, including TRIR scores. A high TRIR could signal a company’s lack of focus on employee safety and become a potential barrier to talent sourcing.
  • Companies considering you as a vendor may be put off by a high TRIR score. They may see a business with a lower TRIR score as more favorable because it’s a testament to their safety record.

How to calculate TRIR:

TRIR is calculated by multiplying the number of recordable cases by 200,000 and then dividing that number by the number of manhours at the company.

For instance:

  • If the total recordable cases = 20
  • The number of hours worked (Manhour) = 100,000

TRIR calculation will follow thus:

(20 x 200,000)/100,000 = 40

A perfect TRIR score is zero, which means that there are no OSHA recordable incidents and a good TRIR is 3.0 or lower. High TRIR shows poor safety performance; it is important to keep your organization’s TRIR as low as possible.
