What is Energized Work? • Any work on or near circuits or components energized at or above 50 volts, where direct contact is possible, is “energized work”. What energized tasks require an EWP? • Installing or removing energized components, making or breaking wiring connections What energized tasks no not require an EWP? • Taking measurements with electrical instruments • Troubleshooting tasks not requiring disassembly of energized electromechanical devices. 2
What about PPE? Proper PPE, to protect from the known hazards, must always be worn, with or without an Energized Work Permit. 3
Each site may develop their own Energized Work Permit form, but all should require the following information: 1. 2. 3. 4. 5. 6. 7. 8. 9. Define the task, equipment, circuit, location, and time. Establish the flash protection boundary and the approach limits. Confirm that PPE and insulated tools are available. Prohibit access to the work area by non-qualified persons. Identify all required tools and safety precautions. Insure good communication is available. Identify the individuals who will do the work. Require a JSA or risk analysis review with the workers. Identify the proper safety disconnect for the equipment. The sample Energized Work Permit (EWP) on the next slide includes the features an EWP would need in N. A. All sites must comply with their local laws. 4
