Front-Line Safety Excellence

Discover how to identify hazards using the Energy Wheel, conduct excellent pre-job safety briefings, have critical conversations, and respond to change using Stop Work Authority.

Improve the Quality of Your Existing Safety Practices

by showing your team what "good" looks like

This series is not about adding new things to your safety program. Instead, its about doing our key safety activities better.

 This series helps align your front-line safety efforts with the concept of energy and critical controls. Based on years of research and collaboration with hundreds of industry partners, this series shows your team what "good" looks like.

 The content involves using the energy wheel to identify all hazards, considering energy magnitude to determine which hazards are life-threatening, holding excellent pre-job discussions to create a safe work plan, having critical conversations to ensure team readiness, and guiding when and hope to stop work when conditions change. 

Intended for front-line workers, supervisors and safety professionals

In just two hours, take advantage of decades of research and learn what industry leaders agree are the most effective front-line safety practices.

Apply the Energy Wheel to recognize more hazards

Plan and deliver a high-quality safety briefing

Engage in critical conversations to identify and address key warning signs

Evaluate a changed condition and how to execute Stop Work Authority


Dr. Hallowell's delivery of energy-based hazard recognition is creative, engaging, and interesting. I left the session understanding how to enhance hazard recognition and risk assessment at the front line.
Jenny Bailey Director of Safety and Health • Xcel Energy
The energy-based safety approach has been transformational for our business. You can tell when it’s working. You hear the conversation change in the workplace. The delivery of the material is second to none. Our team quickly understood the process and recognized the benefit. Few programs are operationalized to this extent.
Mike Court Sr. Vice President of Health, Safety, Environment, and Quality • Graham Construction
The energy-based approach is backed by science, yet the theory is so easy to understand. Once the initial training to leadership and field crews has been done, the change in conversations is immediately evident… from the front lines to the executive boardrooms. The delivery of the material is also engaging and generates overwhelmingly positive feedback from participants. After 30 years of being involved in the safety field, I believe the energy method will be a game-changer.”
