Pepco Urges Residents to Stay Away from Downed Power Lines
Assume all Downed Lines Are Energized

As Pepco workers continue to restore power, the Company strongly urges residents to stay clear of downed power lines and report them immediately to Pepco. The emergency number to call is 202-872-3432.

A downed power line always is considered dangerous whether it appears energized or not. Contact can cause serious injury or even death. No one should touch any line or attempt to remove any object that may be tangled in it, including an animal. Instead, call Pepco`s emergency number immediately.

A power line should be considered energized at all times, even lines which have been on the ground for a period of time. A deactivated line can become re-energized during the restoration process.

Residents should assume that all downed lines are energized power lines and may not be telephone or internet wires, which look the same to the untrained eye.

Pepco already has reports of more than 2,500 downed lines in its service area, creating an extremely dangerous situation. The Company is working to address this serious problem as a top priority.
