Overhead and Underground Safety Practices

Dig Safely

In Pennsylvania, wait at least two full business days, excluding the date you notify 811, weekends and holidays.

Always contact your state 811 center before digging and for the most current requirements.
Distance Is Your Best Protection
Keep yourself, your tools and all equipment at least 10 feet away from overhead power lines carrying 50 kV or less. Higher-voltage lines require greater working distances. Contact Duquesne Light at 412-393-7100 to confirm power line voltages and distance requirements for your job site.
