Keep yourself and others away from any fallen power lines. You never know when they might be energized. Call PECO (Emergency: 1-800-841-4141) right away and report the location of the downed wires. If a line falls on your car, stay in your car. If you must get out of the car, jump clear, do not touch any part of your car and the ground at the same time and stay clear of the fallen line.
