Narrative
Upon arrival a natural gas fire was found burning at the base of a municipal owned power pole on the right front corner of 831 arbor st ne and a natural gas fire approx. 2 blocks away on the right side of home at 776 arbor st ne. At the house, gas had ignited on the union for the filter right above the lock-wing service valve and set the home on fire. The fire department was able to turn the gas off at the lock-wing service valve, on the meter set, and extinguish the flames. At the power pole, after determining that there was no gas migrating underground, the decision was made to dig up the 2" steel main in remote holes on either side of the fire and squeeze the line off. It was determined that a squirrel shorted the overhead power facility to the ground on the power pole. The ground rod for the pole was within 6" of the 2" coated and wrapped steel gas main. The grounded current caused an arc burn hole in the pipe at the ground rod and at the house riser causing fires at both locations. Repairs to the main were made and service was restored to the customers impacted.
