What is the Energy Wheel in the context of STKY?

• A. A tool to help identify hazards related to different types of energy
• B. A device to measure energy consumption
• C. A wheel used to schedule breaks
• D. A rotation schedule for crew

Answer: (A)

The Energy Wheel is a visual tool used to identify hazards that come from different energy types before and during a task. It helps you map out where energy could be released or cause harm—electric, mechanical, thermal, chemical, gravitational, stored energy, and others—and then determine the appropriate controls to keep workers safe. By thinking through each energy type, you can decide what needs to be de-energized, isolated, or contained, what PPE or barriers are required, and how to verify that all energy sources are secured before work begins.

This isn’t about measuring energy usage, so it wouldn’t tell you how much energy a system consumes. It’s also not a tool for scheduling breaks or managing crew rotations. Those purposes don’t relate to hazard identification and control, which is what the Energy Wheel is designed to support.
