This practice identifies and describes the 10 high-impact injury reduction techniques that make a significant, positive difference in health, safety, and environmental (HSE) performance.


This practice includes the following major sections:

  • Pre-Project HSE
  • HSE Education and Orientation
  • New Employee Development
  • HSE Awareness Program
  • Recognition and Rewards
  • Incident Reporting and Investigation
  • Pre-Task Planning
  • Management in Action
  • Audit/Assessments
  • Use of Networking and Resources


This practice applies to work activities and employees under the management of Onyx.


Although they have been around for a while, the high impact incident reduction techniques continue to show results when used on jobsites. Onyx believes these techniques are the basis of a good HSE program, and every project will benefit from implementing them. This program of incident reduction techniques has helped Onyx raise the level of expectation for HSE performance and provided the tools for us to make it happen.

The Onyx HSE audit measures how effectively projects execute the Incident Elimination techniques. If projects are not adhering to this program, they will not perform well on their audits. Additionally, projects applying for awards (i.e. VPP awards) are audited against these techniques.


It all started with the Construction Industry Institute (CII), which is a group of owners (like Exxon, DuPont, and GM); contractors and universities that study and support industry to improve safety, quality, and cost for its members.

A CII task force studied the construction industry first in 1993 and then again in 1999, looking at companies with construction projects valued from $50 million to $600 million, to produce what they found to be the most effective techniques to reduce workplace injuries. They identified best practices used by companies that had achieved safety excellence. The first study found 5 high-impact Incidents Elimination techniques that seemed to make a difference in safety performance; in 2001, CII expanded these 5 to 9 best practices. CII compared the safety performance rates of companies that used these techniques with those that did not, with astounding results. Incident rates plummeted on projects using the techniques.

Onyx adopted the results of the CII study, using CII’s high-impact techniques as the basis of the Incident Elimination Program, added our own commitment and experience, and have deveIoped a list of 10 high-impact incident reduction/elimination techniques.
