PPE Requirements for Working on or Near Energized Electrical Circuits  

Note: 

1. Electrical equipment and circuit wiring are considered energized unless placed in an electrically safe work condition such as locked, tagged, tried, tested and grounded.
2. Standard PPE (i.e. Hard Hat, FRC, Safety Glasses and Safety Shoes) is required for all electrical work.
3. PPE requirement (i.e. UV face shield) is based on the assumption that work is performed within the arc-flash boundary.
4. Voltage rated gloves with leather protectors are required for all energized work / voltage testing.
