Why this matters
An arc flash can cause severe burns and injury even to people standing some distance away.
What to cover
- Only qualified people work on or near energized electrical equipment.
- De-energize and lock out whenever you can.
- Keep panel covers closed and barriers in place.
- Respect the approach boundaries on equipment labels.
- Wear the PPE the label or your procedure requires.
- Report damaged or missing labels.
Ask the crew
- Who here is qualified to work on this panel?
- Where are the labels?
- What would you do if a panel looked damaged?
One thing to do today
Walk the electrical rooms and check labels and barriers.
