PPE Requirements for Working on or Near Energized Electrical Circuits
Note:
- Electrical equipment and circuit wiring are considered energized unless placed in an electrically safe work condition such as locked, tagged, tried, tested and grounded.
- Standard PPE (i.e. Hard Hat, FRC, Safety Glasses and Safety Shoes) is required for all electrical work.
- PPE requirement (i.e. UV face shield) is based on the assumption that work is performed within the arc-flash boundary.
