Narrative
At 9:12 am on 12/11/21, wisconsin gas company was notified that a gas meter assembly was hit at 517 wisconsin street, waupaca, wi and that a fire/explosion had occurred. A company first responder was dispatched to the scene and upon arrival found that a tractor with a snow plow hit the gas meter assembly while removing snow, resulting in the gas release. The release of gas was stopped at 10:35 am by use of a service curb valve. No fatalities or personal injuries necessitating in-patient hospitalization occurred; however, it was determined that the gas release caused dwelling damages in excess of the 191.3 reporting threshold of $122,000. The investigation identified a severed pipe nipple at the inlet to the meter set regulator as the source of gas release after being hit during the snow plowing operation. Eight residents were evacuated from the dwelling immediately after the meter set was struck and the dwelling remains uninhabitable due to the damages.
