Energy-Based
Hazard Recognition
How it works

A series of laboratory experiments have revealed that - regardless of culture, experience, industry, or trade - human beings have the same tendency to focus on certain types of hazards while being blind to others until prompted. Energy-based hazard recognition involves using the Energy Wheel to guide pre-job safety meetings and scanning of dangerous work environments. The wheel is intended to be used to prompt the brain to consider some hazards that would otherwise go unnoticed. Based upon two years of full-time pilot testing by researchers at the University of Colorado and Virginia Tech, the energy method consistently improved hazard recognition by 20-30%.

What we offer

Online Education Modules

In this 3-hour course, participants will learn how to use the concept of energy to improve hazard recognition, assess potential injury severity, and evaluate the adequacy of controls. The education module includes activities, instruction, and assessment delivered by Dr. Matthew Hallowell, an award-winning teacher and researcher. 

 

The course is ideal for clients who would like their employees and contractors to be prepared to implement these new strategies. Those who successfully complete the course receive a certificate. 

A 30-minute short course on the energy wheel is also available. 

In-Person Keynote Presentation

Dr. Matthew Hallowell offers keynote presentations on this topic and has delivered to audiences ranging from 100 to over 2,000. His presentation includes a number of engaging audience activities and generates a vibrant discussion.

Speaker Bio

In-Person Workshops

Workshops on energy-based hazard recognition is offered for all levels. Typically, we recommend that an organization host a leadership introductory session to explore whether the energy method is something that the organization would like to pursue. Subsequently, field-level management can be trained across the organization and implementation plans can be established.

Research Evidence 

Laboratory Experiments

We have performed a series of laboratory experiments using a combination of eye-tracking technology (see video), functional near-infrared spectroscopy (fNIRS), and common construction images to determine how the brain functions when identifying specific types of hazards. The research has provided insight regarding why some hazards capture our attention and others do not.

Field Experiments

Our position is that "safety philosophy" is not sufficient in directing limited safety resources. Therefore, we tested the hypothesis that the energy method improves hazard recognition and communication. We conducted over 4,800 worker hours of observation on active construction sites and applied multiple baseline experimentation to test our hypothesis. The results showed a 20-30% improvement across all projects. In short, you don't need to pilot test, we have done it already and the results have withstood the rigors of peer-review.
