Location
MN, SCOTT
Narrative
Lightning struck the ground and/or the home adjacent to the natural gas service line. Current from the lightning strike traveled through the entire tracer wire along the service line resulting in a below ground leak near the meter set and disintegration of the tracer wire. The gas ignited resulting in a house fire near the meter set. Company responders excavated the service line near the main and squeezed the plastic line to eliminate the source of gas. The new prague fire department put out the fire. The service was then cut and capped. The lightning strike may have also caused a leak in the above ground meter set. It was not clear if a potential lightning strike near the home and meter set was the primary cause or if it was due to a potential lightning strike to the ground and traveling to the meter set along the tracer wire.
