Millersburg Fire Company #1 units were dispatched this afternoon at 1353 hours to Isle of Q Road for a reported brush fire caused by downed power lines. Chief 20, Attack 20, Engine 201 and Tanker 20 responded. Upon arrival a power line was observed to be down arcing and sparking and set nearby natural cover on fire. Crews set up a safety perimeter around the power line, contained the fire and stopped it from spreading further and notified PP&L. Crews could not totally extinguish the fire due to the energized power line (7200 volts). Once PP&L arrived and secured power crews extinguished the remainder of the fire. A total of 22 volunteers responded to this call.
