Narrative
On october 21st, 2020, crawfordsville fire department dispatch reported a structure fire that was gas fed with possible explosion. Vectren emergency responder arrived on site to a structure partially down and on fire. It appeared a concrete block wall had fallen on the gas meter set causing natural gas to feed the fire. Vectren emergency responders dug up and disconnected the gas service, stopping the flow of natural gas to the fire. No personal injuries were reported. It is inconclusive as to whether the explosion occurred as a result of natural gas migrating from outside the structure, due to inability to rule out other potential sources. The gas service line to this structure was pressure tested and determined to be not leaking. However, further investigations discovered concentrations of natural gas in the parking lot and near the foundation of this structure. The source of these underground gas readings was determined to be a crack on the bottom of the 6' aldyl-a gas main in old oak lane adjacent to this property. This crack appears to be consistent with an impingement failure. This damaged section of pipe was removed and replaced that same day.
