High-energy control assessment
A field assessment of whether each high-energy hazard on a task has a Direct Control.
Observe one crew doing one task on one day. List every high-energy hazard. Each one either has a Direct Control or does not:
- Success
- The hazard has a Direct Control.
- Exposure
- It does not.
The score is successes divided by successes plus exposures. It measures the controls on live work before anything happens, which is why it sits alongside the Safety Classification and Learning model used after an event. In Hallowell’s research, even at industry-leading companies only 65 to 75% of high-energy hazards had a Direct Control. The published method and rulebook carry a name trademarked by the Colorado Construction Safety Laboratory; GeneXR teaches the method and does not use the mark.
