Chasing The TRIR Presentation
By Kirk Dighton MS P

How does your company match up to the North American Industry Classification System (NAICS Code) in your class?  Contracting with some companies may require comparing your company’ Total Recordable Incident Rate (TRIR) and other injury data to like companies in the nation. If your numbers are higher than the “normal” NAICS Code, your company may not get the bid or you have to go through a tap dance to prove your company is “safe enough” to be worthy of doing the job for your customer. This presentation will explore methods of chasing the TRIR and creating a safe work environment for your employees where everyone wins. The employees go home at the end of the day safe and sound and the company wins more job bids with improved safety data.


At the end of this presentation, the attendee will be able to:

  1. Identify leadership traits that enhance incident prevention atmosphere on the worksite.
  2. Know how to bring the human aspect in to the environmental health and safety role to enhance the proactive safety climate and achieve desired results.
  3. Understand transformational and servant leadership styles that will enhance buy in of the safety culture you desire for your company.
  4. How to influence front line leadership to achieve improved safety performance and bring the data in line with NAICS.
